输入一个3位正整数n，分别输出n的个位a、十位b、百位c。下面程序的语句填空应为：（）#include int main( ){ int n,a,b,c;scanf(“%d”,&n);a=____;;b=n/10%10;c=n/100;printf(“a=%d b=%d c=%d”,a,b,c); return 0;} A.n/10 B.a%10 C.n%10 D.b/10 输入一个3位正整数n，分别输出n的个位a、十位b、百位c。下面程序的语句填空应为：（）#include int main( ){ int n,a,b,c;scanf(“%d”,&n);a=____;;b=n/10%10;c=n/100;printf(“a=%d b=%d c=%d”,a,b,c); return 0;} A.n/10 B.a%10 C.n%10 D.b/10 正确答案：C
![设有如下代码： class Base{} public class MyCast extends Base{ static boolean b1=false; static int i = -1; static double d = 10.1; public static void main(String argv[]){ MyCast m = new MyCast(); Base b = new Base(); //Here } } 则在 //Here处插入哪个代码将不出现编译和运行错误。 第七章单元测试 A.d =i; B.m=b; C.b1 =i; D.b=m;](https://zhenti.52daan.com/wp-content/themes/dashscroll/img/thumb-medium.png)
