Write a c++ program. Make sure your program handle all validations, use at least one class.z1,2,3,4 =±x /(±y).

Question

#include <cstdlib>
#include <iostream>
#include <math.h>

using namespace std;
class Coding{
private:
double x , y ;
double z1 , z2 , z3 , z4;
public:
};
void Coding:: display(){
cout << "Enter a value for x \n";
cin >> x;
cout << "Enter a value for y \n";
cin >> y;

if(y == 0){
z1 = (x / y);
z2 = (-x) / (-y);
z3 = (-x) / (y);
z4 = (x) / (-y);

cout<<"The answer for z1 = "<<z1<<" and z2 ="<<z2<<endl;
cout<<"The answer for z3 = "<<z3<<" and z4 ="<<z4<<endl;
}
else{
cout<<"Error! Check Your Values"<<endl;
}
}

int main(){
Coding myCoding;
myCoding.display();
}
