Base10 to Base n converter

well I guess im a c/c++ noob (although im majoring in programming, im only a freshman) but anyway, after taking a class on binary, octal, hex, conversions,a dn that sort of thing, I decided to use my limited knowledge to whip up a converter. Tell me what ya think and throw in any suggestion you might have.

Code:

---

//Decimal to Base 'n' Converter
//Converts any positive decimal number (up to 4,294,967,295) to base 'n'
//'n' being any base between 2 and 16
//Written by P4r4digm


#include <iostream>
using namespace std;
int main()
{
    //declare variables
    int convertFromCopy, digit, convertTo;
    unsigned int convertFrom;
    char playAgain = 'y';
    string stringDigit, answer;
   
    //allow game to loop without ending
    while (playAgain != 'n') 
    { 
        //delete pervious answer if run consecuteively
        answer = "";
       
        //Get user input
        cout << "Enter the number you wish to convert: ";
        cin >> convertFrom;
        cout << "Enter the base to convert the number to(max: 16): ";
        cin >> convertTo;
       
        //createcopy of original input to display later
        convertFromCopy = convertFrom;
       
        //continue dividing until original input is 0
        while (convertFrom != 0)
        {
            //calculate digit through use of modulo   
            digit = convertFrom % convertTo;
           
            //declare conversion variable (from int to char)
            int asciiConversion = 48;
           
            //for loop converts digit from int 0-15 to char '0'-'9', 'A'-'F'
            for (int i = 0; i < 16; ++i)
            {
                if(digit == i)
                stringDigit = asciiConversion;
               
                asciiConversion += 1;
               
                //skip from 9 to A on the ascii table and continue
                if (asciiConversion == 58)
                asciiConversion = 65;
            }
           
            //tack on converted digit to the beginning of the answer string
            answer = stringDigit + answer;
           
            //divide original input by conversion constant and loop
            convertFrom /= convertTo;               
        }
        //Show original input, base to be converted to, and converted number
        //and ask to repeat
        cout << convertFromCopy << " written in base " << convertTo << " is:\n" << answer << "\nAgain? (y/n)";
        cin >> playAgain;
    }   
    return 0;
}

It's well done.

Code:

You could replace the above code with this:

Code:

---

        if (digit < 10)
                stringDigit = '0' + digit;
        else
                stringDigit = digit - 10 + 'A';
