Hello everyone , wecome to our NOT So Common C++ series. In the last post for NOT SO COMMON C++ we discussed about some shortcuts , initializations of pointers, structures ..etc. So today lets cover some tricky portions of C++ that are a bit confusing for the beginners. I hope you people have basic knowledge of class in C++.  Access Specifiers : public , private , protected. Lets see an example to get an overview of access specifiers- #include<iostream> using namespace std; class Example { private :     int priV ;                              // PRIVATE VARIABLE or PRIVATE MEMBER public :      Example()                           //Constructor      {             priV =  10;                  // initializing "priV"             proV =  4;                   // initializing "proV"     void pubFunction()            // PUBLIC FUNCTION     {         cout << "public Function executed and priV = " << priV;   //

LiFi - Light Fedility   Ever wondered what's worse than No Internet ?................. slow internet...right. In the last decade we have seen different ways in which we connect to internet. But ever thought of connecting to the internet at a wooping speed of 10Gbps in your house, neighborhood or at your office ?... it was only made possible by the Li-Fi technology which promises to bring 10Gbps connection speed to you. Li-Fi is still very much in its developing stage but it is already making alot of noise in the tech market. According to many experts the Li-Fi industry will touch $113bn by 2022 and may surpass our dear friend "The Wi-Fi". According to the reports Li-Fi is 100 times faster than Wi-Fi. In 2014 Sisoft(mexican company) was able to transfer data at a speed of 10Gbps using light lamps i.e using lightning spectrum.  How it Works?   In Li-Fi the data is transmitted by modulating the intensity of light coming out of the LED buld(when curre
