Exercise 3.2 Display a date

    int date = 0;
    int month = 0;
    int year = 0;

    scanf("%d", &date);//date描述不对，应该是day 
    scanf("%d", &month);
    scanf("%d", &year);
    
    if(date>3 && date<21 || date>23 && date<31)
              printf("%dth", date);//没有换行符 
    else
    printf("%d%s", date, (date == 1?"st":(date == 2?"nd": "rd")));//后面的要加"字符串符号" .2.?:格式记错  3. 赋值符号和等于号记错 switch (month):{
     case month = 1; //月份直接写反
