What are structure constructors in C++?

What are structure constructors in C++?

Structure constructors in C++ are special functions that initialize structure members when an object is created.

Can you give me an example of a structure constructor?

Sure! Here's a simple example:

struct Point {
    int x, y;
    Point(int a, int b) : x(a), y(b) {} // Constructor
};

This constructor initializes the x and y members.

What happens if I don't use a constructor?

If you don't use a constructor, the members of the structure will have undefined values unless you explicitly initialize them.

Are there any default constructors in C++?

Yes, if you don't define any constructor, C++ provides a default constructor that initializes members to default values.
