1. Overload the ‘+’ and ‘-’ operator in this class that by using these operators one should be able to add and subtract the three integers using two objects of this class?
class Nums
{
private:
int x,y,z;
public:
Nums (int,int,int);
Nums ();
Nums operator+ (const Nums& n1, const Nums& n2);
Nums operator-(const Nums& n1, const Nums& n2);
};
Solution:
Nums operator +(const Nums& n1, const Nums& n2) //Addition
{
Nums res;
res.x = n1.x + n2.x;
res.y = n1.y + n2.y;
res.z = n1.z + n2.z;
return res;
}
Nums operator -(const Nums& n1, const Nums& n2) //Subtraction
{
Nums res;
res.x = n1.x - n2.x;
res.y = n1.y - n2.y;
res.z = n1.z - n2.z;
return res;
}
