Assignment #2 Solution



Objective: The goal of this assignment is to practice 2-dimensional ragged arrays.

Background: Within a healthy, balanced diet, a grownup needs 2,250 calories a day. You will write a program to track calorie intake of a person.

Assignment: Calorie intake data from a person is provided in a text file named input.txt. There are arbitrary number of double values on each line, separated by spaces. The numbers represent the number of calories consumed for meals and/or snacks on a day. The file includes data for exactly one week starting from Monday. That is, the file contains seven lines of text. The topmost line is for Monday and the line at the bottom is for Sunday. Your program should read the data from the file into a 2- dimensional array. The number of rows of the 2-dimensional array must be equal to the number of valid lines in the file. The numbers in the i-th row of the 2-dimensional array must appear in the same sequence of numbers in the i-th row of the file. After reading the input file into the 2-dimensional array, report the following items.

a list of total calories consumed each day

a list of days when more calories than required are consumed

average calories consumed during the i-th meal/snack (average over all seven days)

You must write a method with exactly one 2-dimensional array parameter to compute each of the listed items above and display the result.

Example input file:

800 1000 100

450 100 845 20 1200 200

1800 250 400

0 1500 800 120

600 500

700 1400 1700 100


You should print an error message and terminate if there are not exactly 7 lines.

Deliverables: The name of your source file must be It must be submitted via Blackboard. Your TAs will let you know about any other requirements.
