Introduction to Arrays

• Lesson 45: Introduction to Arrays (Date: December 06, 2024)

Storing Multiple Values

• Objective: Learn how to efficiently store multiple values, particularly grades.

• Example of inefficient storage:

  • int grade1;

  • int grade2;

  • int grade3;

  • int grade4;

  • int grade5;

  • int grade6;

  • int grade7;

  • int grade8;

  • int grade9;

  • int grade10;

• Problem with this method:

  • Inefficient: Manually declaring each variable takes up more space and is not scalable.

  • This method does not facilitate easier management of data.

Solution: Arrays

• Arrays provide a scalable and efficient way to store multiple values of the same type in a single collection.

• Allows the storage of 10 (or more) grades in a more manageable format.
