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...

uintptr是一个无符号的整型,它可以保存一个指针地址,它可以进行指针运算。想取值需要转成unsafe.Pointer后, 需再转到相对应的指针类型。 源代码中的定义如下。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 packagebuiltin//uintptr is an integer type that is large enough to hold the bit pattern of...
struct id { unsigned int id_no; struct name *pname; } record; The variable record has the structure type id. Note that pname is declared as a pointer to another structure type named name. This declaration can appear before the name type is defined.See...
