C++堆栈类模板实现代码

最近在复习数据结构,涉及到堆栈的实现,通过类模板可以使堆栈的存储数据类型更为灵活,下面是堆栈的实现代码:

#ifndef MYSTACK_H

#define MYSTACK_H

#include <iostream>

using namespace std;

template <typename T>

class MyStack

{

public:

MyStack(int size);

~MyStack();

bool stackEmpty();//判空

bool stackFull();//判满

void clearStack();//清空

int stackLength();//长度

bool push(T elem);//压栈

bool pop(T &elem);//出栈

bool stackTop(T &elem);//返回栈顶

void stackTranverse();//遍历栈

private:

T *m_pStack;//栈指针

int m_iSize;//栈容量

int m_iTop;//栈顶

};

template <typename T>

MyStack<T>::MyStack(int size)

{

m_iSize = size;

m_pStack = new T[m_iSize];

m_iTop = 0;

}

template <typename T>

MyStack<T>::~MyStack()

{

delete m_pStack;

m_pStack = NULL;

}

template <typename T>

bool MyStack<T>::stackEmpty() {//判空

return m_iTop == 0 ? true : false;

}

template <typename T>

bool MyStack<T>::stackFull() {//判满

return m_iTop == m_iSize ? true : false;

}

template <typename T>

int MyStack<T>::stackLength() {//栈长度

return m_iTop;

}

template <typename T>

void MyStack<T>::clearStack() {//清空

m_iTop = 0;

}

template <typename T>

bool MyStack<T>::push(T elem) {//压栈

if (stackFull()) {

return false;

}

else {

m_pStack[m_iTop++] = elem;

return true;

}

}

template <typename T>

bool MyStack<T>::pop(T &elem) {//出栈

if (stackEmpty())

{

return false;

}

else {

elem = m_pStack[--m_iTop];

return true;

}

}

template <typename T>

bool MyStack<T>::stackTop(T &elem) {//返回栈顶元素

if (stackEmpty())

{

return false;

}

else {

elem = m_pStack[m_iTop-1];

return true;

}

}

template <typename T>

void MyStack<T>::stackTranverse() {//遍历栈

int i = 0;

for (i = 0; i < m_iTop; i++) {

cout << m_pStack[i];

}

}

#endif

其中需要注意的是类模板需要在每个函数之前写上模板定义template <typename T>,并且将类名写成MyStack<T>,函数中涉及到类的使用时用T代替即可。

接着我用一个坐标点类Coordinate来做测试:

在Coordinate类中利用函数重载运算符<<实现坐标点的打印

#include <ostream>

using namespace std;

class Coordinate

{

public:

friend ostream& operator<<(ostream &out, Coordinate &coor);

Coordinate(int x=0,int y=0)

{

m_iX = x;

m_iY = y;

}

~Coordinate()

{

}

private:

int m_iX;

int m_iY;

};

ostream& operator<<(ostream &out, Coordinate &coor) {

out << "(" << coor.m_iX << "," << coor.m_iX << ")" << endl;

return out;

}

下面是测试主函数:

#include <iostream>

#include "MyStack.h"

#include "Coordinate.h"

using namespace std;

int main() {

MyStack<Coordinate> *pStack = new MyStack<Coordinate>(5);

pStack->push(Coordinate(3, 5));//坐标点入栈

pStack->push(Coordinate(7, 5));

pStack->push(Coordinate(6, 5));

pStack->push(Coordinate(4, 5));

pStack->push(Coordinate(3, 5));

pStack->stackTranverse();//遍历栈

Coordinate t;

pStack->pop(t);//出栈

cout <<"弹出的t为:"<< t ;

cout << "长度:" << pStack->stackLength();

pStack->clearStack();//清空栈

pStack->stackTranverse();

//delete pStack;

//pStack = NULL;

system("pause");

return 0;

}
