Arithmetic Operators in C++

Arithmetic operators in C++ are symbols used to perform mathematical operations on operands. These operators allow you to perform addition, subtraction, multiplication, division, and modulus operations.

Addition (+)

Adds two operands together.

int result = 5 + 3; // result will be 8

Subtraction (-)

Subtracts the right operand from the left operand.

int result = 7 - 4; // result will be 3

Multiplication (*)

Multiplies two operands.

int result = 6 * 2; // result will be 12

Division (/)

Divides the left operand by the right operand. If both operands are integers, the result will be an integer, with any remainder discarded.

int result = 10 / 3; // result will be 3

If you want to get a floating-point result, you can use floating-point operands:

double result = 10.0 / 3.0; // result will be approximately 3.33333

Modulus (%)

Returns the remainder of the division of the left operand by the right operand.

int result = 10 % 3; // result will be 1

These operators can be used with variables, constants, or expressions. They follow the usual rules of precedence and associativity. Additionally, parentheses can be used to enforce a specific order of evaluation.
