Re: C++ Primer ex 6.20

at chapter 6, so i have not encountered stuf like Functions):

/* C++ Primer - 4/e
*
* exercise 6.20
* STATEMENT
* write a programme to rad a sequence of strings from standard
input until either the same word occurs twice in succession or all the
words have been read. use the while loop to read a word at a time. use
the break statement to terminate the loop if awords occurs twice in
succession & print that word or else print the message that no word was
repeated.
*
*/

#include <iostream>
#include <string>

int main()
{
 std::string cstr, pstr;
 bool same_str = false;

   {
     if(cstr == pstr)
       same_str = true;
     pstr = cstr;
   }

if(same_str)
     std::cout << "\n'" << cstr << "' was repeated\n";
 else
     std::cout << "\nno word was repeated\n";

 return 0;
}
