*++p='E';
printf("%s",p);
A.-5
B.25
C.-1
D.1
A.12345

D.5432
A.编译失败
B.编译通过,没有结果输出
C.输出:除法正常运行
D.输出:除数不能为0
A.<"hello",1,1>、<"hadoop",1>和<"world",1>
B.<"hello",2>、<"hadoop",1>和<"world",1>
C.<"hello",<1,1>>、<"hadoop",1>和<"world",1>
D.<"hello",1>、<"hello",1>、<"hadoop",1>和<"world",1>
下面程序的功能是:根据输入的整数x和n,利用函数fact实现求。 例如:输入:2,3 输出=8 请在程序中的横线上填入正确的内容,将程序补充完整。 /* c7-1.c 利用函数fact实现求x的n次方*/ #include "stdio.h" int main() { long int fact(long x,long n) ; /*声明fact函数*/ long int x ; long int n; printf("please enter X and N(>=0): "); scanf("%ld,%ld", &x, &n ); printf("%ld,%ld=%ld",x,n, (1) ); /*调用fact函数 */ return 0; } long int fact(long int x, long int n) /*定义fact函数求xn */ { long int i,s; (2) ; /*求累积变量的初始化*/ if (n= =0) return 0; for(i=1; i<=n; i++) *用循环实现xn* s="s*x;" (3) ; *返回结果xn*>
