在C语言中,求余数可以使用取模运算符`%`来实现。取模运算符返回两个操作数相除后的余数。以下是一些示例代码:
基本求余运算
```c
include int main() { int a = 10; int b = 3; int remainder = a % b; printf("The remainder of %d divided by %d is %d\n", a, b, remainder); return 0; } ``` 输出结果为: ``` The remainder of 10 divided by 3 is 1 ``` ```c include int main() { int dividend, divisor, remainder; printf("请输入被除数:"); scanf("%d", ÷nd); printf("请输入除数:"); scanf("%d", &divisor); remainder = dividend % divisor; printf("余数为:%d\n", remainder); return 0; } ``` 程序会提示用户输入被除数和除数,然后计算并输出余数。 ```c include int main() { int a = -10; int b = 3; int remainder = a % b; printf("The remainder of %d divided by %d is %d\n", a, b, remainder); return 0; } ``` 输出结果为: ``` The remainder of -10 divided by 3 is -1 ``` 求余运算符`%`的两个操作数必须为整数类型,不能为浮点型或其他结构体类型,否则编译器会提示错误。 除数不能为0,否则会产生运行时错误。 余数的符号与被除数相同。 通过以上示例和说明,你可以轻松地在C语言中求余数。输入被除数和除数,计算余数
