ClearScreen

If most people #include <conio.h> for clrscr() function, how come my conio.h doesn't seem to have it. Does clrscr not appear in VC++ conio?

Nope, you have to fake it.

or use system("cls") that I think is in windows.h, it might be in conio.h

[EDIT]
Or maybe its in iostream.

system is in cstdlib and stdlib.h as it's a standard function in both C and C++.

Or you could just write your own clear screen function ;)

Code:

---

//Basic Functions..
//basicf.h
#ifndef _BASICF_H_
#define _BASICF_H_

#include<windows.h>

void clrscr()
{
        HANDLE hOutput = GetStdHandle(STD_OUTPUT_HANDLE);
        COORD cScreenStart={0,0};
        DWORD dwScreenSize;
        DWORD dwCharsWritten;
        CONSOLE_SCREEN_BUFFER_INFO cWindowInfo;

        GetConsoleScreenBufferInfo(hOutput,&cWindowInfo);

        dwScreenSize = cWindowInfo.dwSize.X * cWindowInfo.dwSize.Y;

        FillConsoleOutputCharacter(hOutput,TEXT(' '),dwScreenSize,cScreenStart,&dwCharsWritten);

        GetConsoleScreenBufferInfo(hOutput,&cWindowInfo);

        FillConsoleOutputCharacter(hOutput,TEXT(' '),dwScreenSize,cScreenStart,&dwCharsWritten);

        SetConsoleCursorPosition(hOutput,cScreenStart);
}

#endif // _BASICF_H_

Just include it as a header file...and well then youve got your very own clear screen function ;)
