（C语言）简单明了的数组模拟栈+ （C++）数组模拟栈

C语言数据结构中的很多东西都能够通过数组和链表来实现，所以熟练数组和链表是很有必要的。

栈的特点就是先进后出，如图输出。

#include <iostream>
    #include <stdlib.h>
    #include <stdio.h>
    #include <memory.h>//memset库源
    
    using namespace std;
    
    struct Stack
    {
        char space[1024];
        int top;
    };
    
    void init(Stack *s)
    {
        s->top=0;
        memset(s->space,0,1024);
    }
    
    bool Isfull(Stack *s)
    {
        return s->top==1024;
    }
    
    char pop(Stack *s)
    {
        return s->space[--s->top];
    }
    
    void push(Stack *s,char c)
    {
        s->space[s->top++]=c;
    }
    
    int Is_empty(Stack *s)
    {
        if(s->top==0)
            return 1;
        return 0;
    }
    
    int main()
    {
        Stack st;
        init(&st);
        if(!Isfull(&st))
            push(&st,'a');
        if(!Isfull(&st))
            push(&st,'b');
        if(!Isfull(&st))
            push(&st,'c');
        if(!Isfull(&st))
            push(&st,'d');
        if(!Isfull(&st))
            push(&st,'e');
        if(!Isfull(&st))
            push(&st,'f');
    
        while(!Is_empty(&st))
            cout<<pop(&st)<<endl;
        return 0;
    }

如果在纯C下，把cout输出改用printf

#include <iostream>
    #include <memory.h>
    
    using namespace std;
    
    struct Stack
    {
        void init();
        bool isEmpty();
        bool isFull();
        char pop();
        void push(char c);
    private:
        char space[1024];
        int top;
    };
    void Stack::init()
    {
        top=0;
        memset(space,0,1024);
    }
    
    bool Stack::isEmpty()
    {
        return top==0;
    }
    
    bool Stack::isFull()
    {
        return top==1024;
    }
    
    char Stack::pop()
    {
        return space[--top];
    }
    
    void Stack::push(char c)
    {
        space[top++]=c;
    }
    
    int main()
    {
        Stack st;
        st.init();
    
        for(char v='a';!st.isFull()&&v!='z'+1;++v)
        {
            st.push(v);
        }
    
        while(!st.isEmpty())
            cout<<st.pop()<<" ";
        return 0;
    }

下面是 C++链表模拟栈/

#include <iostream>
    #include <memory.h>
    
    using namespace std;
    
    struct Node
    {
        int data;
        struct Node * next;
    };
    
    class List
    {
    public:
        List *createList();
        void insertList(int d);
    
        void traverseList();
    
    private:
        Node * head;
    };
    
    List * List::createList()
    {
        head=new Node;
        head->next = NULL;
    }
    
    void List::insertList(int d)
    {
        Node * cur = new Node;
        cur->data=d;
        cur->next = head->next;
        head->next=cur;
    
    }
    
    void List::traverseList()
    {
        Node * ph = head->next;
        while(ph!=NULL)
        {
            cout<<ph->data<<endl;
            ph = ph->next;
        }
    }
    
    int main()
    {
        List list;
        list.createList();
    
        for(int i=0;i<10;i++)
        {
            list.insertList(i);
        }
    
        list.traverseList();
        return 0;
    }
