돌려 봤는데 에러 안나는데요?

• 코드

#include <iostream>

using namespace std;

class Vector2
{
public:
    Vector2(float _x = 0.0f, float _y = 0.0f) : x(_x), y(_y) {}
    float Magnitude() { return (float)sqrt(x * x + y * y); }
private:
    float x{ 0 };
    float y{ 0 };
};

int main()
{
    Vector2 a;
    Vector2 b{ 3,-3 };
    Vector2 c{ numeric_limits<float>::max(),numeric_limits<float>::max() };

    cout << a.Magnitude() << '\n';
    cout << b.Magnitude() << '\n';
    cout << c.Magnitude() << '\n';
}
