Delphi is the most powerful Object Pascal IDE and component library for cross-platform Native App Development with flexible Cloud services and broad IoT connectivity. It provides powerful VCL controls for Windows 10 and enables FMX development for Windows, Mac and Mobile. Delphi is your choice for ultrafast Enterprise Strong Development™. Look for increased memory for large projects, extended multi-monitor support, improved Object Inspector and much more. Delphi is 5x faster for development and deployment across multiple desktop, mobile, cloud and database platforms including 32-bit and 64-bit Windows 10.

Programming includes both the specifics of the language you’re using, like Visual Basic, .NET, Java and others, but also the best practices in user experience and interfaces and the management of projects, version control and development. Other programming topics are related to web and cloud development and system and hardware programming.

Programming

Programming theory deals with the design, implementation, analysis, characterization, and classification of programming languages and their individual features, along with introductory programming concepts like program structure, variable declaration and conditional and looping constructs. Sub-disciplines include the formal semantics of programming languages, type theory, program analysis and transformation, comparative programming language analysis, metaprogramming, domain-specific languages, compiler construction and run-time systems.
