Mis on override märksõna kasutamise eesmärk programmeerimises?

The override keyword in C++ is used to explicitly indicate that a method in a derived class overrides a virtual method of the base class. This helps the compiler verify that the method actually overrides an existing virtual method and to avoid errors, for example, due to typos in the name or signature mismatch.

Example:

struct Base {
    virtual void foo();
};

struct Derived : Base {
    void foo() override; // the compiler will check if foo() overrides a method from Base
};

If a method with override does not match any virtual method in the base class, the compiler will generate an error.
