题目：从键盘输入月份的英文速写，程序显示数字月份。例如输入“May“, 则程序显示“May是5月份“。

#include <stdio.h>
#include<string.h>
int main()
{
  char* month_name[]= { "Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct", "Nov","Dec" };//将多个字符串放在字符数组里面
  char month[10];
  int i;
  gets(month);
  for (i = 0; i <12; i++)
  {
    if (strcmp(month, month_name[i]) == 0)//使用字符串比较函数，前者长返回1，相等返回0，后者长返回-1
    {
      printf("%s是%d月份", month, i+1);
      break;
    }
  }
  if (i >= 12)
  {
    printf("输入有误，请重新输入");
  }
}
