Improving code readability - Mini Project: Build & Apply

Improving code readability

📖 Scenario: You are working on a simple program that calculates the area of rectangles. The original code is hard to read because it uses unclear variable names and lacks spacing.

🎯 Goal: You will improve the code readability by using clear variable names, adding spacing, and organizing the code neatly. This will make the program easier to understand and maintain.

📋 What You'll Learn

Create variables with clear and descriptive names

Use proper spacing around operators

Calculate the area by multiplying width and height

Print the results clearly

💡 Why This Matters

🌍 Real World

Clear and readable code is important in real projects so that teammates and future you can easily understand what the program does.

💼 Career

Employers value programmers who write clean, readable code because it reduces bugs and makes collaboration easier.

1

Create variables for rectangle dimensions

Create two integer variables called width and height and set them to 5 and 10 respectively.

C

// Create two integer variables called width and height and set them to 5 and 10 respectively
// Your code here

Need a hint?

Use int width = 5; and int height = 10; to create the variables.

2

Add a variable for area calculation

Add an integer variable called area and initialize it to 0.

C

#include 

int main() {
    int width = 5;
    int height = 10;
    // Add an integer variable called area and initialize it to 0
    // Your code here
    return 0;
}

Need a hint?

Use int area = 0; to create the area variable.

3

Calculate the area using clear expressions

Calculate the area by multiplying width and height and store the result in area. Use spaces around the multiplication operator.

C

#include 

int main() {
    int width = 5;
    int height = 10;
    int area = 0;
    // Calculate the area by multiplying width and height
    // Your code here
    return 0;
}

Need a hint?

Write area = width * height; with spaces around the *.

4

Print the area with a clear message

Print the text "Area of rectangle: " followed by the value of area using printf. Use a newline at the end.

C

#include 

int main() {
    int width = 5;
    int height = 10;
    int area = 0;
    area = width * height;
    // Print the area with a clear message
    // Your code here
    return 0;
}

Need a hint?

Use printf("Area of rectangle: %d\n", area); to print the result.
