Possible though that earlier compilers required it.

But I always make sure each and every C function (or C# Method) has exactly one return statement.

Interestingly you can call main() from inside your C app, but not in C++.

• There are multiple valid forms of main(...), and implementation-defined arguments are allowed. Allowing calls to it might require too much special case handling between the compiler and linker to ensure a match between the call and the actual implementation.
• Another factor might be runtime initialization that takes place in main()'s prolog.
• Objects declared static could potentially call main() before it had been called for the actual application startup.

int main()
{
  main();
}

void fn

Reaching the } that terminates a function is equivalent to executing a return statement without an expression.
