3. Write a program to demonstrate Operator overloading.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace program
{
 class OpOver
{
int x, y, z; // 3-D coordinates
public OpOver() { x = y = z = 0; }
public OpOver(int i, int j, int k) { x = i; y = j; z = k; }
// Overload binary + for object + object.
public static OpOver operator +(OpOver op1, OpOver op2)
{
OpOver result = new OpOver();
 /* This adds together the coordinates of the two points  and returns the result. */
result.x = op1.x + op2.x;
result.y = op1.y + op2.y;
result.z = op1.z + op2.z;
return result;
}
// Overload binary + for object + int.
public static OpOver operator +(OpOver op1, int op2)
{
OpOver result = new OpOver();
result.x = op1.x + op2;
result.y = op1.y + op2;
result.z = op1.z + op2;
return result;
}
// Show X, Y, Z coordinates.
public void show()
{
Console.WriteLine(x + ", " + y + ", " + z);
}
}
public class Prog3
{
public static void Main()
{
OpOver a = new OpOver(1, 2, 3);
OpOver b = new OpOver(10, 10, 10);
OpOver c = new OpOver();
Console.Write("Here is a: ");
a.show();
Console.WriteLine();
Console.Write("Here is b: ");
b.show();
Console.WriteLine();
c = a + b; // object + object
Console.Write("Result of a + b: ");
c.show();
Console.WriteLine();
c = b + 10; // object + int
Console.Write("Result of b + 10: ");
c.show();
Console.Read();
}
}
