How to Overload the Multiplication Operator in C++?

// C++ Program to implement overload * operator without
// using friend function

#include <iostream>
using namespace std;

class Vector {
    int x, y, z;

public:
    Vector(int x, int y, int z)
    {
        this->x = x;
        this->y = y;
        this->z = z;
    }

    void getVector()
    {
        cout << x << "i" << showpos << y << "j" << z
             << "k\n"
             << noshowpos;
    }

    // Overloading * operator to perform cross product of
    // two vectors, the left operand is *this object
    Vector operator*(Vector const& v)
    {
        int x = (this->y * v.z) - (this->z * v.y);
        int y = (this->z * v.x) - (this->x * v.z);
        int z = (this->x * v.y) - (this->y * v.x);
        return Vector(x, y, z);
    }
};

// driver code
int main()
{
    Vector v1(2, -3, 7), v2(4, 2, -2);
    cout << "Vector 1: ";
    v1.getVector();
    cout << "Vector 2: ";
    v2.getVector();

    // multiplying two vector
    Vector v3 = v1 * v2; // Calling Operator function
    cout << "Vector 3: ";
    v3.getVector();
}
