Quick Introduction to *a concept* in C

I've been writing C++ programs since past 5 years now (I didn't realize it has been that long until I typed this out) and have come across various concepts that beginners seem to struggle with.

To help my fellow programmers in the community, I started a series of articles called Quick Introduction to a concept in C++. These articles are generally 2 to 5 minute reads that cover a specific concept in C++ in simple words, contain examples and point to comprehensive resources as well.

I read and reply to comments often, and you can suggest any topics you'd like to be covered in this series.

Here is a list of all the articles currently in the series :
(I'll keep updating this list as and when I write new articles)

Quick Introduction to namespaces in C++
Quick Introduction to using in C++
Quick Introduction to typedef in C++

As always, thanks for giving this article a read and I'll see you in the next one
