Question 3)What is the output of this problem.
int i=12;
int &r =i;
r+r/4;
int *p = &r;
P+=r;
return i;
Answer :a)12 b)17 c) 30 d)24 E)15
// Answer will be 12.
r is a reference to i so both r and i will be 12 at first.
r+r/4 is meaningless as there is no assinment.
p is a pointer so increamenting p will not manipulate the
value stored at p(The value of r will not be changed if we
increase p if we want to increase the value of r then we
have to do (*p)+=r).
Qustion 4:
//It will output the reverse string.
Question 5:
Not clear with the question.
Question 6:
//Space is always reserved for base class variables in
derived class objects.So if sizeof(int)=4 and sizeof(char)=1
then answer will be
5 Bytes for Class A and 10 Bytes for Class B.
