What is fork programming?
Forking is to take the source code from an open source software program and develop an entirely new program. Forking is often the result of a deadlock in an open source project that is so insurmountable that all work stops. In this context, a fork is a process that generates a copy of itself.
How many processes does a fork create?

What happens when you fork a process in program 2?
When you fork the process in “Program 2”, the child processes inherits every part of the parent process, including the unflushed output buffer. This effectively copies the unflushed buffer to each child process. When the process terminates, the buffers are flushed.
