Introduction to C language

Watch the video and put the words into the gaps in the text

Welcome to these series of videos that will show you how to program in C. The C language is one of the oldest (1)_____ which, with its great power, ability to manipulate (2)____ in (3)_____, and basic constructs for (4)_____ is used by programmers around the world and at different (5)____ of experience. In this video particularly, we will address a general view of the C language and its (6)_____ and purpose in the modern world of computers and engineering. The C language is currently used significantly to program (7)____ systems, cell phones, medical devices, PCs, etc. Graphic (8)____ Interfaces for utility software 3D graphics, game engines, Artificial (9)____ also known as AI for search engines, (10)____ and drivers for electronic devices, other programming and (11)____ languages, code optimization, operating (12)____ for electronic devices containing processors within: vehicles, appliances, printers, photocopy machines, etc.       All technologies are based on previous technologies. The C language is one of those technologies that does not (13)___ since it is sufficiently abstract to be understood in an (14)___ and conceptually general way without needing the knowledge of electronics of the specific features of  their (15)___ also known as (16)___ for machine instructions of a given (17)___. It also avoids high-level concept constructs inherent in its syntax, such as: classes, (18)____, (19)___ and data structures.          In C you can build the aforementioned concepts that are not included in the (20)___ of the language. Usage of the C language is important, so much so that even language (21)____ of higher abstraction level such as: (22)____, Lisp, Java and C++ can be programmed in C. If you use the GNU Linux operating system you know that to install several utility packages they must be compiled as C (23) ____ code files.	bits

This is multi-touch (1)___ which is a multi-finger, (2)___ that has been bouncing around the world of computer science since the 1980s. Jefferson Han: “This is a multi-touch (3)____ and multi-touch which generally means multi-point input devices are about allowing more than one input to be in (4)____ at a time”. NYU computer scientist, Jeff Han, built huge multi-touch (5)____ for (6)____ and military clients through his company “Perceptive Pixel”. In fact, multi-touch is swiftly becoming the hard interface for electronic (7)_____. Jefferson Han: “Multi-touch first of all allows for direct (8)_____. It means you are actually contacting not through an (9)____ but actually on the (10)_____ itself. It's a direct manipulation, in fact. Two, it means that I can do more than one point at a time. I can actually use two or three which means I can manipulate more things at a time. With the mouse, you can only manipulate one or two things at a time”. But where Microsoft Surface Computer truly gets mind blowing is how it interacts with other devices. The Surface Computer uses a series of (11)____ cameras to literally see what is on its tabletop. Nigel Keam: “What we’re able to do is also have interaction with objects on the (12)____. So when we place an object on the surface, the cameras can recognize what that object is and allow us to interact directly with the object that we've just placed on the surface. We see this is a whole new category, a complete new (13)____ for computers”.	input device

Glene Derene: “Here we have a (14)___ camera and a lot of wireless (15)____ is built into the Surface computing platform. And it's evolving into, in the devices such as this camera. So here, we're going take a picture of my colleague Eric. And we can then just put the camera right on the device and use that picture, which is, I think, enormously flattering, of our friend, and really, really blow it up for maximum embarrassment. We have a cellphone and all the wireless linking is going on behind the scenes in the table. So you can take your photo and then just (16)____ put it on your wireless device and then take it with you. Now you've basically taken two devices and without having to (17)____ them into a computer or sync them up, you've (18)____ content from one to the other”. Although surface computing may eventually find a place in the home, Microsoft initially plans to sell the devices to (19)___ partners such as T-Mobile, Harrah's Casinos and Starwood hotels. The 5000 to 10,000 dollar machines will start showing up in local (20)____ as early as the end of 2007. But where is all of this leading? Computer scientists see a near future of (21)____ where people are surrounded by (22)____ surfaces. Nigel Keam: “It may be the surface of your kitchen table or it can be in front of your television and it can help you to control your television as the ultimate unlosable (23)___”. Jefferson Han: “Eventually, of course, this will trickle down and I do – I am very positive and I firmly believe that this kind of thing will be in that near future where we have wallpaper displays in every hallway, every (24)____, every surface starts to become an interface of a computer and in order for that to happen, we need (25)____ like this”.    2. Answer the questions. 1.     What device is this video about? 2.     Does the Surface Computer use a series of infrared cameras? 3.     Can the camera recognize the object placed on the surface?     4.     To whom does Microsoft plan sell the devices?      5.Every surface starts to become an interface of a computer, doesn’t? 3.  Mark the following statements as True or False. 1.     The multi-touch technology has been bouncing around the world of computer science since the 1970s. 2.     Jeff Han built huge multi-touch displays for corporate and military clients through his company “Microsoft”. 3.     A direct manipulation means a contact on the graphics itself. 4.     You can’t manipulate more than two things at a time with the mouse. 5.     There is a lot of wireless functionality built in to the Surface computing platform. 6.     In this video the computer scientists transfer a photo from one camera to another.  7.     Surface computing may find a place only in the banks. 8.     The computer scientists think that people will be surrounded by intelligent surfaces in near future. 9.  With the help of Microsoft Surface Computer you can control your television.	plug
