Hello! This is C++.
Thank you so much for reading this and have a good one!
1. The destructors in C++ has to be classed for each and every object that has been created in order to destroy them from the memory
T or F
2. When you use an object, the ____ operator, and a non-static function of the object’s class, you actually pass the specific object’s address to the function as an unseen argument.
scope resolution
conditional
dot
address
3.
A convenient way to set all array elements to zero is to declare as follows: int rent[20] = ____;.
0
{0..0}
{0}
{}
5. You ____ a program to detect any possible errors
test
debug
interpret
run
scope resolution
conditional
dot
address
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.
