    Description

    You have just moved from Waterloo to a big city. The people here speak an incomprehensible dialect of a foreign language. Fortunately, you have a dictionary to help you understand them.

    Input

    Input consists of up to 100,000 dictionary entries, followed by a blank line, followed by a message of up to 100,000 words. Each dictionary entry is a line containing an English word, followed by a space and a foreign language word. No foreign word appears more than once in the dictionary. The message is a sequence of words in the foreign language, one word on each line. Each word in the input is a sequence of at most 10 lowercase letters.

    Output

    Output is the message translated to English, one word per line. Foreign words not in the dictionary should be translated as "eh".

    Sample Input

    dog ogday
    cat atcay
    pig igpay
    froot ootfray
    loops oopslay

    atcay
    ittenkay
    oopslay

    Sample Output

    cat
    eh
    loops

    分析:
    给定一些单词以及每个单词对应的意思,这之间是一一对应的。然后询问某一个单词对应的意思是什么,如果有对应的意思的话,就把对应的意思输出来,否则输出“eh”。

    代码:

    #include <iostream>
    #include <string>
    #include <map>
    #include<stdio.h>
    using namespace std;
    map <string,string>mp;
    int main ()
    {
        char ch[30],str1[15],str2[15];
        while (gets(ch))
        {
            if (ch[0]==0)
                break;
            sscanf(ch,"%s%s",str1,str2);
            mp[str2]=str1;
        }
        while (gets(ch))
        {
            map<string,string>::iterator it;
            it=mp.find(ch);
            if (it!=mp.end())
                cout<<(*it).second<<endl;
            else
                printf("eh
    ");
        }
        return 0;
    }
