如何在 C 语言中判断奇偶数

判断步骤:

判断奇偶数最简单的方法是使用取模运算(%)。

代码片段:

<code class="c">#include <stdio.h>

int main() {
    int number;

    printf("输入一个整数:");
    scanf("%d", &number);

    if (number % 2 == 0) {
        printf("%d 是偶数\n", number);
    } else {
        printf("%d 是奇数\n", number);
    }

    return 0;
}</code>

详细解释:

  • 取模运算 (number % 2):它计算除以 2 后的余数。
  • 如果余数为 0,则表示该数可以被 2 整除,因此是偶数。
  • 如果余数不为 0,则表示该数不能被 2 整除,因此是奇数。

示例用法:

如果输入数字 7,代码将输出:

<code>输入一个整数:7
7 是奇数</code>
