How to print an entire istream to standard out and string

Question

How do you print an istream variable to standard out. [EDIT] I am trying to debug a scenario wherein I need to ouput an istream to a log file

Answer 1

This will print the whole stream, 1 character at a time:

char c;
c = my_istream.get();
while (my_istream)
{
    std::cout << c;
    c = my_istream.get();
}

This will print the whole thing, but discard whitespace:

std::string output;
while(my_istream >> output)
    std::cout << output;
