clrscr is one of the easier option.

That will NOT work for compilers which conform to ANSI C, 'cuz the clrscr() is no more present.

So, you can use system("CLS"); to clear screen, but that's OS specific.
So it's better to write a user-defined func like :

void ClearScreen(void)
{
      HANDLE hStdout = GetStdHandle(STD_OUTPUT_HANDLE);
      CONSOLE_SCREEN_BUFFER_INFO csbi;
      GetConsoleScreenBufferInfo(hStdout,&csbi);
      const COORD startCoords = {0,0};
      DWORD dummy;

      FillConsoleOutputCharacter(hStdout,' ',csbi.dwSize.X * csbi.dwSize.Y,startCoords,&dummy);
      SetConsoleCursorPosition(hStdout, startCoords);
}

Remember to #include <windows.h>.

excuse me but it's not working and has a error like this:
error C2601: 'ClearScreen' : local function definitions are illegal

It compiles perfectly fine on my machine.

Error C260 indicates that you are trying to declare a function inside a function.
So, did you directly paste the above code inside your main() ???

You should not do that. You should paste the above function globally and call it from main() or wherever wherever required, this way : ClearScreen();
