I have to make a program that reads a sentence, one character at a time, from the keyboard into a string class object. The entry will terminate with a (.). Then I have to search the array to determine how many times a particular character, specified by the user, occurs in the sentence. Am I on the right track?

CODE
#include "stdafx.h"
#include <iostream>
#include <string>
using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
    string str;
    char ch1=0, i;

    cout << "Enter a sentence: ";
    getline(cin,str,'.');

    cout << "Enter a character you would like counted: \n";
    cin  >> ch1
    for(i=0;i<str.length(); i++)
    {
    return 0;
}

All you need to do is loop through the characters in the string. Remember each character is nothing but an array of characters. Compare each one with the character that the user entered. Here is the product...

CODE

int count = 0;

for(i=0;i < (int)str.length(); i++)
{

    // If the character in the string equals the user's character, increment the count.
    if (str[i] == ch1) { count++; }
}

// Print out the total number of characters found
cout << "Total number is: " << count << endl;


That is all there is to it. Oh and don't forget the semicolon after the line cin >> ch1;.

Enjoy!
