秘密行动组第一季剧情:implicit declaration of function `int hypot(...)\'

来源：百度文库编辑：查人人中国名人网时间：2024/05/20 00:31:56

double radius; center_x,center_y,current_x,current_y都是double类型的
出错的为下面这条语句：
radius SET_TO hypot((center_x - current_x),(center_y - current_y));

implicit declaration of function `int hypot(...)' 这句是什么意思了，如何解决？
