Let’s see the Binary Operator Overloading in C++ (OOP). Before this we have studied about unary operator overloading and assignment operator overloading.
Sum of two number – Binary Operator Overloading C++
#include <iostream>
using namespace std;
class Sum_T4Tutorials
{
public:
int number;
//constructor
Sum_T4Tutorials()
{
number = 0;
}
//constructor
Sum_T4Tutorials(int n)
{
number = n;
}
// Overloading (+) operator to perform
// addition of two distance object
//using binary operator Overloading
Sum_T4Tutorials operator+(Sum_T4Tutorials formal_parameter) // Call by value
{
// Create an object to return
Sum_T4Tutorials Object3;
// Perform addition of number and inches
Object3.number = number + formal_parameter.number;
// Return the resulting object
return Object3;
}
};
int main()
{
Sum_T4Tutorials Object1(3);
Sum_T4Tutorials Object2(6);
Sum_T4Tutorials Object3;
//Use overloaded operator
Object3 = Object1 + Object2;
cout << "Sum of Number & Inches is: " << Object3.number << endl;
return 0;
}
Output
Sum of Number & Inches is: 9
Addition of Feet and inches – Binary Operator Overloading C++
#include <iostream>
using namespace std;
class T4Tutorials_Height
{
public:
int feet, inches;
//constrcutor
T4Tutorials_Height()
{
//as we know that when we want to store sum of numbers, then
//the variable is initialized with 0.
feet = 0;
inches = 0;
}
//constrcutor
T4Tutorials_Height(int f, int i)
{
feet = f;
inches = i;
}
// Overloading of (+) operator to perform addition
// on two object using binary operator.
T4Tutorials_Height operator+(T4Tutorials_Height formal_parameter) // Call by value
{
// Create an object to return
T4Tutorials_Height h3;
// Perform addition of feet and incheses
h3.feet = feet + formal_parameter.feet;
h3.inches = inches + formal_parameter.inches;
// Return the resulting object
return h3;
}
};
int main()
{
T4Tutorials_Height h1(5, 2);
T4Tutorials_Height h2(5, 4);
T4Tutorials_Height h3;
//Use overloaded operator
h3 = h1 + h2;
cout << "Sum of Feet & Inches: " << h3.feet << "'" << h3.inches << endl;
return 0;
}
Output
Sum of Feet & Inches: 10, 6
