Question

Please write in C++ and run in linux.

This assignment is about fork(), exec(), and wait() system calls, and commandline arguments.

Write two C++ programs, to be named parent.cc and child.cc and compiled into executable parent and child, respectively that, when run, will work as follows:

parent

takes in a list of gender-name pairs from the commandline arguments
creates as many child processes as there are in the gender-name pairs and passes to each child process a child number and a gender-name pair
waits for all child processes to terminate
outputs “All child processes terminated. Parent exits.” And terminates.

child

receives a child number and one gender-name pair arguments from parent
outputs “Child # x, a boy (or girl), name xxxxxx.”
Note: content of output depends on data received from parent

Sample run

To invoke the execution:

>parent girl Nancy boy Mark boy Joseph

parent process does the following:

outputs “I have 3 children.” -- Note: the number 3 comes from the number of gender-name pairs in the commandline arguments
creates 3 child processes, and have each execute child and passes to it an integer that represents the child number and one gender-name pair arguments
waits for all child processes to terminate, then
outputs “All child processes terminated. Parent exits.”

Output from child processes

From first child process:

Child # 1: I am a girl, and my name is Nancy.

From second child process:

Child # 2, I am a boy, and my name is Mark.

From third child process:

Child # 3, I am a boy, and my name is Joseph.

Output from parent process

All child processes terminated. Parent exits.

please give: the source programs parent.cc and child.cc, a screenshot that shows successful compile of both programs as well as a successful run.
