第33题: [单项选择]以下程序的输出结果是( )。 #include<stdio.h> struct st int x; int *y; *p; int dt[4] = 10,20,30,40 ; struct st aa[4]= 50,&dt[0],60,&dt[0],60,&dt[0],60,&dt[0]; main( ) p=aa; printf("%d/n",++(p->x));
A. 10 B. 11 C. 51 D. 60 参考答案:C 答案解析:[解析] 由于数组名保存了数组的首地址,即数组中第一个元素的地址,执行p=aa;后,p指向aa[0],p->x相当于aa[0].x,也就是50,经过自增运算后,显示结果为51。
