Arrays and Vectors
Learn C++ arrays and vectors by building a healthy meals tracker that stores daily calories and helps you see weekly totals.
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.
The programming concept
The programming concept for today is arrays and vectors. Think of an array like a shopping basket: instead of holding just one item, you can place many items inside and carry them together. In C++, arrays and vectors can store numbers, text, or even more complex data types.
