为了堆栈实现

为了堆栈数据结构如下面：

typedef struct
{
	ElemType data[MaxSize];    //栈数据
	int top;                  //栈顶指针
}SqStack;

实现下列函数:

void InitStack(SqStack* &s);    //初始化栈
void DestroyStack(SqStack* &s);  //销毁栈
int StackLength(SqStack* s);  //求栈的长度
int StackEmpty(SqStack* s);  //栈是否为空
int Push(SqStack* &s,ElemType e);  //进栈
int Pop(SqStack* &s,ElemType &e);   //出栈
int GetTop(SqStack* s,ElemType &e); //取栈顶元素
void DispStack(SqStack* s); //输出栈 

详细实现代码:

#include<stdio.h>
#include<stdlib.h>
#include<iostream>
#define ElemType int
#define MaxSize 1000
#define GET_ARRAY_LENGTH(array)  (sizeof(array)/sizeof(array[0]))
using namespace std; 

typedef struct
{
	ElemType data[MaxSize];    //栈数据
	int top;                  //
}SqStack;

void InitStack(SqStack* &s);    //初始化栈
void DestroyStack(SqStack* &s);  //销毁栈
int StackLength(SqStack* s);  //求栈的长度
int StackEmpty(SqStack* s);  //栈是否为空
int Push(SqStack* &s,ElemType e);  //进栈
int Pop(SqStack* &s,ElemType &e);   //出栈
int GetTop(SqStack* s,ElemType &e); //取栈顶元素
void DispStack(SqStack* s); //输出栈 

void InitStack(SqStack* &s){
	s=(SqStack* )malloc(sizeof(SqStack));
	s->top=-1;
}

void DestroySqStack(SqStack* &s){
	free(s);
}

int StackLength(SqStack* s){
	return (s->top+1);
}

int StackEmpty(SqStack* s){
	return (s->top==-1);
}

void DispStack(SqStack* s){
	for(int i=s->top;i>-1;i--)
		cout<<s->data[i]<<" ";
	cout<<endl;
}
int Push(SqStack* &s,ElemType e){
	if(s->top+1==MaxSize)return -1;
	else{
		s->data[s->top+1]=e;
		s->top++;
		return 1;
	}
}

int Pop(SqStack* &s,ElemType &e){
	if(s->top==-1)return -1;
	else{
		e=s->data[s->top];
		s->top--;
		return 1;
	}
} 

int GetTop(SqStack* s,ElemType &e){
	if(s->top==-1)return -1;
	else {
		e=s->data[s->top];
		return 1;
	}
}

int main(){
	int i=0;
	ElemType e;
	SqStack* s=NULL;
	ElemType a[]={3,76,4,25,7,8,2,43,212};
	InitStack(s);
	for(int i=0;i<GET_ARRAY_LENGTH(a);i++){
		Push(s,a[i]);
		DispStack(s);
	}
	GetTop(s,e);
	cout<<e<<" "<<StackLength(s)<<" "<<endl;
	for(int i=0;i<GET_ARRAY_LENGTH(a);i++){
		Pop(s,a[i]);
		DispStack(s);
	}
	return 0;
}

代码执行 结果例如以下:
