C++堆栈实现(作业)
已解决: 我一生都无法弄清楚为什么在尝试在这里初始化堆栈时出现错误:
#include "stack.h"
#include "linkList.h"
Stack::Stack() : m_top(0), m_size(0)
{
m_stack = new List(); // cannot assign m_stack this way. How do i initialize here?
}
根据 Intellisense 的语法错误如下:
Error: a value of type List* cannot be assigned to an entity of type List*
堆栈类在这里:
#ifndef stack_H
#define stack_H
#include "linkList.h"
class Stack
{
public:
//
// Constructor to initialize stack data
//
Stack();
//
// functionality to determine if stack is empty
//
bool isEmpty();
//
// methods for pushing data on to stack and for
// popping data from the stack
//
void push(Node* current, int newValue);
void pop();
private:
//
// member data which represent the stack, the top
// of the stack and the size of the stack
//
Node* m_top;
List* m_stack;
unsigned m_size;
};
#endif
我知道 linkList 类可以工作,因为我测试了它前。如果我想创建一个新列表,我所要做的就是:
List* myList = new List();
已解决:现在我遇到了一些令人恼火的链接器错误,我无法弄清楚为什么:

为了确保我的堆栈头文件不与 STL 或其他文件冲突,我将其重命名为 myStack.h(是的,开始笑):
#ifndef myStack_H
#define myStack_H
SOLVED:
I cannot for the life of me figure out why I get an error when trying to initialize the stack here:
#include "stack.h"
#include "linkList.h"
Stack::Stack() : m_top(0), m_size(0)
{
m_stack = new List(); // cannot assign m_stack this way. How do i initialize here?
}
The syntax error according to Intellisense is as follows:
Error: a value of type List* cannot be assigned to an entity of type List*
The stack class is here:
#ifndef stack_H
#define stack_H
#include "linkList.h"
class Stack
{
public:
//
// Constructor to initialize stack data
//
Stack();
//
// functionality to determine if stack is empty
//
bool isEmpty();
//
// methods for pushing data on to stack and for
// popping data from the stack
//
void push(Node* current, int newValue);
void pop();
private:
//
// member data which represent the stack, the top
// of the stack and the size of the stack
//
Node* m_top;
List* m_stack;
unsigned m_size;
};
#endif
I know that the linkList class works because I tested it out before. If I wanted to create a new list, all I have to do is:
List* myList = new List();
SOLVED: Now I am getting some infuriating linker errors, and I cant figure out why:
1>------ Build started: Project: Stack, Configuration: Debug Win32 ------

To make sure my stack header file was not in conflict with STL's or whatever, I renamed it myStack.h (yes, begin laughing):
#ifndef myStack_H
#define myStack_H

此错误:
通常在您的项目设置错误时发生。我猜您正在编写一个控制台应用程序,但您选择了除控制台应用程序之外的其他项目作为项目类型。
This error :
Usually happens when your project is wrongly setup. I guess that you are writing a console app but you have selected as type of project something else than a console app.
此链接器错误
意味着链接器找不到 main() 函数。您正在尝试创建一个可执行文件,因此您必须有一个 main()。
另外,您似乎已将原来的问题编辑为其他问题。这非常令人困惑,因为问题和答案/评论不再匹配。如果您遇到其他问题,请开始一个新问题。
This linker error
means that the linker can't find a main() function. You're trying to make an executable, so you have to have a main().
Also, it appears you've edited your original question to now be something else. That's extremely confusing because the question and answers/comments no longer match. Start a new question if you run into another issue.
