Why is it useful to define templates inside a namespace?

To force instantiation at runtime instead of compile time.

To avoid name conflicts and logically organize generic functions.

To allow implicit calls from any source file.

To restrict access only to internal template classes.

Why is it important that the what() methods in custom exception classes are declared virtual?

To enable overriding and correct use via base class pointers.

To allow sending messages to std::cerr.

To allow calling them directly from the main() function.

Because all methods in std::exception must be static.

Completely removing generic types from code.

Overriding only the display() method for a specific type.

Allows the compiler to choose between two generic classes.

Defining a completely different implementation for a concrete type.

In what situation is it more appropriate to use an interface instead of a regular abstract class?

When we have different classes that need to share the same behavior without inheriting state or implementation.

When we want to provide partial implementation and common attributes for multiple classes.

When we want to limit access to methods only within the inheritance hierarchy.

When all derived classes are part of a logical hierarchy and have the same internal structure.

What happens if you try to throw std::invalid_argument() without providing a message?

The std::exception constructor is automatically called.

The program runs, but displays "unknown exception".

An empty message is returned.

The compiler generates an error because there is no default constructor.

To allow a class to inherit from an interface.

To force the redefinition of inherited methods.

To prevent ambiguities caused by diamond inheritance.
