Properties of different architectures

Software architectures are the blueprint of a software system. They consist of all components involved in a system, relations between various components, the environment of operation, and the principle used in designing the software. In other words, software architecture shows the organization of different software structures and helps understand their behavior.

Question

Write a C program that will first create the necessary pipes and
generate the below process tree.
P2
P1
P3
P4
The program works as follows:
Process P2 displays "P2" and asks the user to enter a
positive integer (side) representing the length of a side of
a square. Then, P2 will read this value from the user and
send it to P1.
Afterwards, Process P1 receives the length sent by P2
and sends the length back to Process P3. Then, Process
P1 will wait until the child processes terminate.
Process P3 receives the length sent by P1 and calculates
the area of a square which is equal to (side?) and the
perimeter of a square which is equal to (4 x side) and
then it sends the area of the square and the perimeter of
the square to P4.
Process P4 receives the area of the square and the
perimeter of the square sent by process P3, and displays
"P4" and the area of the square and the perimeter of the
square.
Note that all the values exchanged between processes should be
sent and received using PIPE(S).
After you finish, copy the code and paste it in the Google
Classroom Test Form.
Sample Run:
P2: Enter the length of the side of a square: 2
P4: The area of the square is 4, and the perimeter is 8
