What mechanism does C++ have for handling unsuccessful memory allocation in new-expressions?

try-catch exception handling
Automatic garbage collection
An error code returned by the new operator
A compiler warning during compilation

The correct answer is: try-catch exception handling

In C++, try-catch exception handling is used to handle unsuccessful memory allocation in new-expressions. This is because C++ does not have automatic garbage collection, which is an automatic process of freeing up memory allocated by the program. Additionally, the new operator does not return an error code when unsuccessful, as it can only return a pointer to the allocated memory. A compiler warning during compilation may be helpful, but it does not handle the issue at runtime like try-catch exception handling does.
