15.15.3.Use cin to read string
#include <iostream>
using std::cout;
using std::endl;
using std::cin;
using std::boolalpha;

#include <string>
using std::string;

void displayconst string & );

int main()
{
   string string1;
 
   cout << "Statistics before input:\n" << boolalpha;
   displaystring1 );

   cout << "\n\nEnter a string: ";
   cin >> string1; // delimited by whitespace
   cout << "The string entered was: " << string1;

   cout << "\nStatistics after input:\n";
   displaystring1 );


   return 0;
}

void displayconst string &stringRef )
{
   cout << "capacity: " << stringRef.capacity() << "\nmax size: "  
      << stringRef.max_size() << "\nsize: " << stringRef.size()
      << "\nlength: " << stringRef.length() 
      << "\nempty: " << stringRef.empty();
}
Statistics before input:
capacity: 0
max size: 1073741820
size: 0
length: 0
empty: true

Enter a string: a string
The string entered was: a
Statistics after input:
capacity: 1
max size: 1073741820
size: 1
length: 1
empty: false"
