I am making a cd key replacer that will input the new cd key, change the key into base 24 then hex, and put the key into the registry. I am trying to figure out how to go from decimal to base 24 (I go to binary along the way). The numbers here are inputted as hex with a comma and no spaces after each value. At the point where I output values (at the bottom of my code), regardless of what I plug in, the first four are zero, and the fifth is always 2293672. Any suggestions on how to fix this?

int values[119] = {0}, reverse[119] = {0}, z = 15;
    char hex[14][1], hexrev[14][1], rad24[24];
    int i = 0;
    cout << "What number would you like to convert: ";
    for(i = 0; i < 15; i++)
    {
    hex[i][0] = cin.get();
    hex[i][1] = cin.get();
    cin.ignore(99999, ',');
    hexrev[z][0] = hex[i][0];
    hexrev[z][1] = hex[i][1];
    z--;
    }
    cout << hexrev[0][0] << hexrev[0][1]
    for(i = 0; i < 15; i++)
    {
    if(hexrev[i][0] == '0')
    {
                 values[4 * i] = 0;
                 values[4 * i + 1] = 0;
                 values[4 * i + 2] = 0;
                 values[4 * i + 3] = 0;
    }
    else if(hexrev[i][0] == '1')

You don't need anywhere near this many lines to convert from hex to binary. I would convert from a hex character to an integer from 0 to 15, then just do this:

int hexValue;
// code to put a number from 0 to 15 into hexValue;
values[4 * i] = hexValue / 8;
values[4 * i + 1] = (hexValue % 8) / 4;
values[4 * i + 2] = (hexValue % 4) / 2;
values[4 * i + 3] = hexValue % 2;

This shortening of the code might help you debug.
