Operator Overloading in C++ - GeeksforGeeks

C++ Operator Overloading. C++ has the ability to provide the operators with a special meaning for a data type, this ability is known as operator overloading. Operator overloading is a compile-time polymorphism. For example, we can overload an operator '+' in a class like String so that we can concatenate two strings by just using +.

Unit-IV Operator Overloading and Type Conversions

Operator Overloading and Type Conversions INTRODUCTION Operator overloading is one of the many exciting features of C++ language. C++ permits us to add two variables of user-defined types with the same syntax that is applied to the basic types. This means that C++ has the ability to provide the operators with a special meaning for a data type.

Canonical implementations. Besides the restrictions above, the language puts no other constraints on what the overloaded operators do, or on the return type (it does not participate in overload resolution), but in general, overloaded operators are expected to behave as similar as possible to the built-in operators: operator + is expected to add, rather than multiply its arguments, operator ...

7.4 Type Conversion and Operator Overloading - Virginia Tech

To remove this duplication a type conversion is defined that converts an "int" to an "X" and a single overloading for the case "X + X" is provided. Thus, both "int + X" and "X + int" are converted to the single case "X + X". An example of manipulating colors will be used to illustrate the use of type conversion and operator overloading.

Types of Operator Overloading in C++ - GeeksforGeeks

Explanation: In the above program, it shows that no argument is passed and no return_type value is returned, because the unary operator works on a single operand. (-) operator changes the functionality to its member function. Note: d2 = -d1 will not work, because operator-() does not return any value. 2. Overloading Binary Operator. In the binary operator overloading function, there should be ...

[#12] – Operator Overloading and Type Conversion – Questions

Conversion from class type to basic data type – This is performed by overloading the typecast operator conversion function in the class. Conversion from one class type to another class type – This is performed either by defining a single parameter constructor in the destination object’s class or by defining an overloaded typecast operator conversion function in the source object’s class.

Type conversions . When constants and variables of different types are mixed in an expression, complier applies rules of automatic type conversion s. The assignment operation also causes automatic type conversion. The type of data on right of an assignment operator is automatically converted to the type of variable on left.
