有关链接列表的一些帮助

好吧,我已经更新了不少代码。我遇到了一个新问题,但似乎走上了正确的道路。现在,当我输入数字时,它只是不断地吐出我输入的第一个数字,而不是移动到下一个数字。

主.c

#include <stdio.h>
#include <stdlib.h>
#include <stdbool.h>
#include <cType.h>
#include "list.h"


#define amount 3 

//Prototypes
void printList(LIST* number);

int main(){
    int i;
    int* dataPtr;
    int number;

    LIST* numberList;
    numberList = createList();

    printf("Please enter %d numbers for the linked list\n", amount);

    for(i = 0; i < amount; i++){
          printf("#%d: ", i+1);
          scanf("%d", &number);
          dataPtr = malloc(sizeof(int));
          *dataPtr = number;
          addNode(numberList, dataPtr);
    }
    printList(numberList);
    system("PAUSE");    
    return 0;
}

void printList(LIST* number){
     int* dataPtr;
     while (!emptyList(number)){
           traverse(number,0, (void*)&dataPtr);
           printf("%d\n", *dataPtr);
           addNode(number, dataPtr);
     }
}
