Arithmetic Operators in C++

Arithmetic operators are used to perform common mathematical operations in C++. They include addition, subtraction, multiplication, division, and modulus.

Key Topics

List of Arithmetic Operators

The following are the arithmetic operators available in C++:

Operator Description Example
+ Addition a + b
- Subtraction a - b
* Multiplication a * b
/ Division a / b
% Modulus a % b
++ Increment ++a or a++
-- Decrement --a or a--

Examples

Example: Using Arithmetic Operators

#include <iostream>

int main() {
    int a = 15;
    int b = 4;
    
    std::cout << "Addition: " << a + b << std::endl;
    std::cout << "Subtraction: " << a - b << std::endl;
    std::cout << "Multiplication: " << a * b << std::endl;
    std::cout << "Division: " << a / b << std::endl;
    std::cout << "Modulus: " << a % b << std::endl;
    
    int c = 5;
    std::cout << "Increment: " << ++c << std::endl;
    std::cout << "Decrement: " << --c << std::endl;
    
    return 0;
}

Output:

Addition: 19

Subtraction: 11

Multiplication: 60

Division: 3

Modulus: 3

Increment: 6

Decrement: 5

Explanation: The program demonstrates the use of arithmetic operators with variables a, b, and c. Increment and decrement operators modify the value of c by 1.

Key Takeaways

  • Arithmetic operators perform mathematical calculations.
  • Increment (++) and decrement (--) operators increase or decrease a variable by 1.
  • Understanding operator precedence is crucial for complex expressions.
