1.在高德地图上绘制的多边形:经纬度逗号分隔格式:上面是用来方便存坐标的对象:下面是方法测试:直接复制代码即可运行 public class Point { private Double x; private Double y; public Point (Double x , Double y) { this.x = x; this.y = y; } public Double getX() { return x; } public void setX(Double x) { this.x =

/*函数的输入:(1)当前点的坐标p(2)区域顶点数组pt[]:(3)顶点数nCount 输出: 在区域内返回TRUE,否则返回FALSE. Point类型是一个结构: struct Point { 类型 x;//此处类型根据采用的经纬度类型决定. 类型 y; };*/BOOL PtInPolygon(Point p, Point pt[], int nCount){ int nCross = 0; for (int i = 0; i < nCount; i++) {
python中判断某一个元素是否在一个列表中,可以使用关键字in 和 not in. 示例如下: 如果需要输出相应的信息,可以搭配使用if语句,这里不赘述. ------------------------------------------------------------------------------------------分割线------------------------------------------------------------------------------
