STL sort throw exception?

[George2]

Hello everyone,


In Bjarne's book, it is mentioned that sort of STL may throw exception, like sorting elements in a vector.

In what situation will sort throw exception? I can not find a case.


thanks in advance,
George

Where does he mention it??

The sort should not throw although exceptions can be thrown by predicates. You should always presume exceptions whenever you use STL algorithms.

George, while we have been helping you, your behavior feels very similar to that of a help vampire. Furthermore, you seem to be posting to multiple boards at once. Also see http://cboard.cprogramming.com/showthread.php?t=97544. And http://www.eggheadcafe.com/software/...exception.aspx.

Starting multiple threads on the same question wastes people's time, as they are completely oblivious to other trains of thought. Perhaps you should review how to ask smart questions, an excellent article on the mentality and etiquette on technical forums.

EDIT: This is not the only thread George has been spamming multiple boards. Check his other questions. They have been multi-spammed everywhere, including Usenet.

Hi weaknessforcats,


You can refer to his book, appendix E, Standard-Library Exception Safety, in the 1st sample in E.1 (Introduction).

He doesn't say that the sort throws an exception.

What is does say is that the code that compares two objects can throw an exception.

There's a difference.

It all comes down to using try/catch blocks liberally when writing C++. To not do that just invites a crash.
