§ clear()

template<class Char >
static bool xtd::basic_console< Char >::clear ( )
inlinestaticnoexcept

Clears the console buffer and corresponding console window of display information.

Remarks
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.
Example
The following example uses the cear 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 get_key_press method to validate the user's selection of a foreground and background color.
Example
This example demonstrates the cursor_left and cursor_top properties, and the set_cursor_position 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.
