Write a C program based on the following code: int p[2]; char *argv[2]; argv[0] = "wc"; argv[1] = 0; pipe(p); if(fork() == 0) { close(0); dup(p[0]); close(p[0]); close(p[1]); exec("/bin/wc", argv); } else { close(p[0]); write(p[1], "hello world\n", 12); close(p[1]); } The program must accept the name of a file as a command line argument in argv and pipe the contents of that named file to wc similar to the way the sample code pipes a constant string to wc. Program should compile and work in Linux and xv6.

Write a C program based on the following code:

int p[2];

char *argv[2];

argv[0] = "wc";

argv[1] = 0;

pipe(p);

if(fork() == 0) {

close(0);

dup(p[0]);

close(p[0]);

close(p[1]);

exec("/bin/wc", argv);

} else {

close(p[0]);

write(p[1], "hello world\n", 12);

close(p[1]);

}

The program must accept the name of a file as a command line argument in argv and pipe the contents of that named file to wc similar to the way the sample code pipes a constant string to wc. Program should compile and work in Linux and xv6.
