Normally, when we want to know the size of an array we use
sizeof(array) but how are going to know the size of the file pointed by fp i.e. FILE *fp? Please help!

you can use size = ftell(fp);
to do this you must first position the file position indicator at the end of the file, this is done using
fseek(fp, 0L, SEEK_END).
the value returned by ftell is the size of your file as a long int
