user puts in the number of employees but inputs less employees. He terminates the loop
by pressing the ENTER key. How do i do that. I tried strlen,, and even trid atoi but i dont know how to terminated
it. Also when it terminated its just uses that many employees that were entered and outputs the result.
The below method give me garbage. I need the return statment
to give me the count so i can display the results for the employees that were entered.
