Run the Program. Open the output using Window-Output. Then go to Edit-Show clipboard then save the file with any other name Then open My computer/This Pc.Click on Local disk (C:)-TurboC4-TC-BIN and right click on the name of the file select Edit the file will open in Notepad Then save the file as per your requirement using Save As option.

1. Well one fix for this issue in Turbo C is to find the 'uninstall' option and use it. Alternatviely go to program files folder and find the turbo c folder. Choose 'delete' then go to the recylce bin and choose 'empty' - click yes when prompted 'do you want to permanently delete turbo c' Then go and get Code::Blocks.
2. As in the title. How can I clear console in C? C doesn't even have the concept of a console. The program could be printing to a printer, outputting straight to a file, or being redirected to the input of another program for all it cares.

The C++ standard libraries provide an extensive set of input/output capabilities which we will see in subsequent chapters. This chapter will discuss very basic and most common I/O operations required for C++ programming.

C++ I/O occurs in streams, which are sequences of bytes. If bytes flow from a device like a keyboard, a disk drive, or a network connection etc. to main memory, this is called input operation and if bytes flow from main memory to a device like a display screen, a printer, a disk drive, or a network connection, etc., this is called output operation.

I/O Library Header Files

There are following header files important to C++ programs −

The Standard Output Stream (cout)

The predefined object cout is an instance of ostream class. The cout object is said to be 'connected to' the standard output device, which usually is the display screen. The cout is used in conjunction with the stream insertion operator, which is written as << which are two less than signs as shown in the following example.

When the above code is compiled and executed, it produces the following result −

The C++ compiler also determines the data type of variable to be output and selects the appropriate stream insertion operator to display the value. The << operator is overloaded to output data items of built-in types integer, float, double, strings and pointer values.

The insertion operator << may be used more than once in a single statement as shown above and endl is used to add a new-line at the end of the line.

The Standard Input Stream (cin)

The predefined object cin is an instance of istream class. The cin object is said to be attached to the standard input device, which usually is the keyboard. The cin is used in conjunction with the stream extraction operator, which is written as >> which are two greater than signs as shown in the following example.

When the above code is compiled and executed, it will prompt you to enter a name. You enter a value and then hit enter to see the following result −

The C++ compiler also determines the data type of the entered value and selects the appropriate stream extraction operator to extract the value and store it in the given variables.

The stream extraction operator >> may be used more than once in a single statement. To request more than one datum you can use the following −

This will be equivalent to the following two statements −

The Standard Error Stream (cerr)

The predefined object cerr is an instance of ostream class. The cerr object is said to be attached to the standard error device, which is also a display screen but the object cerr is un-buffered and each stream insertion to cerr causes its output to appear immediately.

The cerr is also used in conjunction with the stream insertion operator as shown in the following example. Medieval total war 1 torrent pirate bay.

When the above code is compiled and executed, it produces the following result −

The Standard Log Stream (clog)

The predefined object clog is an instance of ostream class. The clog object is said to be attached to the standard error device, which is also a display screen but the object clog is buffered. This means that each insertion to clog could cause its output to be held in a buffer until the buffer is filled or until the buffer is flushed.

The clog is also used in conjunction with the stream insertion operator as shown in the following example.

When the above code is compiled and executed, it produces the following result −

You would not be able to see any difference in cout, cerr and clog with these small examples, but while writing and executing big programs the difference becomes obvious. So it is good practice to display error messages using cerr stream and while displaying other log messages then clog should be used.

Hey, I'm brand new to this site. Hopefully someone can help me out.

How do you clear the console screen without any system-compatibility issues?
This means that SYSTEM('CLS') and anything from a windows library (like #include) is not acceptable, as it will not run on linux/unix etc..
I know theres some tweaks you can do to linux which would make this work, but this is for a computer engineering course, and it has to run on everything.

I've created a function that looks something like this:

While this does pseudo-solve my problem, it leaves the text on the bottom of the console screen rather than the top, and you can just scroll up to see the previous output. It seems a little redundant to clear the screen in the console, but I need it for a lab at school. Although I don't think anyone else in my class has figuired out how yet..

Thanks.

How To Clear Output Screen In Turbo C++ 2

There is no way to do this without system dependencies. C++ doesn't know anything about the output device, so if you want to play with it you have to know something about it.

Start by altering reality such that standard C++ recognizes a 'screen' and a 'console' in a convenient way.

I'm impressed. Most programming courses actually take the opposite stance when it …

Start by altering reality such that standard C++ recognizes a 'screen' and a 'console' in a convenient way.

In other words, brute force. Outputting a bunch of newlines 'n' is the only portable way.

It is possible to write your C code to choose to compile specific options depending on what OS you are using, but that is a rather clunky option.

Another option is to write several separate cpp files that each define the same function, but implement it differently depending on the OS. Compile and link the one appropriate to the OS. (This is the most common option.)

For just playing with the console though, I recommend you to look at the curses library. There are several versions: curses, ncurses, and pdcurses. I recommend the latter. It is available on most POSIX capable systems, including windows.

If you want something really simple, and you have ANSI.SYS running on your Windows PC, you can just code: cout << '33[2J'; If it works it works. If not you'll just get some junk on the screen.

Sorry I couldn't be of more help.
