C/C++ :: Program To Print Histogram Of Lengths Of Words In Its Input
Mar 4, 2014
Write a program to print a histogram of the lengths of words in its input. It is easy to draw the histogram with the bars horizontal; a vertical orientation is more challenging.
See [URL] ....
I'm trying to do this exercise from K&R on my own (with my own code), but I'm receiving a signal (Illegal instruction (Core dumped)) when the input is too large.
#include <stdio.h>
#define MAXWORDLENGTH 10
int main(void) {
int c; /* Character read */
long length[MAXWORDLENGTH + 1];
int reading_word = 0;
int word_size = 0;
[Code] ....
Where the problem might be occurring. I tried debugging with GDB but found no useful information.
Program received signal SIGILL, Illegal instruction.
0x00007ffff7a3b76e in __libc_start_main (main=0x4005d4 <main>, argc=1,
ubp_av=0x7fffffffe2a9, init=<optimized out>, fini=<optimized out>,
rtld_fini=<optimized out>, stack_end=0x7fffffffe298) at libc-start.c:258
258libc-start.c: No such file or directory.
The program output is also wrong when tested with the code provided at the link given above.

C programming: I want to creat a program that asks the user to input the integer lengths of three sides of a triangle, and if so whether the triangle is a right-angled, acute or obtuse one. i am having some doubts about the if, else if statements. I never seem to know how and in what order to use them.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
int main(int argc, char *argv[]){
int SideA;
int SideB;
int SideC;
}

I want to create a vertical histogram in my code. I already made it go vertical but not the way I want it.
Example:
I want it like this:
Range1 Range2 Range3 Range4
And asterisks under each one, depending on the user input. (My code is below and doing it on here doesn't make it come out correctly)
But what I've managed to do is this:
Range1
*
*
*
Range2
*
*
Range3
*
*
*
*
Range4
*
*
Which I don't want. I want everything else to stay pretty much the same since I can only use some features such as Arrays and really basic functions.
Here is my code: (Worked fine last time I used it and I am doing it on Visual Studio 2010 (at uni) and 2013 (on my laptop)).
#include <iostream> //Start of code
using namespace std;
int MarkValueInput; //Mark entered by user
//Counter variables for ranges in While Loop
int counterlow; //Counter for low range
int countermidlow; //Counter for mid-low range
int countermidhigh; //Counter for mid-high range
int counterhigh; //Counter for high range
[Code] .....

I made a simple program to compute the lengths of a triangles sides, but when I enter 30 for angle and 10 for hypotenuse I get the opposite side is -9.880316 and the adjacent is 1.542514.
#include <stdio.h>
#include <math.h>
main() {
float angle;
float hypotenuse;
float adjacent;
float opposite;

I've reached a point in "Jumping into C++" where I need to make a program that converts input numbers into their word equivalent.
So far I've made it work for numbers 0-9999. I've tried implementing 10000-99999 but there are problems with the order of the words printed (57865 would print fifty thousand seven thousand eight hundred sixty five). But besides that, the program is absolutely enormous (for me) and I'm wondering if it can be shortened. Keep in mind I can only use loops and if statements so far. Here it is:
Code:
#include <iostream>
#include <string>
void extras(int e);
void digits(int x);
void tens(int xx);
void hundreds(int xxx);
void thousands(int xxxx);
//void tens_of_thousands(long xxxxx);

I tried to work on this program for while, but I am not able to get it to work
Directions:Write a program that reads an integer n from the user.
Display the first 100 numbers, with newlines every n numbers, using % operator
#include <stdio.h>
int main(void){
int a = 0;
int b = 99;
printf("Enter a number: ");
scanf ("%d", &a);
[Code] ....
When I run this code it asks me to enter a number. It doesn't matter what number I enter it gives me the numbers from 1 to 100 in one horizontal line.
I want this program to do something like this:
for example if the user enters n=6 the program should give:
0 1 2 3 4 5 6
7 8 9 10 11 12 13
and so on

I am creating a trie (not a tree but a trie). I have the following structure:
Code:
struct tnode {
bool is_word;
list *children;
};
struct trie {
int length;
struct tnode *first;
};
list *children is a linked list that contain pointers to tnodes. For example: I have a trie with the words cup and cut:
c
u
/
p t
Given the example above you have the following linked lists:
1. [c] that contains a pointer to linked list 2.
2. [u] that contains a pointer to linked list 3.
3. [p, t]
Now I want to print the trie like:
cut
cup

Write a program that prompts the user for the name of a file. Then it opens the file, and counts the number of words and lines in the file, and prints out those counts.
I think I possibly could somehow use a counter to increment using getLIne() until getLine() returns NULL, but the problem is, I'm worried if I try that, a file that looks like this:
Bla bla bla bla bla lkfdljkfaklafdskjladsjkdfkjlkdfjdfshafdsjkjrerjkkjfaddjkfsafkjdjakdfsjkasfjkjkfdskjldfjkfjkdjfkdsakdjfkjfdkjdfskjfdsk
jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjdfkerea
blkjadkjlfdskjldfkjlfdkjfdjkdfsjkldfskljfksfdljfd
Only register four lines and not get the one after the fourth line.
So I was thinking of something like
Code:
#include <iostream>
#include<ifstream>
#include<cstring>
#include<string>
#include<vector>
#include <cstdlib>
using namespace std;
iostream keyboard;
ifstream file;
iostream cin;
[Code] .....
Did I do that right? Will that count the number of words and number of lines correctly?

I am trying to write a program that counts specific words that a user inputs "Howdy/howdy/Whoop/whoop" (yes I go to Texas A&M, hence those specific words) I am having an issue where it wont count the first word even if it is "Howdy"
For example if I put it:
"Howdy howdy whoop Whoop" - it only outputs that it counted 3 words
now if I were to do:
"Hello Howdy howdy whoop Whoop" - it would count 4.
Code:
#include "std_lib_facilities_4.h"
int main(){
cout << "Please enter desired words, when you have entered all words, please type CTRL+d (EOF Command)
" << endl;
//It was assumed that EOF command was going to be used here hence the necessity of 'CTRL+d'
vector<string>words;

The basic idea of this exercise is to generate words from a user-input, seven-digit number(a phone number). The code runs, but for some reason, I can't get it to print the numbers into the file.
Code:
/*Write a program that will generate a word based on a randomly generated, seven-digit number. there should be 2187 possible words. Avoid "phone numbers" that begin with 0 or 1*/
#include<stdio.h>
#define PHONE 7
void wordGenerator(int number[]);
void wordGenerator(int number[]) {
//loop counters for each digit in the number

I'm trying to write a short program that takes the input from a user and trims any leading/trailing white space, and then checks how many words are in the string. Problem is, I'm only allowed to use stdio.h and stdlib.h. How can I accomplish this? Also, how would I check if any of the characters which were entered aren't either a number, letter, or '-'?

I trying to get input from the user and split into words that separated by a space.
string s = "1 2 3";
istringstream iss(s);
int n;
while (iss >> n) {
cout << "* " << n << endl;
}
The code above works fine but i want to get the string from user. the code below only prints the first word and trashes rest of the words in the sentence.
string s ;
cin>>s;
istringstream iss(s);
string n;
while (iss >> n) {
cout << "* " << n << endl;

I'm trying to write a little C++ wrapper around the PolarSLL SHA-512 / 384 implementation, the source code of which you can view here: [URL] .....
The problem I'm having is that the length of the digest is not always 64 bytes (for sha512) or 49 bytes (for sha384) as it's supposed to be, it often is, but not always.
I have pretty much used the code as it is on PolarSSL's website, except for wrapping it in an "impl" namespace. I also ran the self_tests, which all passed.
Here's the code I'm using to wrap the PolarSSL implementation:
namespace {
void sha4(const std::string& input, const sha_t& type, std::string& result) {
bool is_384 = (type == sha_t::SHA_384);
const unsigned char* in = reinterpret_cast<const unsigned char*>(input.c_str());
[Code] ....
When I do a strchr() for '' on the original (non-hex) values, the pointer position returned is the same as the checksums length, so I'm wondering if perhaps the sha4 implementation would shift bits around and one of them happens to become a '', null terminating the hash early?

I have program that is supposed to read in a story from an input file and separate the words and output the lines on which the word occurs. It needs to read in another input file that has a list of words (1 per line) to ignore. i.e. skip them when running through the story. This is what I have so far, I've changed multiple things trying to get it running....
#include<iostream>
#include<fstream>
#include<map>
#include<set>
#include<vector>
#include<string>
#include"split.h"

Im writing a c program that reverses the words in a sentence,
Example:
you can cage a swallow can't you?
you can't swallow a cage can you?
I have it all working, except the fact that I dont know how to get the words themselves to turn around. Heres my code and an example of the output im getting.
Output Im getting:
Enter a sentence: you can cage a swallow can't you?
Reverse of sentence: uoy t'nac wollaws a egac nac uoy?
Code:
#include <stdio.h>
#include <stdlib.h>
#include <ctype.h>
#define MAX 200 /*Decent number of chars for a sentence*/
int main()

Write a C++ program that reads lines of text from a file using the ifstream getline() method, tokenizes the lines into words ("tokens") using strtok(), and keeps statistics on the data in the file. Your input and output file names will be supplied to your program on the command line, which you will access using argc and argv[].
You need to count the total number of words, the number of unique words, the count of each individual word, and the number of lines. Also, remember and print the longest and shortest words in the file. If there is a tie for longest or shortest word, you may resolve the tie in any consistent manner (e.g., use either the first one or the last one found, but use the same method for both longest and shortest).
You may assume the lines comprise words (contiguous lower-case letters [a-z]) separated by spaces, terminated with a period. You may ignore the possibility of other punctuation marks, including possessives or contractions, like in "Jim's house". Lines before the last one in the file will have a newline (' ') after the period. In your data files, omit the ' ' on the last line. You may assume that the lines will be no longer than 100 characters, the individual words will be no longer than 15 letters and there will be no more than 100 unique words in the file.
Read the lines from the input file, and echo-print them to the output file. After reaching end-of-file on the input file (or reading a line of length zero, which you should treat as the end of the input data), print the words with their occurrence counts, one word/count pair per line, and the collected statistics to the output file. You will also need to create other test files of your own. Also, your program must work correctly with an EMPTY input file – which has NO statistics.
Test file looks like this (exactly 4 lines, with NO NEWLINE on the last line):
the quick brown fox jumps over the lazy dog.
now is the time for all good men to come to the aid of their party.
all i want for christmas is my two front teeth.
the quick brown fox jumps over a lazy dog.
Copy and paste this into a small file for one of your tests.
Hints: Use a 2-dimensional array of char, 100 rows by 16 columns (why not 15?), to hold the unique words, and a 1-dimensional array of ints with 100 elements to hold the associated counts. For each word, scan through the occupied lines in the array for a match (use strcmp()), and if you find a match, increment the associated count, otherwise (you got past the last word), add the word to the table and set its count to 1.
The separate longest word and the shortest word need to be saved off in their own C-strings. (Why can't you just keep a pointer to them in the tokenized data?)
Remember – put NO NEWLINE at the end of the last line, or your test for end-of-file might not work correctly. (This may cause the program to read a zero-length line before seeing end-of-file.)
Here is my solution:
#include<iostream>
#include<iomanip>
#include<fstream>
using std::cout;
using std::ifstream;
using std::ofstream;
using std::endl;
using std::cin;
using std::getline;
void totalwordCount(ifstream&, ofstream&);
[Code] .....
Question: In the uniquewordCount() function, I am having trouble counting the total number of unique words and counting the number of occurrences of each word. In the shortestWord() and longestWord() function, I am having trouble printing the longest and shortest word in the file. In the countLines() function, I think I got that function correct, but it is not printing the total number of lines. Is there anything that I need to fix in those functions?

I wrote this code to search words in the file and display if the program found the word or not. when i write the words in the file on the same line (without the endl) like this :
w_toFile << "gilbert";
w_toFile << "lara";
w_toFile << "rana";
i can search any word.
but when i write them with the endl, the program can find only the first word. what can i do to make the program find any word even if they are each on a line?
here is the full code:
#include <iostream>
#include <windows.h>
#include <fstream>
#include <string>
using namespace std;
int main (void) {
string wordsearch;

Creating a C program that can pick words in a string or array and save it in different location, later combine everything in one string or array. It will be using simple programming C code. For example (arrays, pointer) but not interrupts or other string functions.
In a sentence like this:
Size= 70
$--GSV,x,x,x,x,x,x,x,...*hh $--GGA,hhmmss.ss,llll.ll,a,yyyyy.yy,b,x,xx,x.x,x.x,M,x.x,M,x.x,xxxx*hh $--GLC,xxxx,x.x,a,x.x,a,x.x,a.x,x,a,x.x,a,x.x,a*hh $--GSA,a,a,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x.x,x.x,x.x*hh
The program must capture the $--GGA string then extract from this string:
1) hhmmss.ss
2) IIII.II
3) a (if a = to N or S replace N or S with + or - respectively )
4) yyyyy.yy 5) b (if b = to E or W replace E or W with + or - respectively )
Save them in an array and display as well. After all the saving, the program should combine them to one string. That the final output.

I have a problem with how to print out all the numbers that the user enters the code looks like this so far:
Code:
#include <iostream>
using namespace std;
int main()
[Code] ....
I want the program to print out all the numbers that the user has entered after the program have said the higest and lowest number is ?. But I do not know how to do this I thought it could be something like this:
Code:
cout << input[0];
//or
cout << input[i];
/*
Because i is the number of how many enters of numbers the user can do*/ But that was totally wrong tried to do another "for loop" in the first for loop but that was meaningless because it can't change anything in the first "for loop".
