Answer / achal ubbott
* Stack is a kind of data structure where Last In FirstOut
work. Local variables are needed for a short span of time
for immediate processing. So push and pop from stack is
used for them. Now memory is allocated to them in static
time only.
* new() operator allocates memory dynamically. Since
objects are needed for more time, space is taken from heap.

class Alpha { public: char data[10000]; Alpha(); ~Alpha(); }; class Beta { public: Beta() { n = 0; } void FillData(Alpha a); private: int n; }; How do you make the above sample code more efficient? a) If possible, make the constructor for Beta private to reduce the overhead of public constructors. b) Change the return type in FillData to int to negate the implicit return conversion from "int" to "void". c) Make the destructor for Alpha virtual. d) Make the constructor for Alpha virtual. e) Pass a const reference to Alpha in FillData
