C++ inheritance 中的运算符是什么意思？

Question

I have been reading up on inheritance in C++ and noticed that

class Car: public Vehicle {
  public:
    string model = "Mustang";
};

You used a ":" operator before the defining the child class, however I couldn't find what this means.

Is it just something we should know to use but not how it works or what it does?

Answer 1

The single colon could also signify class inheritance, if the class declaration is followed by : and a class name, it means the class derives from the class behind the single colon.

class InheritedClass : public BaseClass.
