Clear Screen In C++ Dev
Sep 24, 2011 Clear screen in dev c. C / C Forums on Bytes. How do i clear the screen using dev c. Is there a built in function, if so, what header function should i use. Please note, thi is dev c. In the program, we display the message (Press any key to clear the screen) using printf and ask the user to press a key. When the user presses a key screen will be cleared and another message will be printed. Function clrscr doesn't work in Dev C compiler. Coming mainly from a C background, the requirement to use the struct keyword in C when declaring a stack variable or function parameter seems unnecessary, somewhat uglies up the code and reduces portability between C and C (which I recognize is not the responsibility of the C standard, but still).
-->Clear Screen In C++ Device
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.

Remarks
How To Clear Screen In C
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 current foreground background colors.
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 try…catch block.
