Well your first problem is that 'If' is not a keyword in C, whereas 'if' is. As an aside, you ought not put your call to strlen() inside the loop like you have. Change your code from:

Code:

for(i=0;i< strlen(the_file);++i)

to:

Code:

size_t len = strlen(the_file);
    for (i = 0; i < len; ++i) {

The reason for this is that strlen() walks through the string _every_ time you call it. And so if you call it inside the loop, you get a lot of overhead associated with that, because you are doing it a lot of times. Better to call strlen() once, save the result, and use it later within the loop.
