## Introduction

C++ is a versatile programming language that forms the backbone of many software applications. To write effective C++ code, operators play a very crucial part. These are special symbols that tell the compiler to perform specific mathematical or logical manipulations.

This article will simplify the concept of operators in C++. We'll explore different types of operators, such as arithmetic, relational, and logical operators, among others. After reading this article, you will have a better understanding of how and where different operators should be used.

## Arithmetic Operators

In C++, arithmetic operators are the most basic tools you have for handling numbers. Think of them as the basic operations you would do on a calculator: addition, subtraction, multiplication, division, and finding the remainder. These operators help you perform calculations and manipulate data in your programs.

Let's see the table of arithmetic operators with example:

Operator | Name | Description | Example |
---|---|---|---|

+ | Addition | Adds two operands. | x + y |

- | Subtraction | Subtracts the second operand from the first. | x - y |

* | Multiplication | Multiplies two operands. | x * y |

/ | Division | Divides the first operand by the second. Returns the quotient. | x / y |

% | Modulus | Divides the first operand by the second and returns the remainder. | x % y |

++ | Increment | Increments the operand by 1. Can be used as prefix (++x) or postfix (x++). | ++x or x++ |

-- | Decrement | Decrements the operand by 1. Can be used as prefix (--x) or postfix (x--). | --x or x-- |

+ | Unary plus | Indicates a positive value. Has no effect on the operand. | +x |

- | Unary minus | Negates the operand, changing its sign. | -x |

+= | Addition | assignment Adds the right operand to the left operand and assigns the result to the left operand. | x += y (equivalent to x = x + y) |

-= | Subtraction | assignment Subtracts the right operand from the left operand and assigns the result to the left operand. | x -= y (equivalent to x = x - y) |

*= | Multiplication | assignment Multiplies the left operand by the right operand and assigns the result to the left operand. | x *= y (equivalent to x = x * y) |

/= | Division | assignment Divides the left operand by the right operand and assigns the result (quotient) to the left operand. | x /= y (equivalent to x = x / y) |

%= | Modulus | assignment Divides the left operand by the right operand and assigns the result (remainder) to the left operand. | x %= y (equivalent to x = x % y) |

let's see a basic example of these operators:

Output

```
Addition: 8
Subtraction: 2
Multiplication: 15
Division: 1
Modulus: 2
```

This code defines two integer variables, a and b, and then uses arithmetic operators to perform different calculations. The results are printed to the console, demonstrating how each operator functions.
