Write a C program for Linux called pipes.c that does the following: In the main() function, it creates a pipe using the pipe() function, then creates two child processes with fork().
Child 1 redirects stdout to the write end of the pipe and then executes with execlp() the "ps-aux" command.
Child 2 redirects its input from stdin to the read end of the pipe, then it executes the "sort -r -n -k 5" command.
After creating both children, the parent process waits for them to terminate before it can exit.
Note that you may have to create Child 2 first, followed by Child 1. The parent program does the same thing as a shell that runs the command "ps-aux | sort-r-n-k 5". You must use the fork(), pipe(), dup2(), close(), execlp() functions (or other exec() variation).
