title: What is the significance of return 0 in C and C++?
body: <p>I need the simplest possible answer to this. I have looked up in various sites for the answer. If the inputs to a programme is such that the output is 10, will command return 0 force the programme to return the value 0 instead of 10? I have written simple C programmes on Borland IDE without return 0 and they work fine. </p>
