Arithmetic Operators

Arithmetic operators in C++ are used to perform mathematical calculations on variables and values. They are commonly used in programs for calculations and problem-solving.

What are Arithmetic Operators?

Arithmetic operators are symbols used to perform basic mathematical operations such as:

• Addition
• Subtraction
• Multiplication
• Division
• Modulus

Types of Arithmetic Operators in C++

Operator	Operation
+	Addition
-	Subtraction
*	Multiplication
/	Division
%	Modulus (Remainder)

Addition Operator (+)

Used to add two values.

Example

#include <iostream>
using namespace std;

int main() {
    int a = 10;
    int b = 5;

    cout << a + b;

    return 0;
}

Output

15

Subtraction Operator (-)

Used to subtract one value from another.

Example

cout << 10 - 5;

Multiplication Operator (*)

Used to multiply values.

Example

cout << 4 * 3;

Division Operator (/)

Used to divide values.

Example

cout << 20 / 5;

Modulus Operator (%)

Used to find the remainder after division.

Example

cout << 10 % 3;

Output

1

Complete Example Program

#include <iostream>
using namespace std;

int main() {
    int a = 20;
    int b = 5;

    cout << "Addition: " << a + b << endl;
    cout << "Subtraction: " << a - b << endl;
    cout << "Multiplication: " << a * b << endl;
    cout << "Division: " << a / b << endl;
    cout << "Modulus: " << a % b << endl;

    return 0;
}

Output

Addition: 25
Subtraction: 15
Multiplication: 100
Division: 4
Modulus: 0

Important Points

• Division between integers gives integer result
• Modulus operator works only with integers
• Arithmetic operators are widely used in calculations

Why Arithmetic Operators are Important

They are important because they:

• Perform mathematical calculations
• Help solve programming problems
• Are used in formulas and algorithms
• Support data processing

Real-Life Example

Arithmetic operators are used in:

• Calculating marks
• Finding salary
• Shopping bills
• Banking systems
• Scientific calculations

Conclusion

Arithmetic operators in C++ are essential tools for performing mathematical operations. They help programs process data, solve calculations, and build logical applications efficiently.
