What Are Variables in Computer Programs

What Are Variables in Computer Programs A variable is a way of referring to a storage area in a computer program. This memory location holds values- numbers, text or more complicated types of data like payroll records. Operating systems load programs into different parts of the computers memory so there is no way of knowing exactly which memory location holds a particular variable before the program is run. When a variable is assigned a symbolic name like employee_payroll_id, the compiler or interpreter can work out where to store the variable in memory. Variable Types When you declare a variable in a program, you specify its type, which can be chosen from integral, floating point, decimal,  boolean or nullable types. The type tells the compiler how to handle the variable and check for type errors. The type also determines the position and size of the variables memory, the range of values that it can store  and the operations that can be applied to the variable. A few basic variable types include: int - Int is short for integer. It is used to define numeric variables holding whole numbers. Only negative and positive whole numbers can be stored in int variables.   null - A nullable int has the same range of values as int, but it can store null in addition to whole numbers. char - A char type consists of Unicode characters- the letters that represent most of the written languages.   bool - A bool is a fundamental  variable type that can take only two values: 1 and 0, which correspond to true and false.   float, double and decimal - these three types of variables handle whole numbers, numbers with decimals and fractions. The difference between the three lies in the range of values. For example, double is twice the size of float, and it accommodates more digits. Declaring Variables Before you can use a variable, you have to declare it, which means you have to assign it a name and a type. After you declare a variable, you can use it to store the type of data you declared  it to hold. If you try to use a variable that hasnt been declared, your code wont compile.  Declaring a variable in C# takes the form: data_type variable_list; The variable  list consists of one or more identifier names separated by commas. For example:   int i, j, k;   char c, ch; Initializing Variables Variables are assigned a value using an equal sign followed by a constant. The form is: data_type  variable_name value; You can assign a value to a variable at the same time you declare it or at a later time. For example:   int i 100;   or   short a;int b;double c;   /*actual initialization */a 10;b 20;c a b; About C#   C# is an object-oriented language that does not use any global variables. Although it could be compiled, it is almost always used in combination with the .NET framework, therefore applications written in C# are run on computers with .NET installed.

Assessing the Potential Risk of Earthquakes, Volcanoes, and Tsunamis Essay

Assessing the Potential Risk of Earthquakes, Volcanoes, and Tsunamis - Essay Example The reason behind the occurrence of earthquakes is noted to be the excessive energy that has been accumulated within the layers of earth. Notably in the case of Dallas, Texas, it could be said that the energy has been releasing through the occurrence of earthquake every year which makes the probability of the earthquake predictable but with relatively lesser magnitude. Considering the four seasonal-geographical conditions of Dallas, it can be said that the delocalization of crust is less accumulating. The occurrence of earthquakes at Dallas has projected the duration of thunderstorms much longer. Also, the hurricanes and snowstorms are predictable at Dallas mainly because of the occurrence of earthquake that releases energy off the earth surface displaying disturbance of the earth crust to minor extent (Resources for Environmental Literacy, 2007). The generation of Tsunamis is due to the disturbance of the large amount of water waves underneath. This may happen due to the eruption of volcano, land sliding or the contact of tectonic plates of the earth. This may affect the waves of water which may travel 600mph. Considering the case of Tsunami in Dallas, Texas, there has been no activity on the active tectonic layer of Dallas which makes Dallas a less vulnerable region for the generation of Tsunami. The active tectonic plates in Texas in whole is considered as an out of alert zone for tsunami as per the predictions. Tsunami’s generation is more likely to take place at the active tectonic layer of Mexico and the near coastal areas of United States (Hasiholan, 2007). The eruption of volcano takes place when about 17 layers of earth are dismantled and or broken. The layers of earth are then set beneath the ground usually on the hotter layer of the earth crust. Earth mantle is the hottest temperate area which makes the stones and other earthy elements to

FEASIBILITY ANALYSIS - Essay Example The sources of funds will be the share of capital by the three investors. To meet the legal aspects of the business as a General Partnership, one of the three investors will be a national of UAE with around 51 percent of the shares. The shares of the other two investors will be equal. In this section, the feasibility analysis of HealthPoint has been done by analyzing the market and competition situation. To analyze the market, STP approach and BCG matrix methodologies have been used whereas, to analyze the competition situation, Porter’s Five Forces analysis has been conducted. Finally, a survey has been developed which will be used to analyze the feasibility of the proposed business. The UAE food market can be segmented into three major segments including the Retail Outlets (targets the resident expatriates community and covers 80 percent of the population base), Restaurant (Targets the tourists and the visitors community along with the health concerned resident expatriates) and other Market Outlets (such as ship chandlers, catering etc) (Rahman). Since our proposed venture falls in the category of restaurants therefore, only the market segments for this category will be considered. The target market for the proposed venture will be the health conscious people, professionals who seek to eat healthy food during their lunch breaks and workplaces and students who are concerned about their healthy diet plans. In order to attract the target market, the restaurant will be positioned as a healthy-food outlet rather than a food point. Since various Western, Arabic and other small or big outlets of domestic and international brands are operating in Abu Dhabi therefore, there is a strong competition among companies. Because of the tough competition the market shares of each company is very low however, based it has found that because of

Wine of Barolo of the Nebiolo Grape Essay Example | Topics and Well Written Essays - 1000 words

Wine of Barolo of the Nebiolo Grape - Essay Example This means that it has an astringent taste. As such, when tasting the grape, one could experience the strong nature of the grape’s juice. Different people could actually have different interpretation of their tasting experience. Some utter that the grape’s juice is too strong. Others say it is soft and rich. In such case, the people’s reactions depend on their preference with regard to wine grape varieties. The grape’s name has actually two possible origins. The first thought is based on the grape’s appearance when it is fully ripe. When fully ripe, the grape gives a frosted or foggy look (â€Å"Nebbiolo†). The Italian term for fog is nebbia (â€Å"Nebbiolo†), thus, the name Nebbiolo. Nonetheless, it is also possible that the grape’s name is simply taken from the Italian word nobile which means noble (â€Å"Nebbiolo†). Irregardless of the two probable origins of the grape’s name, what is sure is that Nebbiolo is fa mous to be a good wine grape variety. It is even one of the grape varieties that is most treasured by wine growers not just in Italy but also in the different parts of the world. The Nebbiolo grape is actually hard to grow and cultivate according to vineyardists (â€Å"Nebbiolo†).... It is made from one hundred percent Nebbiolo grape. The label DOCG means that is a wine of highest category. It also indicates that is both controlled and guaranteed by the Italian government (Nowak and Wichman 87). In buying such kind of wine, the buyer could be assured of the wine’s quality. In Italian, DOCG refers to Denominazione di Origine Controllata e Garantita. In English, it means Controlled and Guaranteed Denomination of Origin (Nowak and Wichman 87). Wines in Italy are actually subjected to DOC appellation system (Katsigris and Thomas 262). In this system, wine products are labeled according to its level (DOCG being the highest grant). The labeling depends upon the result of the official taste test which is conducted by the Italian government before the wine is permitted to be sold in the market (Katsigris and Thomas 262). The system builds risks and incentives which encourage wine producers to make wines of good quality (Katsigris and Thomas 262). In this sense, th e Italian government is strict with regard to their wine production process. This is to say that the wine-making process is a big issue in Italy. In another aspect, the Barolo DOCG is actually called as the â€Å"Wine of Kings and Kings of Wines† (Gibson 181). This implies that the Barolo wine is the best wine in Italy. The wine of such kind is known to have been barrelled for several years. To note, extended bottle aging actually affects that taste of the wine. Most often, wines which are barrelled for a minimum of two to three years offer a very good taste. Laws in Italy actually require Barolo wines to be aged in wood for at least two years (Bespaloff 58). Longer barrel gives the wine a woodier and mature taste (Bespaloff 58). Stated otherwise, the

Narrative report - Essay Example Mark Henderson had been informed by his daughter, Selena Henderson’s school that she had been posting on obscene items on the social media. Mark warned her and asked her to desist from doing so. His admonition had no effect upon Selena, and the school once again reported similar behavior on her part to Mark. The infuriated Mark accosted her and gave her a sound thrashing. While doing so, he became enraged to the extent that he commenced to strangle her. This was being witnessed by his wife and his son. However, his wife stopped him from strangling her. Daniel T Satterberg, the Prosecuting Attorney for King County had accused Mark Henderson of the crimes of assault in the second degree – domestic violence, and assault in the third degree – domestic violence. These were based on the same sequence of acts or conduct that were interrelated or forming the components of a common plan. These were assault in the second degree – domestic violence, and assault in the third degree – domestic violence. He further stated that the defendant Mark Henderson, in King County, Washington, on 23 January 2014 had assaulted Yvonne Henderson by choking her. This was contrary to RCW 9A36.021(1)(9), and against the dignity and peace of the State of Washington. In the courtroom, the pressing judge, Timothy A Bradshaw, exhibited adequate control.

As a result, the attorneys, prosecutors, court clerks, and other concerned individuals had to function in an optimal manner. The defendant Henderson pleaded guilty with respect to the charges framed against him. Specifically, he conceded in writing that the he

Effects of Mass Media Violence on Violent Behavior Research Paper

Effects of Mass Media Violence on Violent Behavior - Research Paper Example Therefore, a foundation must be established on which the arguments of both sides can be viewed impartially, and through which we can reach a valid understanding of the issue of mass-media violence. What makes this difficult is that the criteria of judgment for the question is political, based on the vision or ideal of society that one wants to see manifest. To illustrate this, it is important to start with the opposite, teachers of non-violence such as the Dalai Lama, Mahatma Gandhi, Nelson Mandela, Dr. Martin Luther King Jr., etc. and consider what their ideals of a non-violent society are, as well as why they consider violence so fundamental to be opposed. For example, if we judge the question of mass-media violence against the goals of Satyagraha as taught by Mahatma Gandhi, and the vision of society he sought to develop, we might have a very different conclusion than if we judge the question by the values of Bush, Cheney, and the administration that led the United States to war & torture in Iraq and Afghanistan. To reduce this division further, a society that commands the world’s largest military, has over 800 foreign military bases, and is conducting wars on multiple battlefronts might not only have a different goal as a society than a country like Tibet, once a Buddhist kingdom with thousands of monasteries ruled by a reincarnate monk, but the societies might also have very different actual perceptions of what violence is, and tolerance to it. Jains in the ancient world were renowned for sweeping the road in front of themselves when walking and wearing masks to insure that they did not injure any insect while traveling or breathing. A society based on this level of sensitivity to violence may view mass-media imagery of violent behavior in a very different way to our society that has been desensitized to it for years. Thus, we must approach this as
