Hi All,
Hopefully this is the correct location to post this. I am trying to read the second, third and fourth column of the data file in excel and determine the min and max of each column. I keep getting 0 as a value, due to the fact when there is no data in the array it is reading as 0, any help on how to either program that zero is not an acceptable answer or how to make it stop reading after there is no more data would be helpful. I am new at this so any explanation would be great, I attached the data file and my program thus far.
