# C++ Binary Operator Overloading
[ C++ Overloading Operators and Functions](#)
Binary operators require two operands. Below are examples of binary operators. The commonly used addition operator (+), subtraction operator (-), multiplication operator (*), and division operator (/) are all binary operators. Just like the addition (+) operator.
The following example demonstrates how to overload the addition operator (+). Similarly, you can try overloading the subtraction operator (-) and division operator (/).
## Example
```cpp
#include
using namespace std;
class Box{
double length; // Length
double breadth; // Width
double height; // Height
public:
double getVolume(void){
return length * breadth * height;
}
void setLength(double len){
length = len;
}
void setBreadth(double bre){
breadth = bre;
}
void setHeight(double hei){
height = hei;
}
// Overload + operator to add two Box objects.
Box operator+(const Box& b){
Box box;
box.length = this->length + b.length;
box.breadth = this->breadth + b.breadth;
box.height = this->height + b.height;
return box;
}
};
// Main function of the program
int main(){
Box Box1; // Declare Box1 of type Box
Box Box2; // Declare Box2 of type Box
Box Box3; // Declare Box3 of type Box
double volume = 0.0; // Store the volume in this variable
// box 1 details
Box1.setLength(6.0);
Box1.setBreadth(7.0);
Box1.setHeight(5.0);
// box 2 details
Box2.setLength(12.0);
Box2.setBreadth(13.0);
Box2.setHeight(10.0);
// volume of box 1
volume = Box1.getVolume();
cout << "Volume of Box1 : " << volume <<endl;
// volume of box 2
volume = Box2.getVolume();
cout << "Volume of Box2 : " << volume <<endl;
// Add two object as follows:
Box3 = Box1 + Box2;
// volume of box 3
volume = Box3.getVolume();
cout << "Volume of Box3 : " << volume <<endl;
return 0;
}
When the above code is compiled and executed, it produces the following result:
Volume of Box1 : 210
Volume of Box2 : 1560
Volume of Box3 : 1770
