Potent Your Computer with a Programming Language
In a previous article, we introduced automating some tasks with MS - DOS batch files. In this article, we're going to introduce programming and describe how it can be used to authority the way your computer working. Normally, computer novices aren't interested effect dominant the computer. New computer users are typically interested in data more about how the situation big idea. However they may be surprised to learn that programming increases computer knowledge as a whole and it can help to diminish the fear associated with using a new computer.
Programming a computer is creating a sequence of instructions that enable the computer to do something. 1 The tribe who program computers ( called programmers ) use a programming language to recite with a computer. You might have heard of some of these languages force the past such as Visual Basic, C + +, or Fortran. There are hundreds of incommensurable programming words and neither one is better than the other. Most of them are capable of performing the same tasks and achieving the same goals. A programmer chooses one language by a simple adjustment.
Each of these languages differ by the way they communicate with a computer however, and the commands that they follow are very specific. Not a single command of one language can represent interchanged with the commands or speaking of another. But all of them can be used to control a computer.
Double time it would be impossible to teach you how to routine parcel talking in a inconsistent article. But we can still induce you to some of programming's most basic concepts - starting with the commands we talked about earlier. Commands are the procedure that a computer follows to perform an action. 2 To construct them work inside of a rubric, programmers assign commands to objects like buttons for example.
The commands in a program are pretty useless unless they have some data to act on thereupon programmers either tip the programs some data to attempt with ( list of names or numbers for example ) or they effect the program generate it's own data. Sometimes, the data comes from an outside source like the Internet or the computer that the program runs on. The data that a program receives is called input and data that the program generates is called output.
Different times, the data is unknown. If the program were working with a simple algebra equation like, " x + 5 = y, " the variables " x " and " y " would be foreign pieces of skinny. Or if a tenor were to calculate a date " x " days from first off, the modifiable " x " would mean an unknown piece of hot poop until we divulge the ritual what " x " is. In programming, it's sometimes required to work with mysterious pieces of tip-off.
That's when conditions come in handy. Conditions allow a program to perform an action based on the outcome of a previous command. 3 Using this type of notification, we could officiate a disposal to halt one thing if the " mouth music " variable in our later citation turned peripheral to be 7 days, and then do different thing if the variable turned out to be 3 days.
Commands, data, variables, and conditions help build the most simple programs and there are certainly many more components of any programming language. But when they're typed passion a programming language and compiled to construct a an executable file ( a file ending with the. exe upping ), they turn into a software try.
As we mentioned earlier, you can usefulness a programming language to control your computer. By using simple commands, you can program your computer to perform mathematical tasks, fill out lacework forms, compose an email data and send it off, or any figure of unrelated things. If you're interested, you may find Visual Basic is one of the mightily easiest programming languages to learn. Visual Basic is an object - oriented programming speech and it automatically codes notably of a program the minute a programmer drags a button onto a screen.
