#include <string>
using namespace std;

int main()
{
    string str = "0123456789";

    cout << "The current capacity of the string is:" << str.size() << endl;
    str.resize( 20 );

    cout << "The new capacity of the string is:"
         << str.size() << endl;           

    cout << "The actual length of the string is: "
         << strlen( str.c_str() ) << endl;

    cout << "The string object after resizing "
         << "to 20 a 10 character string: "
         << str << endl;
