Is this a scope issue?

ive got my program working, not exactly how I want it to, but it works. for my final assignment, I have to read from a file and write the info to a structure. I figured I would write the data to arrays (for the different value types) and then build the structure from the arrays. I am having an issue with making sure that the array is built properly. As you will notice, I have added a cout at the end of main to test for values in the array. Why is it that I cant cout the proper values from the array at the end of main? It prints out the proper values during the loop so I'm guessing its the placement of my last cout statement but I cant quite nail it down. I have tried adding it to everywhere I can think of but still not working. Is there a different way to test the values of the array? Am I just doing it all wrong?

This is what my text file looks:

4 95 96 97 98 0.20
3 100 100 100 0.10

Is there anybody that can help me with this?
