Which input are you trying to validate? If it's the number for snacks, you already have the basic structure in place, but you treat all numbers higher than 5 as if it's a 7. It looks like a mistake that a value of 5 results in incrementing snacks_group_6. Nothing increments snacks_group_5 and there is no check for a snack value of 6. To properly check for values higher than 7, you should also have a specific check for 6 and 7, and use the else to catch the invalid values.

Thanks for the help, I corrected what you told me and I used a do-while loop which help me figure it out
