Learn State Design Pattern by Designing a Simple Music System
Many times we need to develop systems / objects that provides services to outside world. But the response of each service is not always same, it depends upon its current internal state.
Be careful with hidden cost of std::vector for user defined objects
While creating and using std::vector with user defined classes we needs some special care otherwise it can hamper the performance of our application.
Using std::find & std::find_if with User Defined Classes
std::find and std::find_if algorithms are used to find first element in the given range.
Remove Duplicate Elements from a Sorted Singly Linked List
Lets remove all duplicate elements from a sorted singly linked list.
Reverse a Singly Linked List in a Single Iteration
Suppose we have a linked list and we want to reverse it in Single iteration and O(n) complexity.
Create a Singly Linked List from an array
Suppose we have an int array and we want to create it into a singly linked list from it.
C++11 Smart Pointer – Part 5: shared_ptr, Binary trees and the problem of Cyclic References
Main advantage of shared_ptr is that it automatically releases the associated memory when not used any more.
C++11 Smart Pointer – Part 4: Create shared_ptr objects carefully
We should create shared_ptr objects carefully. Checkout below two cases,
C++11 Smart Pointer – Part 3: shared_ptr vs Pointer
In this article we will compare C++11 Smart Pointer Implementation shared_ptr and a normal pointer.
C++11 Smart Pointer – Part 2: shared_ptr and Custom Deletor
In this article we will discuss how to use custom deleter with std::shared_ptr.
