Add a new property to a struct c++

In C++, you can add a new property to a struct by simply declaring a new member variable inside the struct definition. Here is an example:

struct MyStruct {
    int x;
    int y;
    int z; // new property
};

In this example, we've added a new member variable z to the MyStruct struct.

Alternatively, you can also add a new property to a struct using a constructor or a setter function. For example:

struct MyStruct {
    int x;
    int y;

    MyStruct(int x, int y, int z) : x(x), y(y), z(z) {} // constructor

    void setZ(int z) { this->z = z; } // setter function
};

In this example, we've added a constructor that takes three arguments, including the new property z. We've also added a setter function setZ that allows you to set the value of z after the struct has been created.

Note that in C++, structs are essentially the same as classes, except that structs are public by default and classes are private by default. So, you can also add properties to a struct using a private member variable and a public getter and setter function, just like you would with a class. For example:

struct MyStruct {
    private:
        int z;

    public:
        MyStruct(int x, int y, int z) : x(x), y(y), z(z) {}

        int getZ() { return z; }
        void setZ(int z) { this->z = z; }
};
