C++ is a very popular language and after 30 years, it’s still widely considered a best choice for many types of projects, including large scale systems and applications coding.
If you consider the layers of technology in a computer system as a stack, C++ is used to write code at all levels except firmware with its most common usage at the application level. Today, vast numbers of medium to large scale applications are written in C++. The list is huge and includes Microsoft Office, Adobe Photoshop, Illustrator, InDesign, Firefox, Google Chrome, provisioning service and billing systems for major phone and networks, even major web sites like Amazon, Facebook, and Google are either written in or have significant backend resources written in C++.

Ratified in August, 2011, C++11 is the first real extension of the C++ Standard. It provides a number of new features, including a range based for loop, type inference, lambda functions, and unambiguous null pointer constant,
and most of TR1.

Technical Report 1 or TR1 is mostly a set of library extensions, including regular expressions, smart pointers, hash tables, and random number generators.
