Programming Languages
A programming language is a set of English-like instructions that includes a set of rules for putting the instructions together to create commands. A translator changes the English-like commands into numeric code that the computer can 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 another file containing computer readable numeric code or commands. I will be talking about some of the major functions and uses six high-level programming languages.
Java was developed by Sun MicroSystems and released in 1995. Java is based on C and C++ and incorporates many features object-oriented languages. It is a compiled language, but it’s code output is interpreted. This makes Java ideal for cross-development. The downside to its interpreted code is speed. Java’s object-oriented is fundamental, and all code and data in a Java program exist within the object-oriented class. Java’s 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 management which tends to be a very bug-prone area. Memory is organized by Java’s virtual machine garbage collector. Java provides a rich class library in beavery bug-prone area. Memory is organized by Java’s virtual machine garbage collector. Java provides a rich class library in the forms of packages imported into modules. Since Java is interpreted locally on the user’s system, a security manager can completely control disk access, window creation, and memory management.
C was developed by Dennis Ritchie at Bell Labortories in 1972. C was originally designed 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, business software, utilities, mathematical models, wordprocessors, spredsheets,...

...equence. Cobol has a certain minimum amount of code that is required for all programs, this is usually called a shell program.
Delphi is a Rapid Application progarm which now progrrammers can use tools which are more intuitive and visual. Delphi uses Object 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 custom control. Delphi also allows you to create OLE automation servers and clients. These automation objects give you the flexibility of creating programs that perform 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. Many are similar, but there are very distinct features and advantages to each language
Lest a whole new generation of programmers grow up in ignorance of this glorious past, I feel duty-bound to describe, as best I can through the generation gap, how a Real Programmer wrote code. I'll call him Mel, because that was his name.
This computer programming language is used by many businesses' computers. COBOL handles numbers and text so that businesses can produce reports and keep track of all sorts of data. It has no idea what a date is.
This paper discusses about the historical event that takes place within the operating system and their recent development and progression. Therefore it is essential to have a clear comprehension on the operating system that is still accessible to recognize its fundamental strengths and weaknesses. Hence, it is imperative to evaluate the operating system we are reviewing to distinguish between them. Meanwhile, this paper also inspects on the difference between the open source and proprietary operating system. The discussion is mainly about the feature and application used in different operating system.
At first glance these two languages appear to be poles apart. Bash shell script with its roots in Unix terminal scripting versus a modern object oriented scripting language'. So, are these two languages really so different and what might they have in common? This documents aims to answer these questions.
What a feeling! Learning a new language gives individuals a new way of thinking and feeling. Learning a new kind of language involves having total commitment and total involvement from students and teachers. In the article, Beyond English Development: Bilingual Approaches to Teaching Immigrant Students and English Language Learners indicates there are various standard definitions that describe language (Billings, Martin-Beltran, and Hernandez, 2010). Language is used to communicate with others and is essentially human, but not limited to only human beings. As individuals learn English as their Second Language, they learn that language is acquired by all kinds of people in the same way.
With all the listed disadvantages there are work arounds that can allow them to become advantages or possibly be minimized or avoided as well. With any programming language advantages and disadvantages will be
The Ada language is the result of the most extensive and most expensive language design effort ever undertaken. The United States Department of Defense (DoD) was concerned in the 1970¡¦s by the number of different programming languages being used for its projects, some of which were proprietary and/or obsolete. Up until 1974, half of the applications at the DoD were embedded systems. An embedded system is one where the computer hardware is embedded in the device it controls. More than 450 programming languages were used to implement different DoD projects, and none of them were standardized. As a result of this, software was rarely reused. For these reasons, the Army, Navy, and Air Force proposed to develop a high-level language for embedded systems (The Ada Programming Language). In 1975 the Higher Order Language Working Group (HOLWG) was formed with the intent of reducing this number by finding or creating a programming language generally suitable for the department's requirements.
The programming language C++ can be used in many ways. It has exploded into the gaming community allowing PC game programmers to have access to a stabile, yet powerful, programming language, utilizing as little code as possible. It has also been used in other commercial software, such as word processors, audio players, screen savers, and other computer desktop tools.
The COBOL programming language is typically used in large scale databases in banks and insurance companies. Today, COBOL is rarely used to write new software applications. It has been replaced by the C/C++ programming language, but up until the 80’s all business software was written using COBOL. This includes but is not exclusively accounting, payroll, and large bank applications. COBOL is still used today due to the high cost of upgrading software, and recent studies show that as many as twelve million COBOL applications are still used today.
Computer programming can as well be defined as a process that leads from an original formulation of a computer problem to execute problems. Computer programming is also referred to as programming. It encompasses other activities such as understanding, analysis and generally solving problems that result in algorithm, verifying the algorithm requirements and coding algorithm in a target program language. The program also involves the implementation of the build system and managing derived artifacts like computer programs machine codes. Most often, the algorithm is represented in human-parseable languages such as Java, Python, Smalltalk among others.
The field of Computer Science is based primarily on computer programing. Programming is the writing of computer programs using letters and numbers to make "code". The average computer programer will write at least a million lines of code in his or her lifetime. But even more important than writting code, a good programer must be able to solve problems and think logicaly.
Choosing a career is very important in a person’s life. Over the past two decades, many professions have change significantly with the influx of technological developments. One needs to think about the things that interest them and what kind of lifestyle they want to have. Some things a person should think about are what qualifications are needed, what type of training is necessary, and the future need of the career they choose. Some other things to consider would be how much money they will make, what is the probability of advancement, and does the career satisfy their need for an enjoyable life.
Effort to write code in Object Oriented Programming Language is high. Because planning should be done before writing every single code.
Software engineering was suggested at a NATO conference in 1968 to talk about the software crisis. “Software crisis” was the name give to problems encountered in the development of large and complex systems . In the early 1970s, notions of structured programming started coming up. In the late 1970s, early
Operating systems work in two ways, by managing the hardware and software resources of the computer. Managing the hardware and software resources, is important because different programs and input methods go through the central processing unit (CPU) and both take up memory, storage and input/output bandwidth for their own purposes. Secondly, providing a consistent application interface, is critical if there is more than one of a specific type of computer using the same operating system, or if the computer’s hardware can be updated. A consistent application program interface (API) creates a way for a software developer to write an application on one computer and know that it will run on another of the same type, even if the memory and storage are different between computers.
