Solution 2

C++

if (bomy > 46){
  gotoxy(playerx, 47);
  printf("Kaboom!");
  delay(40);
  gotoxy(playerx, 47);
  printf("       ");
}

Solution 1

We can't say: it's going to depend on the system you are using. There is nothing "built in" to printf or general purpose C libraries which allow you to clear text you have printed (because the general purpose stuff comes from the days of paper rolls, raster and vector VDUs, etc., and there was no "one way" to do it on every device).

Check your system libraries for an appropriate "clear screen" or similar function.

well printf is an build in function do you need m includes to tell me how or not.
i have found a different C++ file with different function. one of these functions contains clrscr(); (clearscreen) but if i use that in the IF function even my plane will disapear, do you have a different C++ file with a function that can delete text? and not the whole screen (sorry im a beginner ^^)

If you are doing this on the entire screen of the terminal, then you require to remove everything from the screen and re-print everything based on the logic and state of the program.
