may be adding return 0; would be good in future. All the best.

From Wikipedia:
Within functions that define a non-void return type, failure to return a value before control reaches the end of the function results in undefined behaviour (compilers typically provide the means to issue a diagnostic in such a case).^[17] The sole exception to this rule is the main function, which implicitly returns a value of zero.^[18]

Hm... Wikipedia... Is it a new compiler?

A lot of contestants during last 15 years have a lot of trouble because of omission of this ending return. Surely one could enjoy spending his time during contest and found out how present compiler reacts.

But I suppose that such experiments are not real goal for contestants.

There are specific compilers + library suits which does not even allow main to have "int" type (like Keil or WinAVR), but that means nothing.

Quote has a link to standard of language c++. It's a compiler's problem, if it doesn't follow standards.

Compiler's problem would become contestant's problem if he want to rely upon some "standard" but obscure facts, without significant reason to do so. I believe that MSVC and G++ would work well, and none would use Borland. But I do not see what for we need to skip these few characters if it is altogether proper and meaningful that int function should return int value.
