Application Developing

Developed different means of working with files. Since the commands of programs written in that language, active use of ordinary English vocabulary and syntax, COBOL is regarded as one of the most common programming languages. It is currently used for solutions to economic, informational and other problems. Assembler language is the clearest representative _nizkogo level, a set of concepts which is based on the hardware implementation. This automation tool for programming directly in the codes of the processor. Machine instructions are described in the form of mnemonic operations, to achieve a sufficiently high modifiability of code.

Because the instruction set is different on different processors, then on compatibility, however. Using assembler useful in cases where it is necessary to directly interact with the equipment, or to obtain more effective for some part of the program for by a higher control over code generation. C and C + + language based in C – systems programmer requirements: full and effective access to all computer resources, means of high-level programming, portability programs between different platforms and operating systems. C + +, while maintaining compatibility with C, introduces object-oriented programming, expressing the idea of a class (object) as a user-defined type. Thanks to these qualities, C / C + + took the position of a universal language for any task. But its use may be ineffective where it's needed to get ready to use the result as soon as possible, or where it becomes unprofitable itself a procedural approach. Delphi – is not a continuer of Borland Pascal / Borland C, its niche – that is, rapid application development (Rapid Application Developing, RAD).
