Explanation

The fseek() is used to move the pointer at any position in a file. It is used in programs where we want to read or write data from/to a specific position in a file. It has the following syntax - fseek(filepointer,int bytes,int offset) where file pointer is a pointer pointing to a file. bytes - is the number of bytes that we want to move. offset - denotes the position from where we want to move.for example  fseek(fp,10,0) will move the pointer 10 bytes from the beginning.
