描述

Mr. B, Mr. G and Mr. M are now in Warsaw, Poland, for the 2012’s ACM-ICPC World Finals Contest. They’ve decided to take a 5 hours training every day before the contest. Also, they plan to start training at 10:00 each day since the World Final Contest will do so. The scenery in Warsaw is so attractive that Mr. B would always like to take a walk outside for a while after breakfast. However, Mr. B have to go back before training starts, otherwise his teammates will be annoyed. Here is a problem: Mr. B does not have a watch. In order to know the exact time, he has bought a new watch in Warsaw, but all the numbers on that watch are represented in Roman Numerals. Mr. B cannot understand such kind of numbers. Can you translate for him?

See the sample input for further information.

思路：字符串的比较。

 

 #include <stdio.h>#include <string.h>int main(){int i,total = 1;char str[5];const char *s[] = {"I","II","III","IV","V","VI","VII","VIII","IX","X","XI","XII",};while (scanf("%s",str) != EOF){for (i=0; i<12; i++){if (strcmp(str,s[i]) == 0){printf("Case %d: %d\n",total,i+1);total++;break;}}}return 0;}
