#include<iostream>#include<cstdio>#include<map>#include<cstring>#include<string>#include<algorithm>using namespace std;int main(){map<string,string> str;map<string,string> ::iterator pos;int i,j,n,t,r,k;char s1[30],s2[30],s3[3005];while (scanf("%s",s1)&&strcmp(s1,"START")!=0);while (scanf("%s",s1)&&strcmp(s1,"END")!=0){scanf("%s",s2);str[s2]=s1;}while (scanf("%s",s1)){if (strcmp(s1,"START")==0)break; }getchar();                                   //******while (gets(s3)){if (strcmp(s3,"END")==0)return 0;r=0;for (i=0;i<strlen(s3);i++){if (s3[i]>='a'&&s3[i]<='z'){s1[r++]=s3[i];}else{s1[r]='\0';r=0;if (str.find(s1)!=str.end())cout<<str[s1];elsecout<<s1;printf("%c",s3[i]);}}printf("\n");}return 0;}

刚开始没有加getchar();第二个START后面会有个空行，一直不明白为什么。后来问了学长才知道原来回车只是作为%s结束的标志，后面的gets(str3);会把回车吃掉。哈哈……还真是一个细小的问题，虽然细小，还是值得注意的
