C PROGRAMMING. MAKE SURE TO USE FORK SYSTEM CALL!!! HAS TO BE in same file

Here is the sequence of events that needs to be implemented: 1. Process A writes to position 1 in memory and then waits until B and C completes 2. Process B writes the string "shared" into memory then signals A & C that it is complete by writing into memory position 1 (note B should wait to write into position 1 until after process A writes into position 1 in memory) 3. Process C writes the string "memory" into memory and then signals A that it is complete by writing into memory position 1 (note C should wait until process B writes into position 1 in memory). 4. Process A is the last one to quit and prints out a "GoodBye" message 'wait 'wait "shared "memory "3" Question 2: Shared Memory (4 pts) Create processes A, B and C from the same file using fork
