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 display( const string & );



int main()

{

   string string1;

 

   cout << "Statistics before input:\n" << boolalpha;

   display( string1 );



   cout << "\n\nEnter a string: ";

   cin >> string1; // delimited by whitespace

   cout << "The string entered was: " << string1;



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

   display( string1 );





   return 0;

}



void display( const 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"
