Thread: array size [10] need help!! any experts

Hi Guys,

my choice 1. i key in the calories for the day but my program can calculate up till 4 days when i exit. so i am asking how to use array to calculate up to 10 days when i press 3 exit.

an example of my output // display

1. Enter Food and Intake per day
2. Display food intake status
3. Exit

so let say i key in 8 days in 1. Enter Food and Intake per day , my exit 3. should show 8 days of the calculated intake by using array

heres the code thanks alot
