Start by looking at your file... What do you see?

Ok first line is a single integer which happens to be 6

After that every line has how many numbers?

So the first line tells you what?

Can you figure out from the file how big your array needs to be?

Can you figure frome the file what kind of values it contains?

Can you figure out from the file how you might read in the values?

What choices do you have for storing this array?

Hint: Look for simple answers... this one isn't hard.
