* The goal of this assignment is to get familiar with pipelining in C language Write a C program that creates 3 processes (one parent and two children). The processes will relay information to each other in following fashion: - The first process (parent) reads a text file "input.txt" line by line. - The second process reads from the first pipe and reverse letters (Capital to small and small to capital). - The third process reads from the second pipe and outputs to a file e.g. "output.txt". Note that you need to use pipe(), and fork() to create this pipelining assignment. Also, create a text file which contains several text lines. The file will be used as an input for your program..
