The Complete Guide to C++ Operators and Expressions

C++ Operators and Expressions

Operators are the building blocks of any programming language. In C++, they are used to build expressions that perform work and modify values. They are also used to assign values to variables, compare values, and perform logical operations. Below is an overview of the different types of operators and expressions available in C++.

Arithmetic Operators

Arithmetic operators, such as + and -, are used to perform basic math operations with numerical values. They are used to add, subtract, multiply, and divide values, and can be used to perform more complex calculations such as exponentiation or modulus.

Relational Operators

Relational operators, such as == and >, are used to compare two values. They are used to determine if one value is greater than, less than, equal to, or not equal to another value.

Logical Operators

Logical operators, such as && and ||, are used to combine two or more relational expressions. They are used to form a compound expression that will evaluate to true or false.

Ternary Operators

Ternary operators, such as ?:, are used to execute different parts of code based on a condition. They are usually used as a shorter alternative to an if-else statement.

Bitwise Operators

Bitwise operators, such as & and |, are used to manipulate individual bits within a value. They are used to perform certain operations on binary numbers or memory addresses, such as setting, clearing, or inverting bits.

Expressions

Expressions are combinations of operators and values that are used to perform a specific operation. They can be simple, such as x + y, or complex, such as (x < y && y > z). Expressions can also use both arithmetic and logical operators to create compound expressions with multiple conditions.

By understanding the different types of C++ operators and expressions, it is easier to write code that performs the desired operations and produces the expected results.
