Hey guys how do you clear the screen in the windows console?? I thought it was

system("clear");

and it doesn't seem to work... Thanks!

Using system() is not a great idea nor a good programming habit. Therefore I suggest you give this a look as a alternate to of system():

A Proof-Of-Concept code demonstrating a alternate to system():

#include<Windows.h>
#include<iostream>

void ClearScreen(void)
  {
  HANDLE                     hStdOut;
  CONSOLE_SCREEN_BUFFER_INFO csbi;
  DWORD                      count;
  DWORD                      cellCount;
  COORD                      homeCoords = { 0, 0 };

  hStdOut = GetStdHandle( STD_OUTPUT_HANDLE );
  if (hStdOut == INVALID_HANDLE_VALUE) return;

  /* Get the number of cells in the current buffer */
  if (!GetConsoleScreenBufferInfo( hStdOut, &csbi )) return;
  cellCount = csbi.dwSize.X *csbi.dwSize.Y;

  /* Fill the entire buffer with spaces */
  if (!FillConsoleOutputCharacter(
    hStdOut,
    (TCHAR) ' ',
    cellCount,
    homeCoords,
    &count
    )) return;

  /* Fill the entire buffer with the current colors and attributes */
  if (!FillConsoleOutputAttribute(
    hStdOut,
    csbi.wAttributes,
    cellCount,
    homeCoords,
    &count
    )) return;

  /* Move the cursor home */
  SetConsoleCursorPosition( hStdOut, homeCoords );
  }

int main()
{
	std::cout<<"Hello World!\n Now can you clear me up? Press [ENTER] to continue";
	std::cin.get();
	ClearScreen();
	/*
	   Insert a break here to see that the screen is successfully cleared. 
	*/
}

Oh, I'm sorry I didn't mean to lead them in the wrong way.

I had been doing this myself and didn't know there was anything wrong with it.

Thanks for the input, it's just that I'm not quite into windows.h ... could you tell me why

system("(...)");

is not recommended?
