Write a program in C++ to overload the binary operator “+”
(addition).
Program Code for run:
#include
<iostream>
#include
<iomanip>
using
namespace std;
class
Box
{
int

public:
Box
(int l = 0, int w = 0, int h = 0)
{

this->w = w;
this->h
= h;
}
void
operator+( Box b)
{
Box
b1;
b1.l
= this->l + b.l;
b1.w
= this->w + b.w;
b1.h
= this->h + b.h;
