Use a map to create a table of foods and calories per portion. for example carrots-45, ice cream-250, and so on. place at least 10 foods in your map. use a random number generator to pick 4 foods per meal. print out the meal and its calorie total.

 

Use Map to create a table containing food and its corresponding calories, such as carrot-45, ice cream-250, and so on. Map contains at least 10 types of food, 4 types of food are randomly selected for each meal, and the selected food and its calories are printed.
