哪位大哥帮忙看下小弟代码,为啥总是wa,#include <iostream> #include <string> using namespace std; char fir[75]; int key; //转换为相应字符的位置 int value(int val,int num) { int i=(val+num)%28; if(i>0&&i<27) i=i+96; else if(i==0) i=95; else i=46; return i; } //转换为响应的字符 void change(string str) { int len=str.length(); int now;//确定现在数据是在哪个位置 int v; for(int i=0;i<len;i++) { if(str[i]>='a'&& str[i]<='z') { now=(key*i)%len; int a=int(str[i]-'a'+1); v=value(a,i); fir[now]=char(v);//将字符付值到相应的位置 } else if(str[i]=='_') { now=(key*i)%len; v=value(0,i); fir[now]=char(v); } else { now=(key*i)%len; v=value(27,i); fir[now]=char(v); } } //输出数据 cout<<fir<<endl; } int main() { string strend; cin>>key; while(key!=0) { cin>>strend;change(strend); //cout<<endl; cin>>key; } return 0; } Followed by: Post your reply here: |
