PSA′s experience allows us to perform numerous projects using the C++ language. C++ is a statically typed, free-form, multi-paradigm, compiled, general-purpose programming language. It is regarded as a middle-level language, as it comprises a combination of both high-level and low-level language features.
C  represents a general-purpose language for structured programming which design provides constructs that map efficiently to typical machine instructions, bringing in a lasting use for the language in applications that had formerly been coded in assembly language. C++ grew from enhancements of C, and later became the most popular programming languages ever created.
Some of its application domains include systems software, application software, device drivers, embedded software, high-performance server and client applications, and entertainment software such as video games. C++ is also used for hardware design, where design is initially described in C++, then analyzed, architecturally constrained, and scheduled to create a register transfer level hardware description language via high-level synthesis.
The advantages of C++ are obvious: better performance, portability, multiple inheritance, any type can be thrown as exception, ability to enforce const-correctness, offers pointers, support for macros, and allows default arguments on function parameters.
When not specified, C++ is unmanaged, compiled to the machine code. In case of unmanaged C++ the developer shall manage the memory allocation manually. Managed C++  is a language that compiles to bytecode run by the .NET Frameworks. Mainly it′s using the same syntax as C++ but is compiled in the same way as C# or VB.NET. Managed C++ was created to ease transition from classic C++ to the .NET Framework.
ANSI C  represents the family of successive standards for the C language. Developers are encouraged to conform to the standards while writing in C, as doing so aids portability between compilers.
Project Image The primary objective of the IP Intercom System Integration project was to integrate the client’s Intercom System into the Lenel OnGuard security system. The important aspect of the integration is in implemented possibility for the Intercom System to interface with OnGuard, including access control. The main aim was to develop software (Device Translator) that helps the series of customer’s Intercoms communicate with the OnGuard security system.
Project Image The main goal of the Cash Drawer Driver Development project was to convert existing 32-bit cash drawer WDM driver for 2 models of POS terminals into a 64-bit driver using Kernel-Mode Driver Framework (KMDF).
Project Image The main objective of the Solid State Drive (SSD) Self-Test Diagnostics Framework project performed for one of the world leading semiconductor companies was to develop of the diagnostics framework and a set of real-time performance-optimization routines to be used during the manufacture and quality verification of each newly produced enterprise SSD.
Project Image Professional Software Associates, Inc. has performed development of several subsystems of a Computer Aided Dispatching system for freight railroads which allows planning and controlling movements of the trains. This system allows dispatchers to easily track and control the status of trains, tracks, and field units being dispatched.
