What is the difference between exit(0) and exit(1) in C?

Question

Can anyone tell me? What is the difference between exit(0) and exit(1) in C language?

Answer 1

exit is a system call used to finish a running process from which it is called. The parameter to exit is used to inform the parent process about the status of child process. So, exit(0) can be used (and often used) to indicate successful execution of a process and exit(1) to flag an error. reference link
