From the preceding discussion of using exceptions, you might gather (and gather correctly) that exception handling should be designed into a program rather than tacked on. Doing this has some disadvantages, though. For example, using exceptions adds to the size and subtracts from the speed of a program. Exception specifications don’t work well with templates because template functions might throw different kinds of exceptions, depending on the particular specialization used. Exceptions and dynamic memory allocation don’t always work that well together.

Let’s look a little further at dynamic memory allocation and exceptions. First, consider the following function:

void test1(int n){    string mesg("I'm trapped in an endless ...
