Hey Guys, really confused by this code I've written and why it's throwing an error. Essentially I have some arrays of length (5) and I'm trying to do some calculations with them and store those in an array of length 10. So the code is designed to do ten calculations with five number arrays, so naturally I designed it to have two different counters within the for loop. The first one should reset when it reaches 5, and the other one kills the loop when it hits 10. What doesn't make any sense at all is that the program is spitting out the output that i=5, but it's not going into the if statement and reseting itself so I get thrown an error about my array being out of bounds.
Thanks for any help
