Is there any difference between exit(0) & exit(1) ?

Question

I often used exit(0) to exit from program .what's exit(1) & it's use??

Answer 1

You should return from main normally whenever possible instead of using exit().

The value returned by your program can be used when it was launched by another program. A return value of 0 means no error, and a non-zero value means anything you want, and you can use that return value in the main program to do stuff differently.

Needless to say, it's not often used.

Answer 2

exit 0 is successfully exiting the program as intended exit 1 is exit failure or can be a program crashed. I believe in c++ this is return 0; and exit 0 is written in c. but it can be used with c++ if it's what you desire.
