C語言裡面,這個符號(->)是什,怎使用?
這是結構體指針中的一個符號,給你寫個程序解釋一下吧,例如:
#include<stdio.h>
struct STU //定義一個結構體
{
int num;
}stu;
int main()
{
struct STU *p; //定義一個結構體指針
p=stu; //p指向stu這個結構體變量
stu.num=100; //給結構體成員num附個初值
printf("%d",p->num); //輸出stu中的num的值
return;
}
看到了吧,->的作法就是在引用結構體中的變量!!
形式如:p->結構體成員(如p->num)
他的作用相當於stu.num或(*p).num
不知道這樣解釋你明不明白、、、、、不懂了call我,O(∩_∩)O~
望采納。
