Programming Languages Essay -- essays research papers

Programming LanguagesA programming style is a designate of English-like instructions that includes a set of rules for putting the instructions together to create commands. A interpretive program changes the English-like commands into mathematical mark that the computer mountain understand. The most common type of translator is a compiler. The compiler is program that reads English-like commands in a file and than creates some other file containing computer readable numeric code or commands. I will be talking about some of the major functions and uses sixsome high-level programming languages. burnt umber was authentic by Sun MicroSystems and released in 1995. burnt umber is based on C and C++ and incorporates many features object-oriented languages. It is a compiled language, but its code output is see. This makes Java ideal for cross-development. The downside to its interpreted code is speed. Javas object-oriented is fundamental, and all code and data in a Java program e xist within the object-oriented class. Javas exception handiling with try, catch, and throw statements provide the solution for writing reliable code that responds to all possible error conditions. Another advantage of Java is a String class that does away with null-terminated, length byte and other types of strings. It is also multithreaded which a class can easily provide code that runs concurrently with other programing. Another advantage is the lack of a pointer-type data and memory trouble which tends to be a very bug-prone area. Memory is organized by Javas virtual machine garbage collector. Java provides a lively class library in beavery bug-prone area. Memory is organized by Javas virtual machine garbage collector. Java provides a exuberant class library in the forms of packages imported into modules. Since Java is interpreted topically on the users system, a security manager can completely control disk access, window creation, and memory management.C was developed by Den nis Ritchie at Bell Labortories in 1972. C was originally intentional as symbolic code that formalized programming prasctices used at the time. In 1978 C blossomed into what was to become the most popular programming language ever. C offers programmers three advantages The first is general pourpose programming which allows you to write games, problem software, utilities, mathematical models, wordprocessors, spredsheets,... ...equence. Cobol has a certain minimum amount of code that is requisite for all programs, this is usually called a shell program.Delphi is a Rapid masking progarm which now progrrammers can use tools which are more intuitive and visual. Delphi uses objective lens Pascal as its foundation language, which has been one of the fastest compilers in the business. also object-based extensions has been added to the language to support good programming practices and efficent code. Delphi is capeble of using OCX controls, which is a 32-bit OLE-based made-to-order c ontrol. Delphi also allows you to create OLE automation servers and clients. These automation objects give you the flexibility of creating programs that act tasks in the backround and put the results back to your application. Anoter advantage for Delphi is the ability to write multi-threaaded applications. In a multi-tasking enviorment thi is important, as your applications become more comple, it is necessary to execute your applications in seprate pieces, which are called threads.In conclusion, the following was an overview of six high level languages. some(prenominal) are similar, but there are very distinct features and advantages to each(prenominal) language
