找到直线中点的程序-yiteyi-C++库

给定直线的两个坐标，起点为（x1，y1），终点为（x2，y2），找出直线的中点。 例如：

null

Input  : x1 = –1, y1 = 2,          x2 = 3, y2 = –6Output : 1,–2Input  : x1 = 6.4, y1 = 3          x2 = –10.7, y2 = 4Output : –2.15, 3.5

推荐：请尝试你的方法 {IDE} 首先，在进入解决方案之前。

中点公式： 两点（x1，y2）和（x2，y2）的中点是通过以下公式找到的点M： M=（（x） _1. +x _2. )/2、（y） _1. +y _2. )/2)
