I have come to a blank on how to do this. I have to calculate how many days there are between a range of years. I have declared everything and I have gave it the rules to how many days there are in a year due to leap years and nonleapyears. I know I need to create a loop that will add all those days but I dont know where to start at for this loop. Do i use a for loo or a while loop. If I use one of these loops what would be the structure. I am not asking for the code by anymeans because i want to figure that out myself I just need to get my wheels spinning and am at a blank right now. Tahnks for any help.
