Here is an example of programming comments in the C programming language. In C, the two slash symbols "//" known as a forward slashes, are used. With the comments, a person can read the code and know what is going on.
// This is a comment, ignored by the computer
int main(void) { // Here the starting point of the program is defined
Sometimes, a programmer may need to remove something from the code, but for many different reasons, they may not want to just simply delete it. An easy solution is to use the comment symbol. The computer will think that the code is just comments, rather than actual code, but the programmer will still be able to see it and read it.
Here is an example of that in the Perl programming language. In Perl, the "#" symbol is used for comments, instead of forward slashes "//" like in the C (programming language).
$name = "Sam"; #we set the name variable to be Sam
$age = 14; #We set the age to be 14
Computer programmers make mistakes when writing codes. The mistakes are called bugs and cause the program to follow the wrong instructions. Debugging is the process of finding and fixing the mistakes. To debug code is to find such mistakes.
There are many debugging methods. Software such as text editors and IDEs have tools that can detect specific mistakes in the codes before the program is executed. Programmers can also use programs called debuggers. A debugger can run a program step by step and track how values of specific variables change when the program is running. Programmers can use a debugger to find where the mistake happened in the code.
BASIC
BASIC is one of the first programming languages ever to be created. It was first used as a programming language on console computers. The name is an acronym (a word made from other words) that spells Beginner's All-purpose Symbolic Instruction Code.
A specialized version of BASIC is Blitz BASIC. It is specially for coding games.
It was designed by John Kemeny and Thomas Kurtz in 1963. It was based in part on Fortran and made to follow these eight principles:
The creators made the compiler free of charge to make programmers interested in using the language. Since the creation, many other compilers and interpreters have been made so users can make their programs.
for x=9/3*9+9"print x"next x
Code prints number "36" to screen.
Mayon Volcano
The Mayon Volcano, also known as Mount Mayon, is an active volcano in the province of Albay, on Luzon island in the Philippines. It is a part of the Pacific Ring of Fire. It is one the most active and dangerous volcanoes in the Philippines. Mount Mayon is high, and it is famous for it's "perfect cone" shape, which attracts tourists. In 1938 the mountain was declared a national park. It was reclassified and renamed as "Mayon Volcano Natural Park" in the year 2000. The name Mayon is from the Bicol word "magayon" meaning beauty.
Grease
Grease refers to a number of things:
Visual Basic .NET
Visual Basic .NET is the second series of Microsoft's Visual Basic series. It is sometimes shortened to VB.NET. It is an IDE (Integrated Development Environment) and it includes an easy 'drag-and-drop' interface. It can make complete programs for Windows very easily.
It was first released in 1992 by Microsoft. Visual Basic is a simple way to make programs for Windows. It started as "Project Ruby" by Alan Cooper and then was sold to Microsoft. The system is built loosely on the original BASIC programming language released in 1963 and it can 'Test' programs in real-time, error checking them in a user-friendly way.
This package is the 'backbone' of Visual Basic .NET. When applications are created, the Windows Installer includes the framework with it. It includes all the items needed to run the VB.NET applications that have been made.
Visual Basic was first released in May 1991 for Windows. Many versions have been released since then. These are listed below:
This is a free version of Visual Basic 2010 released officially from Microsoft. It is aimed at encouraging more newbie programmers to try the series. The program can be downloaded from Microsoft's Website.
Visual Basic .NET uses many controls which can be added to the forms or windows in the application. Other developers can create controls for applications, not just the ones that Microsoft include.
The following example makes a program window pop up that says "Hello World" and has a button that says "OK" used to close the window:
Temperature record of the past 1000 years
People measure modern temperature records using instruments. Records only cover the last 150 years or so. The temperature record of the past 1,000 years or more is found by using data from what are called "climate proxy" records.
Proxies can be anything which relates to climate. Short term autobiographies often talk about the weather in past eras, and we do have some autobiographies from 2000 years ago. There are also tree rings and other methods which go back about 20,000 years. Further back still, there is evidence from geology, the record of the rocks. However, this page is just about the last 1000 years.
We are fairly sure there was a warm period about 1,000 years ago, and a cold period about the 17th century. Even in the 19th century people skated on the Thames in wintertime.
Although people today talk about climate change as if it were entirely man-made, this is not the complete picture. It is quite certain that climate has always been changing on Earth. Man-made changes are on top of changes which occur naturally. The Milankovich cycle is an important factor in these changes, and there are also changes in the heat put out by the Sun.
Camping
Camping is a leisurivity, usually during summer when school children are on holiday, where people leave their homes and spend one or more nights outdoors. Usually they seek nature, adventure, or a different environment. They may sleep in a campervan or trailer, a tent, or in the open air in good weather. Winter camping is less common but in some parts of the world, tents are people's homes year around. Rich people began camping for fun in the early 20th century. When more people could afford it, many more did it.
When camping, people usually prepare food to eat that is easy to make. If they were hunting or fishing, they may cook the animal or fish they caught over a campfire.
Dangers can arise, such as wild animals or illness from drinking unclean water.
New Guinea
New Guinea is a big island north of Australia. It is the second largest island in the world.
On the east side of New Guinea is the country Papua New Guinea. On the west side of the island are the Indonesian provinces of Papua and West Irian Jaya.
About 6.9 million people live on the island.
New Guinea is also very important for its nature and biology, because there are many different animals.
Honda
Honda is one of the largest engineering company from Japan created on 24 September 1948. It is well known for making automobiles and motorcycles. Although Honda started in Japan, it now has many factories in other countries that includes the United States, Canada, Brazil, Thailand and China. Honda sells a luxury line of cars in the United States with the Acura name.
Some of the automobiles that Honda makes include the:
Some of the cars Honda has made in the past are:
Honda also makes ATVs. Honda is also known for participating in a very wide range of motorsport events, including Formula One , MotoGP, LeMans, IRL and others.
Honda also makes small engines for chainsaws, lawnmowers and leaf blowers.
Honda does a lot of research on humanlike robots. Honda built Asimo, a robot that can walk, talk, dance, carry things and answer questions. These are not yet for sale in the United States.
Honda also creates a, jet, known as the HondaJet. It is not often seen in the United States
Camelid
Camelids are a group of even-toed ungulate mammals. They form the family Camelidae. There are six living species of camelids.
