Designer Default - it's a designer. free The arguments, not the one on which the comment says "default designer" Where do you have one? ♪ ♪

If you'd at least instead

Number (//double a, double b);// конструктор по умолчанию

It was written.

Number (double a = 0.0, double b = 0.0);

It would be different. ♪ ♪

By the way, use for two. double two new double - that's bullying. It's taking a lot more memory than it's slower... Why would you want that?
