Operator Overloading does not allow us to alter the meaning of operators when applied to built-in types one of the operands must be an object of a class Operator Overloading does not allow us to define new operator symbols we overload those provided for in the language to have meaning for a new type of data...and there are very specific rules! It is a type of polymorphism in which an operator is overloaded to give user defined meaning to it. Search form. For instance, C++ permits us to add two variables of user-defined types with, the same syntax that is applied to the basic types. <> Operator overloading in C,, C++ provides the ability to add the variables of the user-defined data type that is applied to the built-in data types. /ColorSpace << 17 0 obj >> WhatsApp. –Name of operator function.

In case of input/output operator overloading, left operand will be of types ostream& and istream& Also, when overloading these operators, we must make sure that the functions must be a Non-Member function because left operand is not an object of the class. endobj I hope operator overloading will be helpful for students and beginner to understand basic fundamentals of object-oriented programming.
