writing a program called tail like the one in unix

Hi can someone help me. I have to write a program called tail that will read lines from a file until it comes to the EOF, then the program should print out the last n lines of input. Its similar to the tail in unix. Thanks

Code:

#include <stdio.h>
#include <stdlib.h>
int main ( void )
{
   char buf[1024]={0};
   sprintf( buf, "tail %s %s", argv[1], argv[2] );
   system( buf );
   return 0;
}

It doens't get much simpler than that. Seriously, post your code. Read the god damn homework post and the FAQ.

Quzah.

Have you figured out how to implement the opposite command 'head', to print out the first 10 lines of a file?

It doesn't take much to get from one to the other.
