Re: [algogeeks] Question asked in Amazon Online Test
i think this algo will do...
reverse the given prefix expression
while(!nd of input)
{ if it is operand
push in a stack
if its an operator
{ op1=pop(stack);
op2=pop(stack);
push (op1 op2 operator) on to stack;
}
}

make a binary tree of given expression in O(n) then do postorder

Re: [algogeeks] Adobe interview question
So, i think there is no way to implement abstract class without using pure virtual functions since 1. if we make the constructor private then derived classes cannot be instantiatedthey too become abstract class. 2. if we make constructor protected, then derived class will be able to create (instantiate ) objects of base classwhich is ofcourse we dont want any other way would be highly appreciated On Wed, Jun 27, 2012 at 11:16 PM, rahul sharma rahul23111...@gmail.comwrote: @himanshu...i didnt read full question.got it now...

This is because, when delete bPtr; is called, the base class destructor
will be called as bPtr is of type baseClass.
And since baseClass destructor is not decalred as virtual, so the type
of the object that bPtr points to does not come into picture.
In other words, the base part of memory held by derivedClass2 object
will only be destructed here.
@Prem Krishna Chettri's question: In this case also only the
baseClass's destructor will be called and hence we will have two lines
output as
baseClass Des called
baseClass Des called
This is why it is always advisable to make the destructor as virtual.

Now why ..
It is no more than just a base parent concept here, so base pointer
capable if holding its derived object address get's derived object as new
derivedClass2() creates only derived object. However, by deleting that
pointer would results in destructing of this object which is the object of
the derived class type derivedClass2.
Well, I Guess what would be more interesting if you have a main
something like this :-
int main() {
baseClass *aPtr = new derivedClass1();
baseClass *bPtr = new derivedClass2();
delete aPtr;
delete bPtr;

Re: [algogeeks] Re: interview ques
@bharath: yeah i was also thinking that we could store a pointer to a data block in which multiple records can be stored.but i think for searching a record we have to 1st get to that block and then search the record in that block On Thu, Jul 28, 2011 at 5:31 PM, bharath bharath.sri...@gmail.com wrote: @Puneet, to store anything on a machine, you will need to have a pointer to it else there is no question of accessing it. I am guessing the question emphasized on reducing the size of the B+ tree. Also, with B+ trees, you have sequence pointers at the data record level. Therefore, if these data records are stored in a single chunk, bringing the chunk into memeory is good enough. An additional storage structure will not be required.

Re: [algogeeks] c++ doubt
thanku sir...sir 1 more thngcn u gv a link or some pdf for studying
virtual inheritance elaborating the vptr mechanism more clearly...
On Sun, Jul 10, 2011 at 11:56 PM, Sandeep Jain sandeep6...@gmail.comwrote:
The reason is... that when u write
a obj1=14;
it is same as writing a obj1 = a(14);
So first a temporary object is created using the constructor
a(int i)
And this temporary object is passed in the copy constructor. BUT since it
is temp object it must be referred by a const alias.

Re: [algogeeks] function overloading in inheritance
Thanku sir...:)
On Mon, Jul 4, 2011 at 1:59 PM, Sandeep Jain sandeep6...@gmail.com wrote:
This happens because the Derived class's member *hides* the base class's
member.
Irrespective of the number/type of parameters.
The solution to solve this problem is to either add an using declaration in
the derived class.
e.g. *using A::f;*
this will bring f(int) of class A within the scope of class B, and thus
allowing the overload to work
or you need to use the scope resolution operator to explicitly call class
A's hidden function.
e.g. *b.A::f(4);*
Hope this helps.

@ T3rminal That is because the term is resolved as 2[*arr] which is
