#include <sstream>

stringstream toString;

int num = 55; //Your integer
string stringNum; //Your output

toString << num;
stringNum = toString->str();
toString->str(""); //Clear toString so you can use it again

This code converts an integer into a string. Hope it helps.

Here's some more reading on stringstream if you're interested:

Try this:

#include<iostream>
#include<sstream>
#include<string>
using namespace std;

int main()
{
     ostringstream oss;
     double number = 0.0;
     string string_number;

     cout << "Enter number:  ";
     cin >> number;

     oss << number;
     string_number = oss.str();

     cout << "\n\nThe number you entered is:  " << string_number;

return 0;
}

The above example is based on this tutorial: http://faq.cprogramming.com/cgi-bin/smartfaq.cgi?answer=1045689663&id=1043284385

in a loop, use % operator to get the last digit, then /= operator to shift digits right and drop the last digit.

#include <iostream>
#include <string>
#include <algorithm>

using namespace std;

int main()
{
    int x = 123;
    string a;
    while(x > 0)
    {
        int n = x%10;
        x /= 10;
        a += (char)(n + '0');
    }
    reverse(a.begin(),a.end());    
    cout << a << '\n';
    return 0;
}

[edit]Or better still, use previously posted examples which use stringstream class. They are a lot simpler than what I posted here.
