在C中編寫距離和角度＃

Question

我正在C＃中處理我的第一個程序，並且在計算距離和角度時出現問題。我的目的是提示X1，Y1值，X2，Y2值，並計算兩點之間的距離和角度。我將在下面粘貼我的（非常可怕的）代碼。預先感謝任何幫助！

 //prompt and store the x and y for two points 
     Console.WriteLine("Please enter X1:"); 
     float point1X = float.Parse(Console.ReadLine()); 
     Console.WriteLine("Please enter Y1:"); 
     float point1Y = float.Parse(Console.ReadLine()); 
     Console.WriteLine("Please enter X2:"); 
     float point2X = float.Parse(Console.ReadLine()); 
     Console.WriteLine("Please enter Y2:"); 
     float point2Y = float.Parse(Console.ReadLine()); 
     Console.WriteLine(""); 

     //calculate the distance 
     double deltaX= Math.Pow(point2X - point1X, 2); 
     double deltaY= Math.Pow(point2Y - point1Y, 2); 
     Console.WriteLine("double deltaX, double deltaY"); 
     Console.WriteLine(""); 

     //calculate the angle 
     double angle = Math.Atan2(deltaX, deltaY); 
     Console.WriteLine("double angle"); 
     Console.WriteLine(""); 

Answer 1

如果這是這樣的，你搜索，這是數學，而不是C＃;-)：

 //calculate the distance 
     ... 
     Console.WriteLine("Distance : " + Math.Sqrt(deltaX + deltaY)); 

     //calculate the angle 
     double angle = Math.Atan2(point2Y - point1Y, point2X - point1X); 
     ... 
     Console.WriteLine(angle + " Rad"); 
     Console.WriteLine(angle * 180/Math.PI + " Deg");
