Chr() or joining two different data types

Actually this is to do with C++. I would post it in the C++ section, but it looks too slow and I need an answer fairly quickly.

Is there a function which is equivelant to VB's Chr() function in C++? I'm new to C++ and I am converting some simple code from VB to C++ but it doesn't seem to be working. I want a function to return a string, but the string's length keeps changing. Here's the code if it helps:

Code:

---

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

int main()
{
    unsigned long        lngInput;
    unsigned long        lngOInput;
    string              strOutput;
    unsigned char        intChar;
    cout << "Please enter a number to convert to Base 32" << endl;
    cin >> lngInput;
    lngOInput = lngInput;
    while( lngInput != 0 )
    {
        if( lngInput % 32 < 10 )
        {
            intChar = ((lngInput % 32) + 48);
            strOutput = intChar & strOutput;
        }
        else
        {
            intChar = ((lngInput % 32) + 55);
            strOutput = intChar & strOutput;
        }
        lngInput = int(lngInput / 32);
    }
    cout << lngOInput << " in base 32 is " << strOutput << endl;
    return 0;
}

---

Yes, I know that it is returning an integer, but that's only because it won't work as a string. Once strOutput shows the right thing I will change it. intChar is the character I want to convert (using something like chr()).

Any help would be appreciated, thanks.
