Exception on bad array length
Type of the exceptions thrown by array new-expressions in any of these cases:
- If the array size is less than zero.
- If the array size is greater than an implementation-defined limit.
- If the number of elements in the initializer list exceeds the number of elements to initialize.
This class is derived from bad_alloc (which is itself derived from exception). See the exception class for the member definitions of standard exceptions.
Its member what returns a null-terminated character sequence identifying the exception.

Possible output:
bad_array_new_length caught: bad array new length |
Exception safety
No-throw guarantee: no members throw exceptions.
