You dont need a header for exception handling? You can include <exception> that includes a base class specifically designed to declare objects to be thrown as exceptions

Just the standard iostream.

I edited your topic title, because it was not very descriptive to your question.
Next time use more descriptive topic titles.

I'm guessing the OP is using some 20+-year-old compiler and can't understand why exception handling isn't working. Just a guess though.

if you want to catch an exception as a string, then you need to include the exception header

eg

#include <exception>

try
{
    if (there was a problem)
		throw std::exception("Some error");
}
catch (std::exception e)
{
   output e.what();
}

You don't need any header files but to throw/catch exceptions that are compatible with the standard libraries you can include these:

#include <exception>
#include <stdexcept>
