Assignment description :

Task:

Write a C program that simulates a parallel task execution scenario using process forking. The program should create a specified number of child processes, each performing a unique task. The parent process should wait for all child processes to complete before displaying the final result.

Requirements:

Your program should take an integer input n from the user, where n represents the number of child processes to be created. n should be less than $5.$

Each child process should perform a different task, such as computing the factorial of a number, finding prime numbers in a range, or any computationally intensive operation.

The parent process should display a message before creating $($forking$)$ the child processes.

Each child process should print its own identifier $($PID$)$ and the task it is performing.

After completing their tasks, each child process should print a completion message.

The parent process should wait for all child processes to finish before displaying a final message.

Additional Considerations:

Use the fork$()$ system call to create child processes.

You may use other relevant system calls or functions as needed $($e$.$g$.,$ wait$(),$ exit$()).$

Ensure proper error handling for system calls.

Design the code to guarantee the creation of exactly n children, ensuring that each child executes its intended task. Properly manage the process creation to avoid any unintended duplication or omission of child processes.

Submission Guidelines:

Submit the C source code along with a brief report explaining the design choices and the lessons learned during the implementation. Discuss any challenges encountered and how they were addressed.

Sample output:

$ $./$parallel$\_$execution

Enter the number of child processes to create: $3$

Parent process $($PID: $1234)$ is creating $3$ child processes.

Child $1($PID: $1235)$ is computing the factorial of $5.$

Child $2($PID: $1236)$ is finding prime numbers up to $20.$

Child $3($PID: $1237)$ is performing a custom task.

Child $1($PID: $1235)$ completed its task. Result: $120$

Child $2($PID: $1236)$ completed its task. Result: $235711131719$

Child $3($PID: $1237)$ completed its task. Result: Custom task completed.

All child processes have completed. Parent $($PID: $1234)$ is displaying the final message.
