The following block of code works well accept for the fact that when it attempts to calculate the average temperature in a given amount of days, it does some math wrong. I put in a printf statement to isolate the problem and it seems to be adding wrong. Example; when I put in 6 -2 8 and -1, it adds them up and gets 13.50. I think its a casting problem but whenever I try to solve that I make it worse. How do I fix this?
