The first mistake which you have here is using feof function and i cant really see anywhere that you are trying to read something from a file. If you are trying to read from a file you need to open a file first

Code:
FILE *ptr;

if( ( ptr = fopen( <filename>, <mode> ) ) == NULL )
{
     printf("Error: File cannot be opened\n");
     return 1;
}

and then read the file
Read this on why feof shouldn't be used FEOF
