请教一个结构体栈的问题

[yuan697]

typedef struct NODE
{
int x;
int y;
NODE *link;
}*Position,Pos;

typedef struct
{
Position top;
}LinkPosition;


void push(LinkPosition &plposition,int x,int y)
{
Position p;
p = new Pos;
p -> x = x;
p -> y = y;
p -> link = plposition -> top;
plposition -> top = p;
}

我这样写结果出错了,提示type 'LinkPosition' does not have an overloaded member 'operator ->'
请问这该怎么解决呢???

plposition.top

[iu_81]

p -> link = plposition.top;
plposition. top = p;

[yuan697]

用点也是没有用的,提示是一样的

[iu_81]

提示什么？

正如楼上说的,改成
p -> link = plposition.top;
plposition.top = p;
因为你的plposition是LinkPosition 类型的一个引用,而引用在调用成员的时候是用"."而不用"->",那是指针才用的"->"
