Question

Can you print anything in C++, before entering into the main function?

It is interview question in Bloomberg:

Answer :create a global varia

Answer 1

Header file

class A
{
   static A* a;
public:
   A() { cout << "A" ; }
};

Implementation file:

A* A::a = new A;

Well, statics (and not only) are initialized before the call to main.

EDIT

Another one:

bool b = /*(bool)*/printf("before main");

int main()
{
   return 0;
}
