当我更改字符数组时链接列表更改

Question

问题是当第二次我把任何单词q-＆gt; ch在if语句中改为新单词时    ..我希望q成为链表开头的指针

while(true){
    tmp=(list*)malloc(sizeof(list));
    printf("\n put any word:");
    scanf("%s",name);
    printf("\n");
    tmp->ch=name;
        if (i==0)
    {
        q=p=tmp;

    }
    else
    {
        p->nxt=tmp;
        p=tmp;
    }

    printf("when you want to end press y \n");
    scanf(" %c",&c);
    if (c=='Y' || c=='y')
    {
        break;
    }
    i++;
}
