here is a hint check the function ftell…
long ftell( FILE *stream );
and …
The ftell() function returns the current file position for stream, or -1 if an error occurs.
First thing the return type is not is accordance to function return type.

More commonly, we pack this onto one line:
if ((p = malloc(100)) == NULL)
{ // allocate 100 bytes
printf(“Ooooo! Out of memory error!\n”);
exit(1);
}
Hence if we define ch = malloc(1) it will allocate 1 byte of memory.
