What will be the output of the following C++ code?

#include <iostream>
#include <ios>
#include <istream>
#include <limits>
using namespace std;
template <typename CharT>
void ignore_line ( basic_istream<CharT>& in )
{
    in.ignore ( numeric_limits<streamsize> :: max(), in.widen ( '\n' ) );
}
int main()
{
    cout << "First input: ";
    cin.get();
    cout << "Clearing cin.\n";
    cin.clear();
    ignore_line ( cin );
    cout << "All done.\n";
}
