In a previous report, we introduced the automation of some tasks with batch files MS-DOS. In this report, we will introduce the program and describe how they could use to control the operation of your PC. In general, computer novices are not thinking about the control of the PC. The new computer users are often eager to learn more about how it works. On the other hand it is quite possible that he was surprised to discover that the laptop program increases or computer information as complete and can help reduce the fear associated with the use of a new laptop or computer.
Programming a personal computer is the creation of a sequence of instructions that allow the PC to complete a thing. 1 People who plan to computers (called programmers) use a programming language to communicate with a computer system. You may have heard of some of these languages ??in the past, including Visual Basic, C + + or Fortran. There are hundreds of other programming language, and neither one is better than the other. Most of them are able to do exactly the same tasks and achieve exactly the same goals. A developer chooses a language for a simple choice.
Each and every one of these languages ??differ in the way of communicating with a PC, even so, and the commands that follow are quite particular. Not a single command of a language can be exchanged with the commands or language of another. But they all could be used to control a personal computer.
Now it will be impossible to teach you how to plan for any of the languages ??in one language. But we can still introduce some of the most fundamental ideas of programming – starting with the commands we talked about earlier. Commands are the instructions a computer follows to perform an action. 2 To make them work within a system, programmers assign commands to objects such as buttons as an example.
The commands in a program are pretty useless unless you have some information to act as developers whether the programs provide some data to work with (names or numbers, for example) or make the program believe it data about itself. Sometimes, the data comes from an external source, such as web or the computer that the program runs on. The data received by a plan called the data input and generating output system is called.
Other times, the information is unknown. If the work system has a simple algebraic equation such as “x + y = five,” variables “x” and “y” would be unknown pieces of information. Or if a program is to calculate a date “x” days from now, the variable “x” would be an unknown piece of information until you inform the plan of what “x”. In programming, it is occasionally necessary to work with unknown pieces of data.
That’s when conditions are available at hand. Conditions enable a computer to perform an action based on the results of a previous command.three Using this type of instruction could be entrusted to a system to a factor if the “x” variable in our example the latter was found 7 days, and then make a different factor if the variable was 3 days.
Commands, data, variables and conditions to help develop programs probably easier and you will surely find many more components of any programming language. But when written in a programming language and compiled to develop an executable file (a file that ends with a. Exe), become a software application.
As mentioned earlier, you can use a programming language to control your PC. Using basic commands, you can set your laptop or computer to perform mathematical tasks, fill web forms, compose email and send it, or any number of other items. If you happen to be interested, can come through Visual Basic is one of the easiest programming languages ??to learn. Visual Basic is a programming language, object-oriented code automatically greatly from a developer plan minutes drag a button on a screen.
