Designing Callbacks in C++ – Part 1: Function Pointers
In this article we will discuss what is a callback and what types of callbacks we can have in C++ and how to Design Callbacks as function pointers.
C++ Interview Questions
What is a Memory Leak in C++ ?
In this article we will discuss what is Memory Leak C++ and why its harmful for applications.
Differences between a pointer and reference
Differences Between Pointer and Reference in C++ are as follows,
Allocating and deallocating 2D arrays dynamically in C and C++
In this article we will see how to allocate and deallocate 2D arrays dynamically using new / delete and malloc / free combinations.
Designing Code for Fibonacci Sequence without Recursion
What’s a Fibonacci sequence: Fibonacci sequence is a kind of sequence in which every subsequent number is sum of the previous two numbers i.e. 0,1,1,2,3,5,8,13,21,34,55,89,144
Designing Code to Convert the base of a Number to any other base in Number System
In this article we will discuss how to design a Class that represents the Number in a Number System and also provides the facility to convert the Base associated with that Number i.e. conversion from any Base to any other base like, octal to hexa or hexa to decimal etc. [showads ad=inside_post] Create a class Number that …

Using STL to verify brackets or parentheses combination in an expression
In this we will see how to check if a given string take valid combination of open and close brackets i.e. (4+{8-[22+8]*}] contains valid order of open and close brackets. ({5+8]) contains invalid combination of open and close brackets. [showads ad=inside_post] Bracket combinations to be used, { , } [,] (,) Algo Used: Create a empty stack of characters Traverse …

How virtual functions works internally using vTable and vPointer?
In this article we will discuss that how virtual functions in C++ works internally using vTable and vPointer.
When to use virtual functions in C++?
When we want a Derived Class to override a member function of Base class, then we should make that member function in Base class virtual. So that if someone uses the Derived class object using Base class’s pointer or reference to call the overridden member function, then function of derived class should be called.
Object Oriented Approach to Display a sequence of numbers without any For-Loop or Recursion
Suppose we have to display a sequence of numbers like from 10 to 20 i.e.
