Semaphore ATM program

This program uses semaphores (data type that is used for controlling multiple processes to a common resource in a parallel programming) to simulate a bank account process. It uses four concurrent processes composed of a parent and three children. The customer owns three bank accounts with his wife, savings checking, and vacation accounts. To determine which process runs, the program searches for a random integer assigned to each account, when the random integer is divisible by the assigned account number, the process runs its transactions.
