A shorter way to write following c++ code (if-else)

I need to know is there a better / shorter way to write following code in c++. (while going through the main if-else (step by step), additional check for variable 'y' will be added)

int x = 5, y = 4;

if(x == 1){
  if(y == 1)
      printf("ok");
  else
      printf("not ok");
}
else if(x == 2){
  if((y == 1) || (y == 2))
      printf("ok");
  else
      printf("not ok");
}
else{
  if((y == 1) || (y == 2) || (y == 3))
      printf("ok");
  else
      printf("not ok");
}
