Question
Q2: The code fragment:Increment::Increment( int c, int i )
: increment ( i )
{
count = c;
}
does not cause any compilation errors. This tells you that:

b. count must be a const variable.
c. increment must be a non-const variable.
d. increment must be a const variable.

Q3[C++11]: Which of the following statements about inheriting base class constructors is false?
