How to calculate remainder in C language

The method of finding the remainder in C language is to use the % modulo operator, and the syntax is result = expression1 % expression2, where result is the remainder, expression1 is the dividend, and expression2 is the divisor. The calculation consists of dividing expression1 by expression2 and storing the remainder in result. For example, finding the remainder when 10 is divided by 3 is 1.

How to find the remainder in C language

In C language, you can use % to find the remainder (modulo arithmetic) operator. The syntax is as follows:

<code>result = expression1 % expression2;</code>

where:

• result is the remainder
• expression1 is the dividend
• expression2 is the divisor

Calculation steps:

1. Divide expression1 by expression2, get the quotient and remainder.
2. resultStorage remainder.

Example:

<code class="c">int x = 10;
int y = 3;
int remainder = x % y;

printf("余数是：%d\n", remainder);</code>

Output:

<code>余数是：1</code>

Note:

The

• % operator can only be used with integers.
• If the divisor is 0, a runtime error will occur.
• The remainder of a negative number may be negative, depending on the underlying hardware implementation.
