想复杂了。。。

    #include <stdio.h>    #include <string.h>    #define M 80    int main()    {        char a[M];        int i;        while(gets(a))        {            if(a[0] == '#') break;            for(i=0;((a[i]!='\0')&&(a[i] != '\n')); i++)            {                if(a[i]==' ') printf("%%20");                else                    if(a[i]=='!') printf("%%21");                    else                        if(a[i]=='$') printf("%%24");                        else                            if(a[i]=='%') printf("%%25");                            else                                if(a[i]=='(') printf("%%28");                                else                                    if(a[i]==')') printf("%%29");                                    else                                        if(a[i]=='*') printf("%%2a");                                        else printf("%c",a[i]);            }            printf("\n");        }        return 0;    }

一开始想的是这样的，但是一直出不来结果，不知道是哪里错了，求大神指点。。。
