0

{0..0}

Explanation / Answer

Answers:

1) True: Destructors are used to destroy the memory allocated for the object. User can define a destructor for a class using ~ followed by the class name. Compiler will provide a default destructor in case if no destructor is provided.

2) dot: Dot operator is used to access the members of a class. Compiler finds the method which the object accessing by passing the address as an unseen argument.

3) {0}: By specifying this the array can be initialised by 0 i.e

              int rent[20]={0} the entire array is initialized to 0

4) debug: Basically debugging and testing are same at a basic/initial level but at higher levels testing has much more to do than debugging. Debugging is done manually, test is done automated at higher levels.
