Aug 04, 2008 I highly recommend you don't stick to this method. You can simply do: cout string(50, 'n'); to print lines to seem like the terminal was 'cleared'. The reason is that the system function calls system-specific functions, which makes your program less portable. I'm too tired to explain. Using the Clear method is equivalent invoking the MS-DOS cls command in the command prompt window. When the Clear method is called, the cursor automatically scrolls to the top-left corner of the window and the contents of the screen buffer are set to blanks using the. Clrscr in C Function 'clrscr' (works in Turbo C compiler only) clears the screen and moves the cursor to the upper left-hand corner of the screen. If you are using the GCC compiler, use system function to execute the clear/cls command. Clear Output Screen - When we run a program, previous output or other command prompt/ Linux Terminal command's output appear there. We can clear the output screen using C program. Functions which are used to clear output screen depend on the compiler, commonly used functions/methods are: Using clrscr - For TurboC Compiler.

Assuming the terminfo call was successful, and the terminal type is a smart (not 'dumb' or 'tty') then you might as well use a terminfo (or termcap) clear screen instruction (clear / cl), rather than pushing multiple newlines, which can be slow on larger X-Window terminals, particularly across networks.

I m also having trouble that when i make wrong ccalculation suchs as 5+5+, the program is looping the 5 + 5 calculation and ignores any input.

To clear your screen you can use system('CLS') - keep in mind this makes your program less portable though.
The reason you continuously loop when you enter bad input is because you're trying to accept a number, but are receiving a char, and your input buffer is overflowing.
Try '>flushing the input stream after you get the data you want.
Also, I would recommend using a switch rather than multiple IFs.

-->Definition
Clears the console buffer and corresponding console window of display information.
Exceptions
An I/O error occurred.
Examples
The following example uses the Clear method to clear the console before it executes a loop, prompts the user to select a foreground and background color and to enter a string to display. If the user chooses not to exit the program, the console's original foreground and background colors are restored and the Clear method is called again before re-executing the loop.
The example relies on a
GetKeyPress
method to validate the user's selection of a foreground and background color.This example demonstrates the CursorLeft and CursorTop properties, and the SetCursorPosition and Clear methods. The example positions the cursor, which determines where the next write will occur, to draw a 5 character by 5 character rectangle using a combination of '+', '|', and '-' strings. Note that the rectangle could be drawn with fewer steps using a combination of other strings.

Note
Attempting to call the Clear method when a console application's output is redirected to a file throws a IOException. To prevent this, always wrap a call to the Clear method in a

block.
