The parent process does the following:

a. compute the summary of all the even number from 1, 2, .. 1000, and output this summary;

b. wait for the termination of the child process CP, then terminate;

The child process does the following:

a. compute the summary of all the odd number from 1, 2, .. 1000, and output this summary;
