Question

float [] pt1x = {0.580f, 0.680f, 0.780f}; 
float [] pt1y = {1.128f, 1.228f, 1.328f}; 

foreach (float xpt in pt1x) {
   System.Console.WriteLine("xpt = " + xpt);
       foreach (float ypt in pt1y) {
        System.Console.WriteLine("ypt = " + ypt);
      }  
}

------my output:
xpt = 0.58
ypt = 1.128
ypt = 1.228
ypt = 1.328
xpt = 0.68
ypt = 1.128
ypt = 1.228
ypt = 1.328
xpt = 0.78
ypt = 1.128
ypt = 1.228
ypt = 1.328
---------------here is what I NEED

 to get below:
xpt = 0.58
ypt = 1.128
xpt = 0.68
ypt = 1.228
xpt = 0.78
ypt = 1.328

Answer 1

float [] pt1x = {0.580f, 0.680f, 0.780f};  
float [] pt1y = {1.128f, 1.228f, 1.328f};  

    for (int i=0; i < pt1x.Length; i++)
    {
        Console.Writeline("xpt = " + pt1x[i]);
        Console.Writeline("ypt = " + pt1y[i]);
    }
