我想弄清楚鏈表，我試圖做一個鏈表，每個節點有兩個項目，但我不能讓它打印正確，我不是確定我做錯了什麼。學習鏈接列表C
這裏是我的代碼：
#include <stdio.h>
#include <stdlib.h>
#include <ctype.h>
#include <string.h>
struct node
{
int num;
char word[30];
struct node *next;
};
int main(void)
{
struct node *learn = NULL;
struct node *temp;
struct node *temp1, *p;
int q, i = 0;
char word1[30];
while (i != 7)
{
printf("Enter a number: ");
scanf("%d", &q);
temp = (struct node *) malloc(sizeof(struct node));
temp->num = q;
temp->next = NULL;
temp1 = p = learn;
while (temp1 != NULL)
{
p = temp1;
temp1 = temp1->next;
}
if (p != NULL)
p->next = temp;
else
learn = temp;
i++;
}
i = 0;
while (i != 7)
{
if (i == 0)
{
int c;
do
{
c = getchar();
} while (c != '\n' && c != EOF);
}
printf("\nEnter a word: ");
fgets(word1, 30, stdin);
temp = (struct node*)malloc(sizeof(struct node));
strcpy(temp->word, word1);
temp->next = NULL;
temp1 = p = learn;
while (temp1 != NULL)
{
p = temp1;
temp1 = temp1->next;
}
if (p != NULL)
p->next = temp;
else
learn = temp;
i++;
}
while (learn != NULL)
{
printf("%d\n", learn->num);
learn = learn->next;
}
while (learn != NULL)
{
printf("%s", learn->word);
learn = learn->next;
}
}
這是我輸入：
Enter a number: 1
Enter a number: 2
Enter a number: 3
Enter a number: 4
Enter a number: 5
Enter a number: 6
Enter a number: 7
輸入一個單詞：一個
輸入一個單詞：乙
輸入一個單詞：c
En之三一句話：d
輸入一個單詞：電子
輸入一個單詞：F
輸入一個單詞：摹
這裏是我所得到的：

我知道我做錯了什麼，我只是不知道。
