Handling a constructor that fails requires the use of exceptions. When a constructor encounters an error during object initialization, it should throw an exception using the throw keyword. This allows the program to transfer control to an appropriate exception handler.
Utilize the try-catch block to catch the exception and handle the failure gracefully. Inside the catch block, implement error-handling mechanisms, such as displaying an error message, logging, or taking corrective actions. Properly handling constructor failures ensures robustness and maintains the integrity of the program, preventing unexpected crashes or undefined behavior.
