注意%输出！！！

#include<stdio.h>#include<string>char str[100];int main(){//freopen("a.txt","r",stdin);while(gets(str)){int len=strlen(str);if(len==1 && str[0]=='#')break; int i;for(i=0;i<len;i++){if(str[i]==' '){printf("%%20");//注意：要想输出一个%就要写两个，输出两个就写4个continue;}if(str[i]=='!'){printf("%%21");continue;}if(str[i]=='$'){printf("%%24");continue;}if(str[i]=='%'){printf("%%25");continue;}if(str[i]=='('){printf("%%28");continue;}if(str[i]==')'){printf("%%29");continue;}if(str[i]=='*'){printf("%%2a");continue;}printf("%c",str[i]);}printf("/n");}return 0;}
