Example from python:

# Python Program illustrate how  
# to overload an binary + operator 
class A: 
    def __init__(self, a): 
        self.a = a 
    # adding two objects  
    def __add__(self, o): 
        return self.a + o.a  
ob1 = A(1) 
ob2 = A(2) 
ob3 = A("Geeks") 
ob4 = A("For") 
print(ob1 + ob2) 
print(ob3 + ob4)
