In c++ the dot is an operator, what does it do

when you pass the if or of stream to a variable as a function how do you pass it

what do you put in front of a logical expression to reverse its value

4 choices: only one of them is a reserve word

++ operator  : preincrement and postincrement:
Int a = 0
Int b = 0



B = ++A; means 1 is added to A then B becomes A: Preoperator
B = A++; means B becomes A then 1 is added to A: Postoperator

what is a valid char?

7 fill in the blanks, rest are multiple choice, total of 32 questions.

question 13 may want to use the compiler

For loop printing out the values of an array

DO you know the length of a string from looking at it?

calling conventions: two perspectives of a function: formal or actual: perspective
of the caller or the perspective of the called
static_cast{int}

two dimensional array
index operators

Member access specifier for a class
Inheritance: Base class and derived class?

which of the following class definitions makes the public members of the class A
class become the public members of the class B class

Question 26: Series of expressions: which one will evaluate to true? pick the one
that is ALWAYS true

Test does end with true or false questions actually

enum: understand the syntax

what is Macgyver's first name?

TO develop a program to solve a problem, you start by analyzing the problem.
