What are the implications of defining a function inside a class body in terms of its expansion?

  1. The function is always virtual.

  2. The function can only be called statically.

  3. The function is expanded at the location of each call.

  4. The function cannot take arguments.

The correct answer is: The function is expanded at the location of each call.

Defining a function inside a class body means that the function will be expanded at the location of each call, which means that a copy of the function's code will be added to the call site before the program is executed. This can be useful for functions that are only needed within the context of the class, but it can also cause unnecessary code bloat and decrease performance if the function is called frequently. Option A is incorrect because defining a function inside a class body does not make it always virtual. Virtual functions are declared with the keyword "virtual" and are used for dynamic polymorphism. Option B is incorrect because a function defined inside a class body can still be called statically. It just means that a copy of the function's code will be added to the call site, but it can still be called like any other function. Option D is incorrect because a function defined inside a class body can
