C语言实现链表数据顺序输入输出

C语言实现链表数据顺序输入输出

构建一个链表,用于存放用户输入的数据,一个数据为一个节点,按照输入的先后顺序加到链表中。当用户输入0时结束输入并按输入先后顺序输出数据。

具体实现代码如下:

#include <stdio.h>
#include <stdlib.h>

struct node{
    int n;
    struct node *pNext;
}; 

void main(){
    struct node *pHead = NULL, *pEnd = NULL, *pNode = NULL;
    int i = 1;
    printf("Please input a integer:\n");
    printf("end by inputing 0:");
    do{
        scanf("%d",&i);
        if(i != 0){
            pNode = (struct node *)malloc(sizeof(struct node));
            if(pNode != NULL){
                pNode -> n = i;
                pNode -> pNext = NULL;
                if(pHead == NULL){
                    pHead = pNode;
                    pEnd = pNode;
                }
                else{
                    pEnd -> pNext = pNode;
                    pEnd = pNode;
                }//end of if(pHead == NULL)
            }//end of if(pNode != NULL)
        }//end of if(i == 0)
    }while(i != 0);
    pNode = pHead;
    while(pNode != NULL){
        printf("%d\t", pNode -> n);
        pHead = pNode;
        pNode = pNode -> pNext;
        free(pHead);
    }
    printf("\n");
}

输出结果如下图所示:
