C++ Exceptions in Console App?

May be a dumb question, but I would like to use C++ exceptions in a console app (created with the new Win32 Console Application project wizard). I tried many variations on the theme shown below with no joy:

try {
  // do something that may throw an exception
}
catch( exception e ) {
  printf( "Exception: %s\n", e.what );
}

The compiler complains that identifier 'exception' not found.
I tried various things in place of 'exception' (e.g., 'IOException', 'bad_alloc') with no luck.

I tried different exception-related options in the project configuration, also with no luck.
I was able to make it compile using 

catch(...) {

but that gives me no info about the exception.

Questions:
Are exceptions even allowed in non-.NET apps?
Am I missing some include file?
Some other (dumb) thing I did or didn't do?

Yes, they are.

Am I missing some include file?

It looks like you're missing the necessary #include <exception> and/or the namespace scoping with std::.

Some other (dumb) thing I did or didn't do?

The better way to catch exceptions is by const reference BTW:

#include <exception>

int main() {
    try {
      // do something that may throw an exception
    }
    catch(const std::exception& e ) {
        printf( "Exception: %s\n", e.what );
    }
}
