map应用不熟悉，还有就是， 我发觉map运行总是很久

 

#include <iostream>#include <string>#include <cstring>#include <fstream>#include <map>using namespace std; char s1[11], s2[11]; int main(){ifstream in("OpenJudgeText.txt"); int i, j, len=0;;char c, s[22]; map<string, string> m; string str1, str2; do{gets(s);if(strcmp(s, "\0")==0)break; for(i=0; s[i]!=' '; i++)s1[i] = s[i];s1[i++] = '\0'; for(j=0; s[i]!='\0'; i++, j++)s2[j] = s[i];s2[j] = '\0';str1 = s1; str2 = s2; m[str2] = str1; }while(true); while(true){memset(s2, 0, sizeof s2);gets(s2);if(strcmp(s2, "\0")==0)break; str2 = s2;if(m.count(str2))cout<<m[str2]<<endl; else cout<<"eh"<<endl; }//cin>>i; return 0; }
