Creating a class "Point" having X and Y Axis with getter and setter functions

We have two declare a point class with two Axis X and Y and we have to create/design its getter and setter functions.

As we know that a class has some data members and number functions. So, here we are going to declare two private data members X and Y of integer types. X will be used for the X-axis and Y will be used for the Y-axis.

Now, let's understand what are getter and setter member functions?

Setter functions are those functions which are used to set/assign the values to the variables (class's data members). Here, in the given class, the setter function is setPoint() - it will take the value of X and Y from the main() function and assign it to the private data members X and Y.

Getter functions are those functions which are used to get the values. Here, getX() and getY() are the getter function and they are returning the values of private members X and y respectively.

C++ program to create a class "Point" having X and Y Axis with getter and setter functions

#include <iostream>
using namespace std;

// claas declaration
class point {
private:
    int X, Y;

public:
    //defualt constructor
    point()
    {
        X = 0;
        Y = 0;
    }

    //setter function
    void setPoint(int a, int b)
    {
        X = a;
        Y = b;
    }
    //getter functions
    int getX(void)
    {
        return X;
    }
    int getY(void)
    {
        return Y;
    }
};

//Main function
int main()
{
    //object
    point p1, p2;

    //set points
    p1.setPoint(5, 10);
    p2.setPoint(50, 100);

    //get points
    cout << "p1: " << p1.getX() << " , " << p1.getY() << endl;
    cout << "p1: " << p2.getX() << " , " << p2.getY() << endl;

    return 0;
}

Output

p1: 5 , 10
p1: 50 , 100
