【三个数绝对值排序】2022-10-10

缘由绝对值比较，总是跑不过怎么办-编程语言-CSDN问答

template <class 形参>
inline void 算交换(形参& a, 形参& b){ 形参 ab = a - b;	a -= ab; b += ab; }
template <class 形参>
void 三个升序(形参& a, 形参& b, 形参& c)
{if (a > c)算交换(a, c);if (a > b)算交换(a, b);if (b > c)算交换(b, c);
}
void 三个数绝对值排序()
{//缘由int a = 0, b = 0, c = 0;cin >> a >> b >> c;if (a<0 && b<0 && c<0 || a>0 && b>0 && c>0){}else if (a<0 && b>0 && c>0){}else if (a>0 && b<0 && c>0){}else if (a>0 && b>0 && c<0){}else if (a<0 && b<0 && c>0){}else if (a>0 && b<0 && c<0){}
