Example: Pointers to Structure #include <iostream> using namespace std; struct Distance { int feet; float inch; }; int main() { Distance *ptr, d; ptr = &d; cout << "Enter feet: "; cin >> (*ptr).feet; cout << "Enter inch: "; cin >> (*ptr).inch; cout << "Displaying ...
1506-122 (S) Expecting pointer to struct or union. __你们 大胆 猜 是什么错。。 __ 很尴尬的错误。。就是 结构体指针。 ___只有结构体 指针 可以用 -> 这个符号哦。。 所以 你只要 将 -> 改成 . , 就OK了。。
struct first { char name[15];char password[15];} 对吗？如果是这样，这里存在两个错误：1. 你定义的 first 是一个结构变量，结构变量分量的引用使用原点 first.name 结构指针引用分量才使用箭头 2. 字符型数组不能直接用字符串赋值，只能用函数 strcpy(first.name, "wuqiong");使用字符指针...
