Enum declaration - Mini Project: Build & Apply

Enum declaration

📖 Scenario: You are creating a simple program to represent days of the week using an enum. This helps you use meaningful names instead of numbers in your code.

🎯 Goal: Learn how to declare an enum in C to represent the days of the week and print one of the days.

📋 What You'll Learn

Declare an enum named Day with the days: Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday.

Create a variable of type Day and assign it the value Wednesday.

Print the integer value of the Day variable.

💡 Why This Matters

🌍 Real World

Enums help represent fixed sets of related values like days, colors, or states in a readable way.

💼 Career

Understanding enums is important for writing clear and maintainable code in C programming jobs.

1

Declare the enum Day

Declare an enum named Day with these exact members in order: Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday.

C

// Declare enum Day with Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday
// Your code here

Need a hint?

Use the syntax enum Name { item1, item2, ... }; to declare an enum.

2

Create a variable of type Day

Create a variable named today of type Day and assign it the value Wednesday.

C

enum Day { Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday };
// Create variable today of type Day and assign Wednesday
// Your code here

Need a hint?

Use enum Day variableName = Value; to create and assign an enum variable.

3

Print the integer value of today

Write a printf statement to print the integer value of the variable today.

C

enum Day { Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday };
enum Day today = Wednesday;
// Print the integer value of today
// Your code here

Need a hint?

Use printf("%d\n", variable); to print an integer value.

4

Run the program to see the output

Run the program and observe the output. It should print the integer value corresponding to Wednesday.

C

#include 

enum Day { Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday };

int main() {
    enum Day today = Wednesday;
    printf("%d\n", today);
    return 0;
}
// Run the program

Need a hint?

The output should be 3 because Sunday starts at 0 and Wednesday is the fourth item.
