Why is it recommended to avoid throwing exceptions directly inside a class constructor?

Throwing exceptions directly in a C++ constructor can lead to several issues:

• If an exception is thrown, the object is considered not created, and the destructor is not called, which can lead to resource leaks if resources were allocated before the exception.
• Resource management becomes more complex, especially if memory allocation or file opening occurs in the constructor.

It is recommended to use the RAII (Resource Acquisition Is Initialization) idiom, where resources are managed by wrappers that guarantee release even in the event of exceptions. If an error might occur in the constructor, it is better to use factory methods or initialize outside the constructor.
