C++ 顺序栈 实现代码

C++中的顺序栈类是一种常用的数据结构类型,它使用数组来实现先进后出的栈结构。下面是C++顺序栈类的实现代码。


#include<iostream>

using namespace std;

const int MaxSize=50;

class SeqStack{

  private:

    int data[MaxSize];

    int top; //栈顶指针

  public:

    SeqStack(); //初始化顺序栈

    ~SeqStack(); //销毁顺序栈

    bool empty(); //判断顺序栈是否为空

    bool full(); //判断顺序栈是否满

    void push(int x); //插入元素到顺序栈

    int pop(); //从顺序栈中删除元素并返回其值

    int gettop(); //获取栈顶元素的值

};

SeqStack::SeqStack()

  top=-1;

SeqStack::~SeqStack(){}

bool SeqStack::empty(){

  if(top==-1)

    return true;

  else

    return false;

}

bool SeqStack::full(){

  if(top==MaxSize-1)

    return true;

  else

    return false;

}

void SeqStack::push(int x){

  if(full())

    cout<<"Stack is full!"<<endl;

  else{

    top++;

    data[top]=x;

    cout<<"Push element "<<x<<" into stack!"<<endl;

  }

}

int SeqStack::pop(){

  if(empty())

    cout<<"Stack is empty!"<<endl;

    return 0;

  

  else{

    int x=data[top];

    top--;

    cout<<"Pop element "<<x<<" from stack!"<<endl;

    return x;

  }

}

int SeqStack::gettop(){

  if(empty())

    cout<<"Stack is empty!"<<endl;

    return 0;

  

  else{

    cout<<"The top element is "<<data[top]<<"."<<endl;

    return data[top];

  }

}

int main(){

  SeqStack stack;

  int choice=0;

  while(true){

    cout<<"====== C++ Sequential Stack ======"<<endl;

    cout<<"1. Push "<<endl;

    cout<<"2. Pop "<<endl;

    cout<<"3. Get top "<<endl;

    cout<<"4. Exit "<<endl;

    cout<<"=================================="<<endl;

    cout<<"Please choose the operation you want to perform: ";

    cin>>choice;

    switch(choice){

      case 1: { //插入元素到顺序栈

        int x;

        cout<<"Please enter the element to be pushed: ";

        cin>>x;

        stack.push(x);

        break;

      }

      case 2: { //从顺序栈中删除元素并返回其值

        stack.pop();

        break;

      }

      case 3: { //获取栈顶元素的值

        stack.gettop();

        break;

      }

      case 4: { //结束程序

        cout<<"Exiting. Goodbye!"<<endl;

        exit(0);

      }

      default:

        cout<<"Invalid choice! Please enter a valid choice."<<endl;

    }

  }

  return 0;

}

以上是C++顺序栈类的实现代码,使用该代码可以方便地实现顺序栈的各种基本操作,包括插入元素、删除元素和获取栈顶元素的值等。在实际应用中,顺序栈类可以作为一种常用的数据结构类型,用于解决各种问题。
