What do You Use C++ Exceptions For? [closed]

Answer 1

Although a lot of people treat exceptions in C++ really as 'something exceptional happened', I find them incredibly handy to do basic error-checking / validation as well, mostly at application-level (as in not in the core of the library)

Example, I'd rather write

try
{
  MethodA();
  MethodB();
  //.. a whole lot of other methods crucial to succeed for app initialization
}
catch( const SomeException& e )
{
  //show user the critical error contained in e
  return 1;
}

then writing

if( !MethodA() )
{
  //retrieve and show error
  return 1;
}
if( !MethodB() || !MethodC() )
{
  //retrieve and show error
  return 1;
}
//etc

This tends to lead to less code, also within the methods themselves.
