Arithmetic Operators in C

Arithmetic operators in C are used to perform basic mathematical calculations. These operators work on numeric operands such as integers and floating-point numbers.

Addition Operator (+)

The addition operator is used to add two operands and return their sum.

Example: int sum = a + b;

Subtraction Operator (-)

The subtraction operator subtracts the second operand from the first operand.

Example: int diff = a - b;

Multiplication Operator (*)

The multiplication operator multiplies two operands.

Example: int product = a * b;

Division Operator (/)

The division operator divides the numerator by the denominator.

Example: int result = a / b;

Note: Integer division truncates decimal values.

Modulus Operator (%)

The modulus operator returns the remainder after division. It works only with integer operands.

Example: int remainder = a % b;

Common Mistakes with Arithmetic Operators

  • Dividing a number by zero causes runtime error
  • Using modulus operator with float values
  • Expecting decimal result from integer division
  • Overflow when result exceeds data type limit
