Re: bad_alloc

Hello everyone,


I am wondering except when there is no memory on heap, are there any other
situations when we will get bad_alloc exceptions? For example, invalid
input of the size (e.g. very huge number or zero or negative number) will
cause exception?

Of course.

new will fail whenever (free contiguous memory < requested allocation size)

This inequality can be satisfied just as easily by a ridiculous righthand
side as by a small lefthand side.

Note however that you shouldn't rely on this mechanism to detect invalid
input. You should not pass a user-supplied value to new.



thanks in advance,
George
