c语言入门经典（美。霍顿）习题：输入日月年，输出日月年。输出格式为：例如输入12，12，2003，输入12th，December，2003.
大家看看有我这么编程的么。
有好多错啊，有没有更好的算法。
#include<stdio.h>
int main(void)
{
     int   year;
     char month,date;
     scanf("%c%c%d",&date,&month,&year);
     if(date=='1')
        date='1st';
     if(date=='2')
        date='2nd';
     if(date=='3')
        date='3rd';
     if(date=='4')
        date='4th';
     if(date=='5')
        date='5th';
     if(date=='6')
        date='6th';
     if(date=='7')
        date='7th';
     if(date=='8')
        date='8th';
     if(date=='9')
        date='9th';
     if(date=='10')
        date='10th';
     if(date=='11')

     default:

}

真强，言简意赅。要是让霍顿知道了，他得多高兴啊。

他们给出的答案是书上的原题，呵呵。书上确实是那么要求的（1st,2nd,3rd,11st,12nd,13rd,21st,22nd,23rd,31st,其余是th），也许他们以前都做过。也许。。。。。。。。


但是英语里面应该除了1，2，3其余都是th吧

为什么是：char mon[12][10]={"January","February","March","April","May","June","July","August","September","October","November","December"};
    char da[4][3]={"st","nd","rd","th"};

而不是char mon[12]{"January","February".........}，char da[4]{"st","nd","rd","th"}
