Arrays and Vectors
Explore how to organize multiple data items using arrays and vectors in C++ by building a meal tracking app. Learn to store meal names and calories, calculate daily and weekly totals, and understand the flexibility of vectors versus fixed-size arrays. This lesson guides you through implementing dynamic data structures and applying them in real coding projects with AI assistance.
The project
You’ve decided to start eating healthier and want to track the meals you eat each day. Instead of typing one meal at a time and losing track, you want a system that can:
Store the meal names (Breakfast, Lunch, Dinner, Snacks).
Store the calories for each meal.
Calculate your daily total.
Add everything up for the week.
Typing just:
Breakfast: 400Lunch: 600
What you need is a list-like structure, a way to organize multiple values together so you can calculate and analyze them easily.
Your project: Build a healthy meals tracker that organizes meals by calories, shows your daily totals, and then adds them up for the week. ...
