It is convenient to deal with this problem by string string.

#include <iostream>
#include <string>
using namespace Std;
String cipher (string &s); Referred to as a parameter, this function returns the string of a string class
int main ()
{
String s1, S2, S3,S4;
while (1)
{
Getline (CIN, S1);
if (S1 = = "Endofinput")
Break
Getline (CIN, S2);
Getline (CIN, S3);
S4 = cipher (S2);
cout <<s4<< Endl;
}
return 0;
}
String cipher (String &s)
{
Char *p = new Char[s.size () + 1];//set dynamic character array
P[s.size ()] = 0; Sets the last element of the array to 0, which is the null character, the end flag
int i;
for (i = 0; i < s.size (); i++)
{
if (S[i] <= ' E ' &&s[i] >= ' A ')
P[i] = s[i] + 21;
else if (' E ' < s[i] && s[i] <= ' Z ')
P[i] = s[i]-5;
Else
P[i] = s[i];
}
String S1 (p); Integer assignment
Delete[]p;
return s1;
}
