Answer 1

clrscr() is old stuff used in DOS. clrscr is not in conio.h anymore, atleast in VC2008/2010 if I remember correctly.

cin / cout are C++ stuff.  Both are in the namespace std.

 Her is an example on how to use cin / cout:

Answer 2

clrscr() was never in VC++, it is a function from the old
Borland - and now Embarcadero - compilers. It was/is usable
in both DOS and Win32 console programs built with those
compilers.

In Visual studio, I think you can use:

#include <stdlib.h>

void main()

{

system("cls");

.....

}

------

clrscr() instead of system("cls"),

and system("cls") into stdlib.h
