What happens to '0' in c program?

Hello,


I have been wondering for a long time about the return statement in the c-programming. Now consider the following code....





int main()


{


.............


return(0);


}





I would like to know where does the value zero(0) go???





Any function's return statement will return the value to it's calling function. Then what is it for main()???

What happens to '0' in c program?
The return value of main() goes back to the operating system. Most of the time this value is just thrown away (99% of the time under windows).





It might be useful if for example, one program runs another program and wants to know if it was successful or not.





By convention, returning 0 means that your program executed successfully. What values other than 0 mean are really up to you, but odds are that you will never need to use it.





Hope that helped!
Reply:It's returned to the operation system.


When another process is running your program, it's able to get the return value and act accordingly.
