Answer 1

1. w 类型float不能存放字符串
2. ''表示单个字符，不能表示字符串
3. 单个字符可以=赋值，字符串不可以

   main()
   {
    int a;
    char w[32] = {0};       //float w;
    printf("请输入一个整数：");
    scanf("%d",&a);
    switch(a<=6)
    {
        case 0:strcpy (w, "Sunday");break;
        case 1:strcpy (w, "Monday");break;
        case 2:strcpy (w, "Tuesday");break;
        case 3:strcpy (w, "wednesday");break;
        case 4:strcpy (w, "Tursday");break;
        case 5:strcpy (w, "Friday");break;
        case 6:strcpy (w, "Saturday");break;
        default :strcpy (w, "None");
    }
    printf("w=%s\n",w);
   }
