In this C++ lesson, you’ll learn Arrays in the simplest way: instead of creating many variables, you store multiple values inside ONE array and access them using indexes [].
You'll learn:
What an array is (a group of values of the same type).
How to declare an array: int x[5];
How to initialize an array using { }.
How to access elements with indexing: x[0], x[1], x[2]... (index starts at 0).
Quick reminder: you can access characters using [] (string/char examples).
Homework (with solution idea):
Create a float array for 3 student grades:
Ask the user to enter grade 1, 2, 3 into grades[0], grades[1], grades[2]
Calculate the average: avg = (grades[0] + grades[1] + grades[2]) / 3
Print the average
