What will be printed as a result of the program?
#include <iostream>
using namespace std;

static int a = 0, b = 3;

int change_a() { return ++a; }
int change_b(int x) { return b+=x; }

void func(int x)
{
	static int aa = change_a();
	static int bb = change_b(x);
}

int main()
{
	func(1); func(3); func(5); func(9);
	cout << a << " " << b;
	return 0;
}
Explanation
The change_a and change_b functions will be called only once from the func function because they initialize static variables and the initialization of static variables is performed only once.
