Learn the Basics of Computer Programming!

-


To understand the basics of computer programming, you first need to know what is computer programming. Computer programming is defined as creating a sequence of instructions to be carried out by a computer to perform a task. A computer program is similar to a recipe in cooking. In a recipe, there are ingredients and there are instructions that are done to those ingredients. In programming, there are data and there are instructions (called code) that are done to that data. For example, here's a classic egg sandwich recipe: Ingredients 3 large whole eggs 1 slice Canadian bacon 2 slices whole-wheat bread, toasted 1 tomato, sliced Instructions Scramble whole eggs in a bowl Fry in non-stick skillet with olive oil spray Dump onto toast Add bacon and tomato Serve And here is a classic piece of computer programming in a made-up computer language to keep it simple: Data DataItem A DataItem B DataItem C Instructions A = 1 B = 2 C = A + B With the recipe, you first must have your ingredients before you can prepare the meal. In computer programming, you need to tell the computer about your data before it can operate on it. In the above computer programming example, the computer is first notified of 3 data items or storage areas: A, B and C. The computer is then instructed to insert the value of 1 into the 'A' data item (A = 1) and then 2 into the 'B' data item (B = 2). The final instruction is for the computer to now add 'A' plus 'B', which then inserts the value of 3 into the 'C' data item. This is the essence and basics of computer programming.

Google search tips and tricks!

Google Search’s learning curve is an odd one. You use it every day, but still all you know is how to search. But the search engine has plenty of tricks up its sleeve. Here’s an overview of some of the most useful Google search tricks, from basic tips to new features just recently released. 1. Use quotes to search for an exact phrase. This one’s a well-known, simple trick: searching a phrase in quotes will yield only pages with the same words in the same order as what’s in the quotes. It’s one of the most vital search tips, especially useful if you’re trying to find results containing a specific a phrase. 2. Use an asterisk within quotes to specify unknown or variable words. Here’s a lesser known trick: searching a phrase in quotes with an asterisk replacing a word will search all variations of that phrase. It’s helpful if you’re trying to determine a song from its lyrics, but you couldn’t make out the entire phrase (e.g. “imagine all the * living for today”), or i...

CSS3 is the latest standard for CSS The new features of CSS 3 uncover a lot of new possibilities and are beginning to be more widely used. Don’t get too excited though because it is not fully supported by all browsers. But this doesn’t mean you shouldn’t use it at all… Because these new features are not supported by some browsers (*cough* IE *cough*) you shouldn’t rely on CSS 3 for layout purposes. Instead you should use these new techniques to enhance your design for those viewers using the compatible browsers.< Below are descriptions of some of the most basic new features: Text Shadow Text shadow does exactly what it sounds like. It adds a shadow to your text. Border Radius Border Radius allows you to add rounded corners to an object. You can also specify a different size for each corner. Box Shadow Box shadow is similar to Text shadow except it’s added to an object and not text. Again, those are just the most basic of features. There are a lot of other...

Many people are curious as to what exactly the differences are between PDF and EPUB. Th Epub vs Pdf ey can’t quite understand why everyone seems so excited for EPUB. What’s so great about that format as opposed to all the others? In fact, people are excited about EPUB in particular over other reflowable eBook formats because it’s the first open eBook standard based on existing specifications with actual industry support. In the article, I’d like to have simple introduction of PDF and EPUB eBook formats, then make comparison  between  PDF and EPUB.  Definition about EPUB and PDF EPUB, called electronic publication format, is probably the most common of all the formats and is widely supported across all platforms. Most e-Readers like Apple’s iBooks, Barnes & Noble’s Nook, Adobe Digital Editions, Aldiko on Android among others (nearly 300) support .EPUB files. The EPUB format is an open standard. That means it is free and publicly available though there are specifi...
