将字符串g fmnc wms bgblr rpylqjyrc gr zw fylb. rfyrq ufyr amknsrcpq ypc dmp. bmgle gr gl zw fylb gq glcddgagclr ylb rfyr'q ufw rfgq rcvr gq qm jmle. sqgle qrpgle.kyicrpylq() gq pcamkkclbcb. lmu ynnjw ml rfc spj.

位移加密，依次向后移动2位，y和z移动后成为a和b，则C++代码如下：

#include
using namespace std;
void main()
{
char str[] = "g fmnc wms bgblr rpylqjyrc gr zw fylb. rfyrq ufyr amknsrcpq ypc dmp. bmgle gr gl zw fylb gq glcddgagclr ylb rfyr'q ufw rfgq rcvr gq qm jmle. sqgle qrpgle.kyicrpylq() gq pcamkkclbcb. lmu ynnjw ml rfc spj.";
          

int i = 0;
 while(str[i])
 {
  if((str[i]-'0'!=-16)&&(str[i]-'0'!=-2))
  {
   if(str[i]-'0'!=73)
   {
    if(str[i]-'0'!=74)
    {
         str[i] = str[i]-'0' + 2 + '0';
    }
    else
     str[i] = 'b';
   }
   else
                 str[i] = 'a';
  }

  i ++;
 }
 cout<<str<<endl;

}

输出如下：
