Printing String Issues

[- Steve -]

I have a class that has a private member char *buf which is basically a
pointer to a string.

I have a member function called print(); which consists of

void String::print()
{
cout << name;
cout << ":\t\"";
cout << buf;
cout << "\"\t" << length << " characters"<< endl;
}

But the cout << buf prints out maybe half of the string. When gives a weird
symbol (usually a Spades symbol), and then continues on it's merry way. But
if I use the debugger (Visual Studio 2002) it prints correctly.

Presumably a debug helper function.

It's not zero terminated.

Use

cout << std::string( buf, buf+length )

or something like that -- check the std::string constructors.

Well that means you have a bug in your program. Unfortunately is not
possible to tell what that is from the above code. Bugs which only show up
in release versions are the bane of many programmers lives. Like bugs which
only show up on customers machines, or bugs which only show when there is a
full moon, there all still bugs.
