What will this output?

What will this program output?
Good luck, you'll need it!

#include <iostream>
using namespace std;

int main() {
class c {
public:
c() {
void f();
f();
}
};

c my_c();
}

void f() {
cout << "VALID C++" << endl;
}

The answer is absolutely nothing because c my_c(); is a fucking function declaration.

Completely missed the point "you fucking moron". So what? I don't see anyone complaining that matching regular expressions is hard...!

That's why "thread" is in quotes. Coroutines would be far better for this than actual threads.

It's not possible to be better than linear since the whole program needs to be parsed. Actual multithreading will at best improve performance by a constant factor.
