Visual Studio Strange Behavior

Question

I am writing C ++ code in visual studio 2010 as an example for my junior that looks like

#include <iostream> using namespace std; int main() { cout<< "How are Your"; } 

I did not understand how this program builds and runs without a return statement, if anyone can explain this to me?

Answer 1

Without a return statement, the main function uses return 0; by default return 0;

§ 3.6.1

The return statement basically has the effect of exiting the main function (destroying any objects with automatic storage time) and calling std :: exit with the return value as an argument. If the control reaches the end of main without colliding with the return statement, the effect is that from the execution return 0;
