C/C++ :: String Of Characters - Sorting Alphabets And Numbers
Apr 20, 2014
My program reads a string of characters. Prints all occurrences of letters and numbers, sorted in alphabetical and numerical order. Letters will be converted to uppercase.Other characters are filtered out, while number of white spaces are counted.
the problem is it crushes when i run the program
Here is my code
#include <iostream>
const int SIZE = 100;
using namespace std;
int main() {
char *pStr, str[SIZE] = "", newStr[SIZE] = "", ch;
int count = 0, i = 0, j;
[Code] .....

I am unable to create an array which has to content elements(1E, 2E, 3E, 4E). I tried using char however I am unable to display as it only shows the letter E.

I have a upcoming C++ exam. I would like to write a program to convert INDIVIDUAL digits into words.
E.g 678 = six seven eight[/size][/b]
I have the following code:
//Program to print individual digits in words
#include<iostream>
using namespace std;
int main() {
int num;
cout << "Enter a number between 0 and 9999: ";

I'm trying to create a program that counts the amount of alphabetical characters, numbers, blanks and total amount of characters in a string a user gets to enter. The user also quits the program manually by pressing CTRL + D (in linux terminal).
These are the results I get from the code so far by typing in "hello cplusplus 123 c++" CTRL + D.
The string had:
Alphabetical characters...: 0
Numbers...................: 0
Blanks....................: 3
Total amount of characters: 20
So I can't seem to find a way to count the amount of alphabetical characters and numeric characters.
Here's my code:
#include <iostream>
#include <string>
#include <iomanip>
#include <cctype>
#include <sstream>
using namespace std;
int main() {
string tecken;
[Code] ....
The reason why I declared cctype is that I think I should use the isalpha, isdigit and isblank functions but how I am supposed to do that.

I am looking for a way to sort a string just by the alpha characters, not by the ASCII table. Therefore
string sort(string name) {
sort(name.begin(), name.end());
return name;
}
will not work. And I am looking for the most simple way to go about it!

I'm trying to write a lot of sample code to practice but I can not figure out how to take a string and sort each character in order of their increasing ASCII codes. I'm getting stuck trying to separate each letter to determine it's ASCII code. I know I have to use an array somehow, So far, this is my code:
#include <stdio.h>
#include <stdlib.h>
#define _CRT_SECURE_NO_WARNINGS

so my question is i want to print characters,no string just an array of characters,i do this but it s not working,maybe i have to put the '' at the end?
Code:
int main() {
int i;
char ch[5];
for(i = 0; i < 5; i++) {
scanf("%c",&ch[i]);

Im supposed to find the common characters between two string characters, assuming that the user wont input duplicate letters like ddog. When I run my code I get an output of a question mark upside down. Here is my code with comments on what each part is supposed to do
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main(){
char str1[20], str2[20],remp = ' ';
int size1,i,j,temp;
printf ("Input the first string");

I am stuck in this program, Be given a string of chars, where each single char belongs to the following alphabet: a..zA..Z0..9 (So, in the string there are only lowercases, uppercases and digits. No blank, no comma, ...). For every char of the given alphabet, count how many times in the string
1-- the char belong to a sequence of identical chars whose length is at least three (i.e.: in the string cc74uyrpfccc348fhsjcccc3848djccccc484jd for three times the character 'c' satisfies this condition)
Code:
#include<stdio.h>
#include<conio.h>
#include<string.h>
[Code]...
2-what is the longest substring of characters strictly rising interm of ASCII code(the following is greater (>) of the previous)
3- what is the longest substring of successive characters interm of given string rannge (i.e.: fhkjshdfruytyzABCDEfglsj => 7)

I'm trying to take a users input and break it up into four separate numbers, then take those numbers and arrange them from smallest to largest.So far I can't seem to get them working right.
Code:
# include <stdio.h>main ()
{
int inputVariables[4]; //where userinput goes after being broken up
int arrangedValues [4];// the user values arranged lowest to highest
int i;
int j;
}

I have been working on this program for days now and for some reason my program will not write to my third file. It will call all of the integers that I need it to call but it will not write them out to a file. How to use my loop correctly.
#include <iostream>
#include <fstream>
using namespace std;
int file1();
int file2();
int file3(int);

I need numbers next to each other to be sorted (in increasing order).On the CPU I'd do something like this:
for(int i=0; i < length; i+=2) {
if(a[i]>a[i+1]) {
switch places...
}
}
But how would I do this using parallel_for_each (C++AMP) ? I need this for some algorithm that works with very long arrays and I think GPU would do this faster than CPU (even if I use all threads).

I'm writing a simple program to sort numbers through use of a pointer. I've always been bad with pointers, and I tried to use a typical temp value to hold the value, but i feel like I am over doing it.
#include <iostream>
using namespace std;
void SortTests(int *, int);
int main() {
int *ptr;
int tests;

I think it comes from having to align the data in the output file. How to start this is to use a function to read in all the characters using a while loop. Then read in all the digits in a separate function. When it comes to outputting the data in the correct format I'm lost, so for now if I could figure out the functions that would be awesome. A final note we have not gotten to using strings so the I'm trying to use getc, fgetc, and ungetc.
Write a program to compute average grades for a course. The course records are in a single file and are organized according to the following format: Each line contains a students first name, then one space, then the students last name, then one space, then some number of quiz scores that, if they exist, are separated by one space. Each student will have zero to ten scores, and each score is an integer not greater than 100. Your program will read data from this file and write its output to a second file. The data in the output file will be the same as the data in the input file except that there will be one additional number at the end of each line: the average of the students ten quiz scores.
The output file must be formatted such that first and last names appear together in a left justified column that is 20 characters wide. Each quiz score should be listed in a right justified column that is 4 characters wide, and the average should appear in its own right justified column that is 10 characters wide.
Note that if a student has fewer than 10 scores, the average is still the sum of the quiz scores divided by 10; these students are assumed to have missed one or more of the quizzes. The output file should contain a line (or lines) at the beginning of the file providing appropriate column headings. Use formatting statements to make the layout clean and easy to read.

I need to open a file that has multiple lines that look something like this, " black box 100.01 33.5 78.93". What this shows is the coordinates of the black box. Lines will have different objects with different coordinates. I need to create a loop that will read this file and tell me when a black box is found by displaying a message. I don't need to know how to create this file. I don't need to display the entire file but rather have it search for black boxes.

I currently have a .csv file that should only contain numerical values however there are errors in some columns that mean there is text included. I am wondering what the best way of going about removing these characters would be.
I am looking at using : str.erase(std::remove(str.begin(), str.end(), 'xxxxxxx'), str.end());
For this I will need to read my data into a string and then remove the alphabet from that string. I am currently doing this like so (I use the '?' as a delimiter because I know there are none in my file).
#include <iostream>
#include <fstream>
#include <algorithm>
using namespace std;
string Weather_test;
char chars[] =
[Code] ....
The problem with this is I don't know what to do around the chars[!eof] part.

For my project I have to sort 5 numbers and 5 names using a template bubble sort. I have one header for the numbers, and one for the names. This is what I have so far for my testing page:
#include "Floatheader.h"
#include "Nameheader.h"
#include <string>
int main ()
myFloat obj1;
myFloat obj2( 2.2, 5.1);
[Code] .....
I have to create a template to look like this: template<>....with a class inside the arrows. Then, I have to use bubble sort to sort the 5 names and number objects I have created. Sorting the names and numbers and also using templates?

We've only covered up to Functions and how to use reference variables inside the function parameter.
One of the hw problem that was assigned was to write a void function that takes three parameters( num1, num2, num3) by reference and sorts their values into ascending order, so that num1 has the lowest, num2 the middle value, and num3 the highest value. For example, if user enters: 14, -4, 8, then the output should look like this:
-4
8
14
I've completed the program with a bunch of if/ else if statements but I was wondering if there was a more efficient way to sort the numbers. Bear in mind, we've only covered materials up to functions so I can't use any other new techniques that we haven't cover yet. Here is my code:
// This program will take three int parameters by reference and sorts their value into ascending order
//so that num1 has the lowest value, num2 has the middle value, and num3 has the highest value
#include <iostream>
using namespace std;
// declare function with reference parameter that with sort numbers
void sortNum(int &, int &, int &);
int main ()
{

I need to convert characters in a input file to numbers in output file and display both the characters and numbers in a console window.Only 7 numbers can be displayed, the rest needs to be dropped.The input file contains the following data, with one number per line:
CALL HOME
GET LOAN
Hi THERE
BYE FOR NOW
For example, once the first number in the input file has been processed, the console window should display the following: CALL HOME 225 5466.
The output file should now also contain the number:
225 5466
Currently my console is displaying the following:
Enter the input file name.
infile.txt
Enter the output file name.
outfile.txt
2554663Invalid Input
4385626Invalid Input
4Invalid Input
84373Invalid Input

BYE FOR NOW
#include <iostream> // for screen/keyboard i/o
#include <fstream> // for file
#include <cstdlib> // for exit

Simple program to convert files to XML files. However I am trying to narrow down why my code is not working. I am reading a line that looks like "2001 Joe Dirt Los Angeles", then the next few lines are followed by text and the the fifth line looks like "---End of Description---".
So here is the file
2001 Joe Dirt Los Angeles
Home is where you make it
Best movie ever(but not really)
But seriously
---End of Description---
Here is example code to test the process
string line;
while(dataFile >> line) {
getline(dataFile, line);
cout << line << endl;
}
My returning output is
[space]Joe Dirt Los Angeles
[space]Home is where you make it
[space]Best movie ever(but not really)
[space]But seriously
My test code is skipping the date on the first line but replacing it with a space. Then it is skipping my fifth line which reads "---End of Description---". Now if I take the code out of the while loop and hard code in five lines of output (x5 getline(dataFile,line); cout << line << endl;) then my code works as expected. I get all of the information. Date and the fifth line.
It looks like when I am testing for the EOF it is also taking in the numeric value at the beginning of the first line. However, that does not explain why it is dropping that fifth line.
