The point is to read a file and then display the information from a 2D array. Then find the highest value in each column and divide all the numbers in each column by the high value for that column. Then display the quotients (which I put back into the original 2D array and then reprinted it). Its all straight out with no functions. But well separated with comments. I can't get the file to read. That is my first problem, so I can't even continue to debug the rest. If it helps the file data is this:

1.267 0.167 0.250 2.670 1.000

3.240 0.376 0.375 3.400 1.128

7.564 0.668 0.500 4.303 1.270

5.041 1.043 0.625 5.313 1.410

4.660 1.502 0.750 7.650 1.693

5.727 2.044 0.875 3.600 2.257
