In C++, arithmetic operators are used to perform basic mathematical operations, including addition, subtraction, multiplication, and division. Below are some commonly used arithmetic operators and their usage:

02Compound Operators

In C++, compound operators provide a convenient way to combine assignment operations with another operation. They allow you to assign the result of an operation directly to a variable, thus reducing code redundancy. Compound operators are commonly used for addition (+=), subtraction (-=), multiplication (*=), division (/=), and modulus (%=) operations.

03Relational Operators

In C++, relational operators are used to compare the sizes of two values. These operators return a boolean value (<span>true</span> or <span>false</span>), indicating the result of the comparison. Here are some commonly used relational operators in C++:

04Logical Operators

Logical operations in C++ are a type of operator used to control program flow and conditional judgment logic. The classification of logical operators is as follows:

Logical AND (&&): The result is true when all conditions are true

Logical OR (||): The result is true when at least one condition is true

Logical NOT (!): Negates the condition

05Conditional Operator

The conditional operator (also known as the ternary operator) in C++ is a concise conditional expression that can replace if-else statements. Its basic syntax is as follows:

06Increment and Decrement Operators

Pre-increment ++C [increment before use]

Pre-decrement –C [decrement before use]

Post-increment C++ [use before increment]

Post-decrement C– [use before decrement]
