Study Notes
Operator Overloading in C++
- In C++, the
operator++keyword is used to overload the increment (++) operator.
Overloading the Increment Operator
- When
c1 = ++c2;is written, the overridden++operator is called onc2first, and then the result is assigned toc1. - The prefix increment operator (
++) has a higher precedence than the assignment operator (=), so the increment operation is performed before the assignment.
Syntax of Overloaded ++ Operator
- The
intin the parentheses of the overloaded++operator is a return type, indicating that the operator returns an integer value.
Overloading the Addition Operator
- The overloaded
+operator in C++ is used to add two objects, allowing for custom operations to be performed when combining objects.
Purpose of Operator Overloading
- The purpose of operator overloading in C++ is to allow objects to be manipulated using operators in a more intuitive and natural way, similar to built-in data types.
- It enables developers to create objects that behave like primitive data types, making the code more readable and easier to understand.
