Learn more about C++Builder at http://www.embarcadero.com/products/cbuilder. John Thomas of Embarcadero Technologies presents C++ and its renewed usage in the high-growth mobile application development market with emphasis on the iOS and Android platforms. The presentation covers the brief history of C/C++, its renewed importance in modern application development with current frameworks, new C++11 language features, and vendor language extensions.
