C++ Programming Online Test4 preparation for interview

Thank you very much for taking test

Test your caliber

1. Each pass through a loop is called a/an ____?
enumeration	iteration
culmination	pass through

2. Which looping process checks the test condition at the end of the loop?
for	while
do-while	no looping process checks the test condition at the end

3. A continue statement causes execution to skip to _____?
the return 0; statement	the first statement after the loop
the statement following the continue statement	the next iteration of the loop

4. In a group of nested loops, which loop is executed the most number of times?
the outermost loop	the innermost loop
all loops are executed the same number of times	cannot be determined without knowing the size of the loops

5. The statement i++; is equivalent to ____ ?
i = i + i;	i = i + 1;
i = i - 1;	i --;

6. Which looping process is best used when the number of iterations is known?
for	while
do-while	all looping processes require that the iterations be known

7. What's wrong? for (int k = 2, k <=12, k++)
the increment should always be ++k	the variable must always be the letter i when using a for loop
there should be a semicolon at the end of the statement	the commas should be semicolons

8. What's wrong? while( (i < 10) && (i > 24))
the logical operator && cannot be used in a test condition	the while loop is an exit-condition loop
the test condition is always false	the test condition is always true

9. If there is more than one statement in the block of a for loop, which of the following must be placed at the beginning and the ending of the loop block?
parentheses ( )	braces { }
brackets [ ]	arrows < >

10. What's wrong? (x = 4 && y = 5) ? (a = 5) ; (b = 6);
the question mark should be an equal sign	the first semicolon should be a colon
there are too many variables in the statement	the conditional operator is only used with astringes

11. Which of the following operators below allow to define the member functions of a class outside the class?
::	?
:?	%

12. Every class has at least one constructor function, even when none is declared.
True	False
Both of the Above	none

13. How do we define a constructor?
X~() {}	X() {}~
simple Program	~X() {}

14. Can constructors be overloaded?
No	Yes
Both of the Above	None

15. Which of the following below can perform conversions between pointers to related classes?
cast_static	dynamic_cast
static_cast	cast_dynamic

16. An abstract class can be instantiated.
True	False
Both of the Above	None

17. The default access level assigned to members of a class is ___________.
Private	Public
Protected	Needs to be assigned

18. Which classes allow primitive types to be accessed as objects?
Storage	Virtual
Friend	Wrapper

19. Which of the following library function below by default aborts the program?
Terminate()	end()
Abort()	exit()

20. What defines a general set of operations that will be applied to various types of data?
Template class	Function template
Class template	none
