Pascal programming language was designed in 1968, and published in 1970. It is a small and efficient language intended to encourage good programming practices using structured programming and data structuring. Pascal was developed by Niklaus Wirth. The language was named in honor of the French mathematician and philosopher Blaise Pascal. In 1641, Pascal created the first arithmetical machine. Some say it was the first computer. Wirth improved the instrument eight years later. In 1650, Pascal left geometry and physics, and started his focus towards religious studies. A generation of students used Pascal as an introduction language in undergraduate courses. Types of Pascal have also frequently been used for everything from research projects to PC games. Niklaus Wirth reports that a first attempt to merge it in Fortran in 1969 was unsuccessful because of Fortran's lack of complex data structures. The second attempt was developed in the Pascal language itself and was operational by mid-1970. A generation of students used Pascal as an introductory language in undergraduate courses. Pascal, in its original form, is a Procedural language and includes the traditional like control structures with reserved words such as IF, THEN, ELSE, WHILE, FOR, and so on. However, Pascal has many data structuring and other ideas which were not included in the original, like type definitions, records, pointers, enumerations, and sets. The earliest computers were programmed in machine code. This type of programming is time consuming and error prone, as well as very difficult to change and understand. Programming is a time-consuming a process. More advanced languages were developed to resolve this problem. High level languages include a set of instruction...

... the standards or how it compares to other available implementations. Pascal is still used today, both as an educational tool for programming, as well as a liable language for industrial, commercial, scientific, shareware and freeware applications. The Pascal language is available on a number of different platforms, both commercially and through open source. Pascal is a useful programming language which has been used for decades now. It continues to grow but is not the most effective programming language in my opinion. It has a great history and will be remembered in computing and programming history for all ages and will continue to teach people a different way of programming. Thank you for reading my essay.

This section outlines and describes the various elements of the program logic model (see Figure 2). Our logic model is an important evaluative tool as it helps to explain the ideas behind the development of the DCD guidelines and the reasons why DCD programs will lead to positive outcomes in deceased organ donation.
Imagine being forced into a room with a hundred others that you don’t know; you are all of different race, religions and economic backgrounds. Now suddenly you are being told to undress and shower. After the shower you are now being sent to the next room still naked and wet. People around you begin to panic, others cry, you just stand there confused in the middle of the chaos. Everything gets quiet when you hear footsteps above you, you see a quick glimpse of light then the room quickly fills with the Zyklon B-gas that the Nazi Army just dropped into the room. People around you are now trying to dig their way out while ripping off fingernails and scratching into the walls, some are huddled in corners with their family members or their children simply begging for the end to come quickly for them. At this moment you now understand their panic and painful pleas for the end. As your breathing begins to weaken and your body is ready to collapse you ask yourself, “How did I get here, How did any of us get here?” You are standing there waiting for the end because of the T4 Program created by Adolf Hitler and these are the experiences that thousands had to face when they were forced into the extermination camps.
Yang Hui has been found to be the oldest user of Pascal’s Triangle. But it is Blaise Pascal who around the year 1654 was credited for his extensive work on the many patterns of this triangle. Because of this people began to call it Pascal’s Triangle.
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.
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.
Occupations in the field of computer science are considered to be “male” jobs. Women are increasingly less likely to enter the field than in years past. However, two of the first people that we were introduced to in our textbook as key people in the history of Computer Science are Ada Augusta and Grace Murray Hopper. The page limits of this paper do not allow the author to adequately describe all of the contributions that Grace made to Computer Science. Instead, you will be introduced to Grace Hopper and how her pioneering work on the Mark I continue to influence women and the world of computer science.
Summary of Readings (10 lines) Rheingold explores the problems of interactions within online networks, particularly in relation to social media sites. With social networking users can connect and share information in an expansive number of ways with people all over the globe. Kallaway, Learning to Code: When It Gets Dark, faced challenges with coding and sometimes want to give up; however, he keeps pushing himself and uses the techniques in learned by reading Resistance by Steven Pressfield. Farag, Please Don’t Learn to Code, explains that coding isn’t for everybody.
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.
Computer engineering started about 5,000 years ago in China when they invented the abacus. The abacus is a manual calculator in which you move beads back and forth on rods to add or subtract. Other inventors of simple computers include Blaise Pascal who came up with the arithmetic machine for his father’s work. Also Charles Babbage produced the Analytical Engine, which combined math calculations from one problem and applied it to solve other complex problems. The Analytical Engine is similar to today’s computers.
Many different types of programming languages are used to write programs for computers. The languages are called "codes". Some of the languages include C++, Visual Basic, Java, XML, Perl, HTML, and COBOL. Each of the languages differs from each other, and each is used for specific program jobs. HTML and JAVA are languages used to build web pages for the Internet. Perl and XML can produce codes that block students from getting on certain inappropriate web pages on their school server. One of the most prominent programming languages of the day would have to be C++.
The fist computer, known as the abacus, was made of wood and parallel wires on which beads were strung. Arithmetic operations were performed when the beads were moved along the wire according to “programming” rules that had to be memorized by the user (Soma, 14). The second earliest computer, invented by Blaise Pascal in 1694, was a “digital calculating machine.” Pascal designed this first known digital computer to help his father, who was a tax collector. Pascal’s computer could only add numbers, and they had to be entered by turning dials (Soma, 32). It required a manual process like its ancestor, the abacus. Automation was introduced in the early 1800’s by a mathematics professor named Charles Babbage. He created an automatic calculation machine that was steam powered and stored up to 1000 50-digit numbers. Unlike its two earliest ancestors, Babbage’s invention was able to perform various operations. It relied on cards with holes punched in them, which are called “punch cards.” These cards carried out the programming and storing operations for the machine. Unluckily, Babbage’s creation flopped due to the lack of mechanical precision and the lack of demand for the product (Soma, 46). The machine could not operate efficiently because technology was t adequate to make the machine operate efficiently Computer interest dwindled for many years, and it wasn’t until the mid-1800’s that people became interested in them once again.
The history of the computer dates back all the way to the prehistoric times. The first step towards the development of the computer, the abacus, was developed in Babylonia in 500 B.C. and functioned as a simple counting tool. It was not until thousands of years later that the first calculator was produced. In 1623, the first mechanical calculator was invented by Wilhelm Schikard, the “Calculating Clock,” as it was often referred to as, “performed it’s operations by wheels, which worked similar to a car’s odometer” (Evolution, 1). Still, there had not yet been anything invented that could even be characterized as a computer. Finally, in 1625 the slide rule was created becoming “the first analog computer of the modern ages” (Evolution, 1). One of the biggest breakthroughs came from by Blaise Pascal in 1642, who invented a mechanical calculator whose main function was adding and subtracting numbers. Years later, Gottfried Leibnez improved Pascal’s model by allowing it to also perform such operations as multiplying, dividing, taking the square root.
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.
If the nineteenth century was an era of the Industrial revolution in Europe, I would say that computers and Information Technology have dominated since the twentieth century. The world today is a void without computers, be it healthcare, commerce or any other field, the industry won’t thrive without Information Technology and Computer Science. This ever-growing field of technology has aroused interest in me since my childhood. After my twelfth grade, the inherent ardor I held for Computer Science motivated me to do a bachelors degree in Information Technology. Programming and Math, a paragon of logic and reasoning, have always been my favorite subjects since childhood.
First of all I had no much computer programming skill from the past , but I do have some short-term programming courses completion. of course the basic idea from the past about python language programming is a big deal to me to prepared myself early for this class. Otherwise not easy to find out exactly what is going on around computer language program; programming a computer is not so simple and controlled within a short period of time, computer programming is need big time and a lot of effort.
