1.1 I/O

Only standard I/O is assumed for reading test data and writing results--no file opening.

overloaded operator>> and operator<<

#include <iostream>
using namespace std;

int main() {
       char c;
   while ( cin >> c ){
     cout << c;
   }
   cout << endl;
   return 0;
}

int eof ()
istream& getline (char* s, streamsize n [, char delim] )
Extracts a string of the specified length, unless the delimiter is encountered earlier. The character '\n' is implicitly assumed for a delimiter, when a delimiter is not explicitly provided.
int get ()
get a character

     cout << str << endl;

In the default setting, spaces are ignored when characters are read. The following switches can modify the behavior.
