C Programming Language for Beginners

C Programming Language for Beginners C is a programming language invented in the early 1970s by Dennis Ritchie as a language for writing operating systems. The purpose of C is to precisely define a series of operations that a computer can perform to accomplish a task. Most of these operations involve manipulating numbers and text, but anything that the computer can physically do can be programmed in C. Computers have no intelligence - they have to be told exactly what to do and this is defined by the programming language you use. Once programmed they can repeat the steps as many times as you wish at very high speed. Modern PCs are so fast they can count to a billion in a second or two. What Can a C Program Do? Typical programming tasks include  putting data into a database  or pulling it out, displaying high-speed graphics in a game or video, controlling electronic devices attached to the PC or even playing music and/or sound effects. You can even write software to generate music or help you compose. Is C the Best Programming Language? Some computer languages were written for a specific purpose. Java was originally devised to control toasters, C for programming Operating Systems, and Pascal to teach good programming techniques but C was intended to be more like a high-level assembly language which could be used to port applications to different computer systems. There are some tasks that can be done in C but not very easily, for example designing GUI screens for applications. Other languages like Visual Basic, Delphi and more recently C# have GUI design elements built into them and so are better suited for this type of task. Also, some scripting languages that provide extra programmability to applications like MS Word and even Photoshop tend to be done in variants of Basic, not C. Which Computers Have C? The bigger question is, which computers dont have C? The answer - almost none, as after 30 years of use it is virtually everywhere. It is particularly useful in embedded systems with limited amounts of RAM and ROM. There are C compilers for just about every type of operating system.   How Do I Get Started With C? First, you need a C compiler. There are many commercial and free ones available. The list below has instructions for downloading and installing the compilers. Both are completely free and include an IDE to make life easier for you to edit, compile and debug your applications. Download and Install Microsofts Visual C 2005 Express EditionDownload and Install Open Watcom C/C Compiler The instructions also show you how to enter and compile your first C application. How Do I Begin Writing C Applications? C code is written using a text editor. This can be notepad or an IDE like those supplied with the three compilers listed above. You write a computer program as a series of instructions (called statements) in a notation that looks a little like mathematical formulas. This is saved out in a text file and then compiled and linked to generate machine code which you then can run. Every application you use on a computer will have been written and compiled like this, and many of them will be written in C. You cant usually get hold of the original source code unless it was open source. Is There Plenty of C Open Source? Because it is so widespread, much open source software has been written in C. Unlike commercial applications, where the source code is owned by a business and never made available, open source code can be viewed and used by anyone. Its an excellent way to learn coding techniques.   Could I Get a Programming Job? Fortunately, there are many C jobs out there and an immense body of code exists that will need updating, maintaining and occasionally rewriting. The top three most popular programming languages according to the quarterly Tiobe.com survey, are Java, C, and C. You could write your own games but youll need to be artistic or have an artist friend. Youll also need music and sound effects. Find out more about game development. Games like Quake 2 and 3 were written in C and the code is available free online for you to study and learn from it. Perhaps a professional 9-5 career would suit you better- read about a professional career or perhaps consider entering the world of software engineering writing software to control nuclear reactors, aircraft, space rockets or for other safety-critical areas.

3 Examples of How Semicolons Strengthen a Sentence

3 Examples of How Semicolons Strengthen a Sentence 3 Examples of How Semicolons Strengthen a Sentence 3 Examples of How Semicolons Strengthen a Sentence By Mark Nichol Semicolons help clarify construction of sentences. Using the punctuation mark, employed as either a comma on steroids or a strategically flexible period, is usually just one of two or more possible solutions, but though it has a stuffy reputation and many writers are confused about its applications, it often is the best choice. 1. This issue is not cut and dried, it’s actually fairly complicated. This sentence demonstrates the simplest and perhaps most common error related to the role of the semicolon: the failure to use it when when needed in the weak-period function. This pair of independent clauses must be separated by a semicolon: â€Å"This issue is not cut and dried; it’s actually fairly complicated.† Replacing the comma with a dash or beginning a new sentence with it’s are alternative strategies, though the statement does not include a sharp break in thought (which a dash is intended to signal) and does not constitute two distinct ideas meriting separate sentences, so the semicolon is the most suitable solution. 2. For breakfast, he had eggs the way he liked them, over easy, bacon, locally raised, of course, toast, and coffee, which he always stirred exactly 10 times to blend in the milk. This sentence requires semicolons to clearly organize a rambling list of words and phrases that constitute a menu: â€Å"For breakfast, he had eggs the way he liked them, over easy; bacon, locally raised, of course; toast; and coffee, which he always stirred exactly 10 times to blend in the milk.† However, the preparation details can also be presented enclosed in parentheses, which renders semicolons unnecessary: â€Å"For breakfast, he had eggs the way he liked them (over easy), bacon (locally raised, of course), toast, and coffee (which he always stirred exactly 10 times to blend in the milk).† For consistency and to enhance sentence balance and rhythm, better yet, a corresponding detail about the toast should be inserted. 3. The act offers protection from lawsuits arising from monitoring information systems, including employee email, cyberthreat-related disclosures, and sharing of that information with other companies. This sentence requires semicolons because even though â€Å"including employee email† seems obviously related to the preceding phrase, the sentence can also be read as if employee email, cyberthreats-related disclosures, and sharing of that information with other companies are being offered as examples of information systems. Use the stronger punctuation mark in such sentences so that the sentence organization is unambiguous: â€Å"The act offers protection from lawsuits arising from monitoring information systems, including employee email; cyberthreat-related disclosures; and sharing of that information with other companies.† Want to improve your English in five minutes a day?
