Answer / Rajkumar Sharma
The declarations 'list x;' and 'list x();' both create a new std::list object named 'x', but they differ in how the object is initialized.n
1. list x;: This declaration creates an empty list without performing any initializations.
2. list x();: This declaration creates an empty list using the default constructor, which means that it invokes all the implicitly generated constructors for the specified type and sets up the necessary resources (e.g., memory allocations).
