How do you use the clearscreen command in Microsoft visual c plus plus 6.0?

Answer 1

There is no such "command" in C++, let alone Visual C++. You are probably referring to the Turbo C++ clearscreen function. It is a 3rd party, user-defined function and is therefore not part of the C++ language itself.

You can roll your own clearscreen function, of course. The following is merely an example implementation, but note that this function is not cross-platform compatible because it employs platform-specific code.

You will also need platform-specific code to reposition the cursor after clearing the screen. As it stands, the cursor will be positioned 1000 characters from the top left of the console (immediately after the last insertion position).

#include<iostream>

#include<windows.h> // Non-cross platform, Windows only!

void ClearScreen( void )

{

HANDLE hConsoleOut;

CONSOLE_SCREEN_BUFFER_INFO csbiInfo;

DWORD dummy;

COORD home = { 0, 0 };

hConsoleOut = GetStdHandle( STD_OUTPUT_HANDLE );

GetConsoleScreenBufferInfo( hConsoleOut, &csbiInfo );

FillConsoleOutputCharacter( hConsoleOut, ' ', csbiInfo.dwSize.X * csbiInfo.dwSize.Y, home, &dummy );

}

int main()

{

// print some garbage:

int max=1000;

while(max--)

std::cout<<rand();

ClearScreen();

}
