Memory

Introduction

At one point or another, we came across variables. They’re our go-to tool for:

• Storing and processing information
• Doing calculations and producing an output

To illustrate this, consider a scenario where we want to read the first name, age, and email address of a user, each separated with a space in a single line. Our code will display the entered data and store it in a file (user_data.txt) for later use.

Don’t worry if you’re not familiar with working with files in C! It is just an example for us to analyze.
