How to use pipes in c++

H

Today we are going to see, how can we use pipes and fork system call for creating multiple processes and handling our work. We are going to implement a use case that will use a fork system call to generate two processes, one will make use of ls command and pass its output to the second child which will display the output of ls with numbering. I am assuming most of you are familiar with at least...
