C++ operators are the symbols that operate on values to perform specific mathematical or logical computations on given values. They are the foundation of any programming language.

There are several ways to do this in C++. The simplest one, which has been inherited from the C language, is to precede the expression to be converted by the new type enclosed between parentheses ( ()):

In C++, the addition assignment operator (+=) combines the addition operation with the variable assignment allowing you to increment the value of variable by a specified expression in a concise and efficient way.

All listed operators are in C++ and lacking indication otherwise, in C as well. Some tables include a "In C" column that indicates whether an operator is also in C. Note that C does not support operator overloading.

We recommend reading this tutorial, in the sequence listed in the left menu. C++ is an object oriented language and some concepts may be new. Take breaks when needed, and go over the examples as many times as needed.

They are called compound assignment operators because they combine a regular operator (like +, -, *, etc.) with the assignment operator (=) into one single operator. For example, += is a combination of + and =. Compound assignment operators can also be used in real-life scenarios.

Arithmetic operators in C++ are the basic operators, which are used for basic mathematical or arithmetical operations on operands. These operators are essential for performing calculations and manipulating data within a program.

The following table lists the precedence and associativity of C++ operators. Operators are listed top to bottom, in descending precedence. a, b and c are operands.

When the user-defined postfix operator is called, the value passed in that parameter is always zero, although it may be changed by calling the operator using function call notation (e.g., a.operator++(2) or operator++(a, 2)). The prefix increment and decrement expressions have the form.
