Get set in C++

In C++, get/set are two methods that are used to control access to private class members. They are also known as accessors.

Here is an example to explain how to use get/set in class in C++ :

class Person{
private:
    std::string name;
public:
    void setName(std::string n){name=n;}
    std::string getName() const {return name;}
};

In this example, we have a class Person that contains a private member variable name and two public methods setName and getName. The setName method takes a parameter n and assigns it to name variable, while the getName method returns the name variable.

Now, suppose we want to set and get the name of a Person object. We can do it in the following way:

Person p;
p.setName("John");
std::cout << "Name: " << p.getName() << std::endl;

Using the get/set methods is a good practice while dealing with private class members. It provides a level of abstraction and allows us to control the access to variables in our class.
