What does / mean and how to use it in C language

The division operator in C language is /, which is used to calculate the quotient of two operands. It supports integer and floating-point division, with priority higher than addition and subtraction but lower than multiplication and division. Division by 0 produces a runtime error. Integer division discards the fractional part, while floating-point division returns the floating-point quotient.

What does / mean in C language?

/ symbol is represented in C language Division operator.

Usage

/ notation is used to divide two operands and return the quotient. Operands can be integers, floating point numbers, or expressions.

Operation priority

The operation priority of the division operator is higher than addition and subtraction, but lower than multiplication and modulo operations.

Usage Example

int num1 = 10;
int num2 = 5;
int result = num1 / num2; // result 等于 2

In the above example, num1 is divided by num2 and the result is stored in result in.

Dividing by 0

Dividing by 0 is not allowed in C language and will generate a runtime error.

Integer division

When both operands are integers, the division operation returns an integer quotient. The decimal part will be discarded.

int num3 = 11;
int num4 = 3;
int result2 = num3 / num4; // result2 等于 3

Floating-point division

When one or both operands are floating-point numbers, the division operation returns a floating-point quotient.

float num5 = 10.5;
float num6 = 3.5;
float result3 = num5 / num6; // result3 等于 3
