c - 三元运算符“如果”声明

嘿，伙计们，我想知道有没有一种不使用三元运算符的方法来写这个，通过使用if语句，这里是im在times运算符上难倒的代码：

 int x1 = place.getX();
 int x2 = x1 +
   ((direction == direction.NORTH || direction == direction.SOUTH ? shipLength : shipWidth) - 1) *
   (direction == direction.NORTH || direction == direction.EAST ? -1 : 1);
 int y1 = place.getY();
 int y2 = y1 +
   ((direction == direction.NORTH || direction == direction.SOUTH ? shipWidth : shipLength) - 1) *
   (direction == direction.WEST || direction == direction.NORTH ? -1 : 1);

最佳答案

一个更少的斯帕盖蒂版本：

int x1 = place.getX();
int y1 = place.getY();
int x2, y2;
switch(direction) {
case NORTH:
  x2 = x1-(shipLength-1);
  y2 = y1-(shipWidth-1);
  break;
case SOUTH:
  x2 = x1+(shipLength-1);
  y2 = y1+(shipWidth-1);
  break;
case EAST:
  x2 = x1-(shipWidth-1);
  y2 = y1+(shipLength-1);
  break;
case WEST:
  x2 = x1+(shipWidth-1);
  y2 = y1-(shipLength-1);
  break;
default:
  x2 = x1+(shipWidth-1);
  y2 = y1+(shipLength-1);
  //printf("Your ship seems to be sinking!\n");
  //exit(1);
}

如果您特别想要if-else if版本，那么将上面的内容转换为该版本应该很简单。
