1.头文件:sqstack.h,包含定义顺序栈数据结构的代码、宏定义、要实现算法的函数的声明;
#ifndef SQSTACK_H_INCLUDED#define SQSTACK_H_INCLUDED#define MaxSize 100typedef char ElemType;typedef struct{ ElemType data[MaxSize]; int top; } SqStack; void InitStack(SqStack *&s); void DestroyStack(SqStack *&s); bool StackEmpty(SqStack *s); int StackLength(SqStack *s); bool Push(SqStack *&s,ElemType e); bool Pop(SqStack *&s,ElemType &e); bool GetTop(SqStack *s,ElemType &e); void DispStack(SqStack *s); #endif // SQSTACK_H_INCLUDED

2.源文件:sqstack.cpp,包含实现各种算法的函数的定义
#include <stdio.h>#include <malloc.h>#include "sqstack.h"void InitStack(SqStack *&s){ s=(SqStack *)malloc(sizeof(SqStack)); s->top=-1;}void DestroyStack(SqStack *&s){ free(s);}int StackLength(SqStack *s) { return(s->top+1);}bool StackEmpty(SqStack *s){ return(s->top==-1);}bool Push(SqStack *&s,ElemType e){ if (s->top==MaxSize-1) return false; s->top++; s->data[s->top]=e; return true;}bool Pop(SqStack *&s,ElemType &e){ if (s->top==-1) return false; e=s->data[s->top]; s->top--; return true;}bool GetTop(SqStack *s,ElemType &e){ if (s->top==-1) return false; e=s->data[s->top]; return true;}void DispStack(SqStack *s) { int i; for (i=s->top;i>=0;i--) printf("%c ",s->data[i]); printf("\n");}

3.在同一项目(project)中建立一个源文件(如main.cpp),编制main函数,完成相关的测试工作。 例:
#include <stdio.h>#include "sqstack.h"int main(){ ElemType e; SqStack *s; printf("(1)初始化栈s\n"); InitStack(s); printf("(2)栈为%s\n",(StackEmpty(s)?"空":"非空")); printf("(3)依次进栈元素a,b,c,d,e\n"); Push(s,'a'); Push(s,'b'); Push(s,'c'); Push(s,'d'); Push(s,'e'); printf("(4)栈为%s\n",(StackEmpty(s)?"空":"非空")); printf("(5)栈长度:%d\n",StackLength(s)); printf("(6)从栈顶到栈底元素:");DispStack(s); printf("(7)出栈序列:"); while (!StackEmpty(s)) { Pop(s,e); printf("%c ",e); } printf("\n"); printf("(8)栈为%s\n",(StackEmpty(s)?"空":"非空")); printf("(9)释放栈\n"); DestroyStack(s); return 0;}
