// The following example was provided by Jeff Cutsinger

// Spring 2004

// The goal of the example is to get dynamically allocate
// just enough memory for a c-style string for the continence
// in the input buffer.

#include <iostream>
#include <strstream>

using std::ostrstream;
using std::ends;
using std::cin;
using std::cout;
using std::endl;

void main()
{
	ostrstream Buffer;
	cin.get(*Buffer.rdbuf());
	Buffer << ends;	//adds a null terminator to the end of the internal string
	Buffer.freeze(); // ensures that the string will not be dealocated when Buffer goes out of scope

	char* pString = Buffer.str();

	cout << pString << endl;

	delete pString;
