Single and double quotes are very different things in C. In C, "A" means a string -- amounting to the array { 'A', '\0' }. And 'A' is just the number 65.

If I print out the m_array with something like this:

Code:
for (i = 0; i < DATA_SIZE; i++){
            printf("%x\n", m_array[i]);
    }


I get back an array of random numbers that I generated from another function:

Code:
 ./test | tail 
8885ffc9
77a822d5
bf34d05d
bc229af3
fc171fb9
ab7d3609
4815ef59
83facdc3
7d77bf58
881d17ea

Then I have another function that should randomly select an element from that array, or for any of the arrays from characters that match, and use one number to replace the letter given. Sorry if that wasn't clear.
Numbers that large won't fit in your input array. chars are numbers, but their range is only -128 through +127. It'll work fine if you use a separate array of type 'int' output.
