WRITE THIS IN C !!!! ALSO NOTE THE INPUT IS A FILE!!!!!

Design a program using ordinary pipes in which one process sends a string message to a second process, and the second process reverses the case of each character in the message and sends it back to the first process. For example, if the first process sends the message Hi There, the second process will return hI tHERE. This will require using two pipes, one for sending the original message from the first process to the second process, and the other for sending the modified message from the second process to the first process. Your program should take a file name name as input and use it as follows:

name-1.txt: the name of the file that contains the message to be transformed.

name-2.txt: the name of the file that contains the message received by the second process from the first process.

name-3.txt: the name of the file that contains the transformed message sent by the second process to the first process.

name-4.txt: the name of the file that contains the transformed message received by the first process from the second process. You should write your program in C/C++ and it should run on a UNIX/Linux system. You will need to use fork( ) and pipe( ) system calls in this program. You can learn more about these and other related system calls in the man pages.
