In C++ what are the benefits of using exceptions and try / catch instead of just returning an error code?

Question

I\'ve programmed C and C++ for a long time and so far I\'ve never used exceptions and try / catch. What are the benefits of using that instead of just having functions retur

Answer 1

The advantage of exceptions are two fold:

• They can't be ignored. You must deal with them at some level, or they will terminate your program. With error code, you must explicitly check for them, or they are lost.

• They can be ignored. If an error can't be dealt with at one level, it will automatically bubble up to the next level, where it can be. Error codes must be explicitly passed up until they reach the level where it can be dealt with.
