Shell Sort Algorithm sorts elements in array at a specific interval. At first, it sorts the elements that are away from each other and successively reduces the interval between them. Shell Sort is named after Donald Lewis Shell who initially wrote it in a research paper called A High-Speed Sorting Procedure.
Data security is more important than ever in this day and age. To help you improve your data security, here are some practical steps from Lock Boss to implement today.
A pointer can be declared to point to another pointer which points to a variable. Here, the first pointer contains the address of the second pointer. The second pointer points to an actual memory location where the data is stored, i.e. a variable. That's the reason why we also call such pointers as double pointers.

The Standard Template Library (STL) is one of the most essential features of C++. It has very much grown in recent years. Basically, the Standard Template Library provides templatized, general-purpose classes as well as methods. These classes and functions/methods implement several popular and most commonly used algorithms as well as data structures.
C++17 is the next level evolution in modern C++ programming. It was officially standardized in December 2017, giving the developers a wealth of new features to write better codes. Adopting C++17 is a much easier step as adopting C++11. C++17 contains a huge number of library features and valuable language that can support and change the way we do programming in C++.
