Write a C program that creates two children, and connects the standard output of one to the standard input of the other using a pipe.
The child commands to run are specified on the command line.
Use pipe(), fork(), dup2(), close(), execlp(), and wait() system calls.
The parent process should wait for both children to complete
(i.e. wait(0); wait(0);) before exiting.
Sample runs:
$ make
gcc -Wall -o pipe pipe.c
$ ls
Makefile pipe pipe.c
$ ls | cat
Makefile
pipe
pipe.c
$ ls | wc
3 3 21
$ ./pipe ls wc
3 3 21
$ ./pipe date cat

Programs must compile with no warnings or errors using: gcc -Wall
Each source file must start with a comment containing your name and a description.
