一、頭文件:
#ifndef _STACK_LINK_H_ #define _STACK_LINK_H_ struct stack_record; typedef struct stack_record* stack; typedef int elementType; struct link_node; typedef struct link_node node; int IsEmpty(stack s); int IsFull(stack s); stack creatStack(int maxElement); void disposeStack(stack s); void makeEmpty(stack s); void pushElement(elementType x,stack s); elementType Top(stack s); void popElement(stack s); elementType topAndpop(stack s); #define EMPTY 0 #define MINISIZE (5) struct stack_record { int capacity; int size; node *item; }; struct link_node { elementType data; node *next; }; #endif
二、c文件:
#include <stdio.h> #include <stdlib.h> #include "stack_link.h" #define MAXSIZE 100 int IsEmpty(stack s) { return s->size == 0; } int IsFull(stack s) { return s->size == s->capacity; } stack creatStack(int maxElement) { stack s; s = (stack)malloc(sizeof(struct stack_record)); if(s == NULL) { printf("the stack alloca error\n"); exit(-1); } s->capacity = MAXSIZE; s->item = NULL; s->size = 0; return s; } void disposeStack(stack s) { if(s) { if(s->size) makeEmpty(s); free(s); } } void makeEmpty(stack s) { if(s) { while(s->size) { popElement(s); } } } void pushElement(elementType x,stack s) { if(s) { if(IsFull(s)) return; node *ptr = (node *)malloc(sizeof(node)); if(NULL == ptr) { printf("the node alloc is error\n"); exit(-2); } ptr->data = x; ptr->next = s->item; s->item = ptr; s->size++; } } elementType Top(stack s) { if(s) { if(IsEmpty(s)) { printf("the stack is empty\n"); exit(-3); } return s->item->data; } } void popElement(stack s) { if(IsEmpty(s) ) { printf("the stack is empty\n"); exit(-4); } node *ptr = NULL; ptr = s->item->next; free(s->item); s->item = ptr; s->size--; } elementType topAndpop(stack s) { if(s) { if(IsEmpty(s)) { printf("the stack is empty\n"); exit(-5); } elementType x; x = Top(s); popElement(s); return x; } } int main(int argc,char *argv[]) { stack s; s = creatStack(10); int i = 0; elementType x; while(++i <= 10) { pushElement(i,s); printf("the stack size is %d\n",s->size); x = Top(s); printf("the stack top is %d\n",x); } while(s->size) { x = topAndpop(s); printf("the top stack is %d\n",x); sleep(1); } disposeStack(s); return 0; }
三、打印輸出:
