小冰冰传奇100级阵容:implicit declaration of function `int hypot(...)\'

来源：百度文库编辑：高考问答时间：2024/07/08 15:21:38

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？
？？

implicit declaration of function `int hypot(...)\' 什么是implicit returns? implicit function 指什么？ Declaration syntax error declaration syntax error C语言declaration syntax error fatal error creating basic vertex declaration failed Declaration syntax error in function main 标书中Bid-Securing Declaration 翻译,及 too many types in declaration怎么解决
