            '8', '9', 'A', 'B', 'C', 'D', 'E', 'F' };
    int convertedNumber[64];

    int numberToConvert;

    int nextDigit, base, index = 0;

    printf ("Number:");
    scanf ("%d", &numberToConvert);
    printf ("Base: ");
    scanf ("%d", &base);

    do {//from   w w  w .  j a va 2  s.com
        convertedNumber[index] = numberToConvert % base;
    
        ++index;
    
        numberToConvert = numberToConvert / base;
    } while (numberToConvert != 0);

    printf ("Converted number = ");
    
    for(--index; index >= 0; --index) {
    
        nextDigit = convertedNumber[index];
    
        printf ("%c", baseDigits[nextDigit]);
    }
    printf ("\n");
