Problem with a simple C app. Calloc

I'm making this simple C program.  I'm using Calloc to allocate space to hold an array containing the number of instances of each letter in the file.

When I try to Calloc, or Malloc then memset the memory, one of the items in the array is not initialised to zero.  This is part of the array straight after initialisation:
......
Number of f: 0
Number of g: 0
Number of h: 134777
Number of i: 0
Number of j: 0
......

What did I do wrong?

Who wants to compile their C with a C++ compiler anyways? And I was speaking for C89, as C99 is utter shite compared.

The intent is plain based on the type of variable you're assigning to. If I have
int *i;
/* ... */
i = malloc(5 * sizeof(int));
it's pretty damn obvious what I'm allocating/doing. Adding the preceding (int *) is useless and adds clutter.
