C/C++ :: Recursive Counting Occurrences
Apr 28, 2014
I have the following code that does not work. It prints out 1 when it should print out 5 and 3 respectively. I know that the code is not the pretties due to ( *arr == value) but i am just learning C++.
Spoiler
template <typename T>
int countOccurrencesRecursively(T* arr, int size, T value){
//the base case is when the the array is empty
if(size == 0) return 0;
else return *arr == value + countOccurrencesRecursively(++arr, --size, value);
[Code] .....

I've been struggling with this for a while, I have to write a function that accepts a word (in my case the word is "the") and file pointer, and counts the number of times the given word appears (case insensitive) within the file associated with the pointer. This means the two words "the" and "THE" should both be counted.
Here is my code:
int WordCount :: countWords(string wrd) {
int counter=0;
string temp = "";
while (getline(*file,temp)) {
for (int i = 0; i < temp.length();i++) {
[Code] ....
This is what I have come up with, but I get an incorrect value. It was suggested to us to consider using the strcpy() or strstr() functions, but I don't know how to use them.

My maze algorithm must be able to count total steps. He is not allowed to "jump" from a deadend back to the cross-way he originally came from.
Code:
int R2D2Turbo::findIt(Labyrinth* incLab, int x, int y){
if ((x == incLab->getExit().x) && (y == incLab->getExit().y))
{
return 1;
[Code] .....
Due to the nature of recursive algoirthms, he jumps instead of moving the way back from the deadend one by one... The only solutions I could think of are way overloaded...

Problem i have is that is keep saying "error: file". I have test.txt. Byway i am using xcode 6 and I using C.
#include <stdio.h>
/* counts words in the file */
int main(void) /* C89 ANSI */
{
FILE *fp;
int r; /* a variable for result of a function, returning int */
size_t n; /* the words counter */

I want do delete all occurrences of a char in a given string, but I really don't see my error in the code. Here is how I did it:
Code:
char *input = "example_string";
int len = strlen(input);
char *new_line[len];
char bad = 'e'; //the one to delete
int i;
int j = 0;
[Code]...
I get segmentation or bus errors.. And I also don#t understand the warning I get. new_line is an array of chars, and I am trying to assign to it a certain char.

I am supposed to read(scan) data from a folder with multiple(21578) text files, and file names are numbered from 1 to 21578,and read each word that occurs in a text file, and count the number of times it occurs in the entire folder,i.e; in all the files how do i go about it? I've tried this so far..but it isn't working..
#include <iostream>
#include <map>
#include <string>
using namespace std;
void incrementString(map<string, int> &theMap, string &theString) {
if(theMap.count(theString)) {
[Code] ....

This could be non contiguous. As an example
string1: "Hello"
string2: "Heelblloo"
occurrences of string 1 in string2 is 2*3c2*2=12
among 2 e's in string 2, we can select only one and thus 2 possible ways.similarly for l and o.

So I'm supposed to create a program that will read off words from a .txt file,and use a function to count the number of vowels in each word and then display the specific vowels and their frequencies. ex. if the word is: butter the output would be:
a:0
e:1
i:0
o:0
u:1
This is what I have so far, but I'm running into some problems.
#include <iostream>
#include <string>
#include <fstream>
using namespace std;
void PrintFrequencies(string str);

How I would go about counting lines from a file at the same time as extracting words? I need to know the line number to output what line the word is misspelled on. I tried getline and using sstreams but I could not get it to work.
void SpellCheck::checkValidWords(const string& inFileName) {
string eachword;
ifstream istream;
istream.open( inFileName.c_str() );
if ( !istream.is_open() ) {

I now know how to count integers with while loop but I'm not sure how to count the integers with array.
So the question is:
1. program should keep reading integers as long as the integers are within [0,9999]
2. when user typed the integer not between 0 to 9999, the program print out the numbers of integers that were typed.
Sample
3
3
3
9999
9999
-1
You entered 3 3 times.
You entered 9999 2 times.
#include <iostream>
using namespace std;
int main() {
int i=-1;
int x;
int numbers[10000];
[Code] ....
I cannot use "do" ....

How Can I continuously call the Count(); Function again after the first number?

How to make this program that the output is a number that counts up to infinite (or we say just like a timer but there's no minute just all whole number counting up ) using for loop ? and when the number changes it also change in color !
and the color of a number is according to the color attribute of console output.

I am unsure how to write a function which modifies the content of the 1D character array and counts the number of the vowels. the following is the array that i have.
char text[MAX+1] = {'T', 'e', 's', 't', 'e', 'r', EOT};
the output that i am trying to produce is should look something like this
the number of vowels is 2, e, e.
I am unsure how to do this.

I'm trying to write a program that should output, in a tabular form, the name of the algorithm, size of the array, number of comparisons and number of swaps. I am really, really, really bad at arrays and comprehending how to output variables from several. Especially in tabular form />
Here is what I have written thus far:
#include <stdio.h>
#include <stdlib.h>
#define MAX_ARY_SIZE 10
[Code]......
My questions:
1 - How do I make the array size change from 10 to 100 to 1000?
2 - How do I populate the array's with random non-repeating numbers?
3 - How do I make each algorithm count the # of comparisons and swaps?
4 - How do I return the counted comparisons AND swaps (in one return function??) and then print them?

This function check a set of values from a text file and show it on the output.
void MatchNumber(int b){
vector<Rect> rects;
ifstream theFile("CheckNumber.txt");
[Code]......
I want to calculate how many times the number is repeated. So I have used freq[num] in that function. But I am getting the output like this-
The common number is = 5
The 5 repeated = 1 times
The common number is = 6
The 6 repeated = 1 times
The common number is = 4
The 4 repeated = 1 times
The common number is = 5
The 5 repeated = 1 times
The common number is = 5
The 5 repeated = 1 times
The common number is = 8
The 8 repeated = 1 times
The common number is = 9
The 9 repeated = 1 times
The common number is = 6
The 6 repeated = 1 times
The common number is = 6
The 6 repeated = 1 times
The common number is = 8
The 8 repeated = 1 times
So the value of freq[num] only shows 1 instead of calculating the number of repetition.

#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main() {
int num;
int count = 0;
[code]...
The last number in the numbers.txt file is: -1, and I am not allowed to include it in the calculation of total, average, etc.
I tried to make an if statement to not include -1 but, I can't figure it out. This compiles with or without my num == -1 statement.

So here is a function.. now I need to find how many times LINE 1, LINE 2, LINE 3 executes:
for (int i = 0; i <= n; i++) {
CODE 1;
stateCount1++;
for (int j = n; j > 0; j = j-3) {
[Code] ....
For CODE 1, its n+1. But I am having trouble finding the number of executions for CODE 2 and CODE 3.

This code is compile but must have some upgrades :
1. The algorithm count double space how 1 word this is not correct. Probably have to add condition like ' '&'a-z'||'A-Z' but in unknown to me reason this is don't work
2. If there is one words without space then counted don't detect this word, it is incorrect.
Code:
#include <iostream>
using namespace std;
int main () {
char ch;
cout <<"enter your text: " ;

I have recently hit a stump with C++ and have been getting pretty frustrated with this assignment. I just can't seem to find out how to start the assignment. Basically for the first part of the assignment, I need to find the number of characters in this .txt file my teacher provided for me. The only exception is that I can only count the actual letters themselves, not spaces or punctuation. How would I go about doing this? I have read about functions like isalpha but can't figure out on how to fit them into code to do the first part of this assignment.

I am writing a program when the beginning it you have to pick which step to preform out of a few steps. Once you choose the step. The user is asked to input what is asked and it should preform it. I have completed most of my steps but the one step giving me a hard time is converting a user inputed sentence into all lowercase letters, and then count the words of it. My program starts out like this if you pick this step Code: else
if (choice == 3) {
/* Gather user's input */
printf("
You have chosen to convert a sentence to all lowercase letters and count the words
"
"Enter the sentence: ");
gets ( sentence );
Call the function to convert the whole sentence to lowercase and count the number of words */
lowercase_string ( &sentence);
countSentence ( &sentence);
} /* End if statement */
this is the easy part in which I presume I did correctly, but now this is where I am getting the problems:
/* Prompts user to enter a sentence and convert it to lowercase and count the number of words */
void
countSentence (char *sentence)
void
lowercase_string (char*)
{
[code]....
I want to output the original sentence, then the sentence with all lower case letters, then at last output the number of words in the sentence. I declared all my variables up top, and I am wondering where my mistake is. When trying to compile it, I only get syntax errors which I don't understand.

it looks like a popular method for determining the total lines in a file is to read the entire file character by character in search of ' '. I have a file with 5 lines, but for some reason this code isn't finding any instances of ' '. Is this possible? Is there a better way to get the number of lines in a file?
The file looks like this:
Code:
NAME: John
FRIEND 1: Steve
FRIEND 2: Andrea
FRIEND 3: Ken
OCCUPATION: Programmer
Code:
FILE *f = fopen(currentFile, "r");
if (f == NULL) perror ("Error opening file.
");
int ch, lines = 0;
while(!feof(f)){

Code:
#include <stdio.h>
int main(){
double nc;
for (nc = 0; getchar() != EOF; ++nc)
;
printf("%.0f
", nc);
}
It works well and I am using ctrl-D as my EOF. Now I understand that C is not really a language for dealing with text, which is why I am learning it more in depth, my degree was in robotics, and I think C is definitely the best place to be for me. So this may just be a quirk, but if I type more than 10 characters, I get the right answer from the program, however, if I type less than 10, for the sake of argument I type Hello and then return, if I at that point do ctrl-D, I get the answer 6D?
The 6 is right 5 letters and a return character, but what is the D?
