What will be the output of the following C++ code?

#include <iostream>
using namespace std;
void func(int a, bool flag = true)
{
    if (flag == true ) 
    {
        cout << "Flag is true. a = " << a;
    }
    else 
    {
        cout << "Flag is false. a = " << a;
    }
}
int main()
{
    func(200, false);
    return 0;
}
