C++ -- How to overload operator+=? - Stack Overflow

Given the following code snippet, Num(int iNumber = 0) : m_iNumber(iNumber) {} Num operator+=(const Num& rhs) this->m_iNumber = (this->m_iNumber + rhs.m_iNumber); return *this; int m_iNumber; Num a(10); Num b(100); b += a; return 0; I would like to know how to correctly overload the operator+=.

Operator Overloading in C++ - GeeksforGeeks

in C++, Operator overloading is a compile-time polymorphism. It is an idea of giving special meaning to an existing operator in C++ without changing its original meaning. In this article, we will further discuss about operator overloading in C++ with examples and see which operators we can or cannot overload in C++. C++ Operator Overloading.

operator overloading - cppreference.com

Customizes the C++ operators for operands of user-defined types. 1) An overloaded punctuation operator. 2) An allocation function. 3) A deallocation function. 4) An overloaded co_await operator for use in co_await expressions. The behaviors of non-punctuation operators are described in their own respective pages.

Overloading the << Operator for Your Own Classes

Output streams use the insertion (<<) operator for standard types. You can also overload the << operator for your own classes. The write function example showed the use of a Date structure. A date is an ideal candidate for a C++ class in which the data members (month, day, and year) are hidden from view.

C++ Operator Overloading (With Examples) - Programiz

In this case, we can define the behavior of the + operator to work with objects as well. This concept of defining operators to work with objects and structure variables is known as operator overloading. The syntax for overloading an operator is similar to that of function with the addition of the operator keyword followed by the operator symbol.

Overloading stream insertion (<>) operators in C++

In C++, stream insertion operator "<<" is used for output and extraction operator ">>" is used for input. We must know the following things before we start overloading these operators. 2) These operators must be overloaded as a global function. And if we want to allow them to access private data members of the class, we must make them friend.

Operator Overloading | Microsoft Learn

For example, to overload the addition operator, you define a function called operator+. Similarly, to overload the addition/assignment operator, +=, define a function called operator+=. 1 Two versions of the unary increment and decrement operators exist: preincrement and postincrement.

Operator Overloading

By overloading standard operators on a class, you can exploit the intuition of the users of that class. This lets users program in the language of the problem domain rather than in the language of the machine. The ultimate goal is to reduce both the learning curve and the defect rate. Here are a few of the many examples of operator overloading:

Operator Overloading in Programming - GeeksforGeeks

Operator Overloading is a way to redefine the behavior of existing operators (like +, -, *, /) for user-defined types. We can specify how operators should behave when they are applied to user-defined data types or objects, providing a way to implement operations that are relevant to those objects.

What are the basic rules and idioms for operator overloading?

Here's an example of the syntax: // Overloaded call operator. int operator()(const std::string& y) { return /* ... */;
