Please code in C

The purpose of this project is to introduce students to the concept of shared memory and the problems that can occur if shared memory is not protected adequately.

In this assignment, you will create 4 processes. Each of these processes will share a variable called "total". Each will increment the variable total by one to 100,000, 200,000, 300,000 and 500,000 respectively. Make sure that only the newly created child calls the function process#()

After all the children have finished, the parent process should release the shared memory and terminate. Use the "wait" function so that the parent knows precisely when each of the children finishes. The parent should print the process id of each child as the child finishes execution. Then it should release shared memory and print "End of Program".

Sample output

From Process 1: counter = 270547.

From Process 2: counter = 347860.

From Process 3: counter = 400001.

From Process 4: counter = 500000.

Child with ID: 2412 has just exited.
