out of shere time constraint I'll repost my updated querey      I need to call a function form main, my f/p is
void CountLetters(string, length, freq[], SIZE)
string is my string*, length is the size freq is an array[26] size#26
I need to be able to search through the string find the count of each letter and assign into corrospontding space in the array ie freq[0]= # of a's, freq[1] = # of b's both upper and lowers.
I need the array set up that way so I can sort it with anther array that contains the alphabet, need to be able to count the letters and put the values in the array freq

Hasn't this been answered under "string search"? If not, how is this question different?

void Count_letters (char *string,int length,int *count,int size)
{
   int i;
   int ch;
   memset (count,0,sizeof(int)*size);

      for (i=0;i<length;i++) {
        ch=string[i];
             if (isalpha(ch) {
                  ch = tolower(ch)-'a';
           if (ch < size)
                     count [ch]++;
        }
    }
}
