Question

You may assume that a person eats at least once a day. That is, each row will have at least one number Example input file: Your program must read the input from a file named input2.txt 200 1000 450 845 1200 800 800 400 1500 1800 200 500 1000 700 1400 170 675 400 100 400 300 Use the concept of 2 dimensional Ragged Array to solve the second part of the assignment. In the second part, the client is only interested in the following information now the average number of calories consumed each day the average number of calories consumed in every meal of the week. For the example input file above the list of averages for Meals 1 to 5 is: 532.1428571, 1024.166667, 817.5, 466.6666667, and 300 . .
