Test your C++ programming skills by solving the given puzzle about constructors.

We'll cover the following

Puzzle code

Carefully read the code given below:

Press + to interact
#include <iostream>
struct Degrees
{
    Degrees() : degrees_(0)
    {
        std::cout << "Default constructer invoked\n";
    }
    Degrees(double degrees) : degrees_(degrees)
    {
        std::cout << "Constructed with " << degrees_ << "\n";
    }
    double degrees_;
};
struct Position
{
    Position() : latitude_{1} { longitude_ = Degrees{2}; }
    Degrees latitude_;
    Degrees longitude_;
};
int main()
{
    Position position;
}
