Arithmetic Operators in C ++

 Arithmetic Operators in C++

Arithmetic operators are used to perform mathematical calculations on numerical values (operands) in C++. These operators include:

 * Addition (+): Adds two operands.

   int a = 5, b = 3;

int sum = a + b; // sum will be 8

 * Subtraction (-): Subtracts the second operand from the first.

   int a = 10, b = 4;

int difference = a - b; // difference will be 6

 * Multiplication (*): Multiplies two operands.

   int a = 2, b = 6;

int product = a * b; // product will be 12

 * Division (/): Divides the first operand by the second.

   int a = 15, b = 3;

int quotient = a / b; // quotient will be 5

 * Modulus (%): Returns the remainder of the division between two operands.

   int a = 7, b = 3;

int remainder = a % b; // remainder will be 1

 * Increment (++): Increases the value of an operand by 1.

   int a = 5;

a++; // a will be 6

 * Decrement (--): Decreases the value of an operand by 1.

   int a = 5;

a--; // a will be 4

Operator Precedence

When multiple operators are used in an expression, the order of evaluation is determined by operator precedence. The order is as follows:

 * Parentheses ()

 * Increment/decrement ++, -- (prefix)

 * Multiplication/division/modulus *, /, %

 * Addition/subtraction +, -

 * Increment/decrement ++, -- (postfix)

Example:

int result = 2 + 3 * 4; // result will be 14 (multiplication has higher precedence)

By understanding arithmetic operators and their precedence, you can effectively perform calculations and manipulate numerical values in your C++ programs.
