比较简单，代码留一下备用

数组实现：

//栈的顺序存储及实现  
\#include <iostream>  
using namespace std;  
\#define MAXSIZE 100  
class stack  
\{  
private:  
int arrayStack\[MAXSIZE\];  
int top;  
public:  
stack();  
~stack()\{\};  
bool ClearStack();  
bool IsEmpty();  
int GetTop();  
bool Push(int a);  
bool Pop();  
int StackLength();  
void print();  
\};  
  
  
stack::stack()  
\{  
top = -1;  
\}  
bool stack::IsEmpty()  
\{  
return top == -1;  
\}  
int stack::GetTop()  
\{  
if (IsEmpty()) return -1;  
else return arrayStack\[top\];  
\}  
bool stack::ClearStack()  
\{  
if (IsEmpty()) return false;  
else \{  
top = -1;  
return true;  
\}  
\}  
int stack::StackLength()  
\{  
return top + 1;  
\}  
bool stack::Push(int a)  
\{  
if (top == MAXSIZE - 1)  
return false;  
else  
\{  
arrayStack\[++top\] = a;  
\}  
\}  
  
  
bool stack::Pop()  
\{  
if (IsEmpty()) return false;  
else  
\{  
top--;  
return true;  
\}  
\}  
void stack::print()  
\{  
for (int i = 0; i <= top; i++)  
\{  
cout<<arrayStack\[i\]<<" ";  
\}cout<<endl;  
\}  
  
链式存储及实现：

//链栈  
\#include <iostream>  
using namespace std;  
struct Node  
\{  
int val;  
Node \*next;  
\};  
class stack  
\{  
private:  
Node \*top;  
int count;  
public:  
stack();  
~stack()\{\}  
bool Pop();  
void Push(int a);  
int GetTop();  
bool IsEmpty();  
void print();  
\};  
stack::stack()  
\{  
top = NULL;  
int count = 0;  
\}  
void stack::Push(int a)  
\{  
Node \*temp = new Node;  
temp->val = a;  
temp->next = top;  
top = temp;  
count++;  
\}  
bool stack::Pop()  
\{  
if (IsEmpty())  
return false;  
else  
\{  
Node \*temp = top;  
top = top->next;  
delete temp;  
count--;  
return true;  
\}  
\}  
bool stack::IsEmpty()  
\{  
return top == NULL;  
\}  
int stack::GetTop()  
\{  
if (IsEmpty())  
return -1;  
else  
return top->val;  
\}  
void stack::print()  
\{  
Node \*temp = top;  
while (temp)  
\{  
cout<<temp->val<<" ";  
temp = temp->next;  
\}  
cout<<endl;  
\}
