Ternary conditional operator in C Sharp (C#) - Mini Project: Build & Apply

Using the Ternary Conditional Operator in C#

📖 Scenario: You are creating a simple program that decides if a person is an adult or a minor based on their age. This is like checking if someone can watch a movie with age restrictions.

🎯 Goal: Build a program that uses the ternary conditional operator to decide if a person is an adult or a minor and then prints the result.

📋 What You'll Learn

Create an integer variable called age with a specific value

Create a string variable called status that uses the ternary conditional operator

Use the ternary operator to set status to "Adult" if age is 18 or more, otherwise "Minor"

Print the status variable

💡 Why This Matters

🌍 Real World

Ternary operators are useful for quick decisions in programs, like checking user age for access or setting simple flags.

💼 Career

Understanding ternary operators helps write concise and readable code, a skill valued in software development jobs.

1

Create the age variable

Create an integer variable called age and set it to 20.

C Sharp (C#)

# Your code here

Need a hint?

Use int age = 20; to create the variable.

2

Prepare the status variable

Create a string variable called status but do not assign a value yet.

C Sharp (C#)

int age = 20;
// Your code here

Need a hint?

Declare string status; without assigning a value yet.

3

Use the ternary conditional operator

Assign status using the ternary conditional operator: if age is 18 or more, set status to "Adult", otherwise set it to "Minor".

C Sharp (C#)

int age = 20;
string status;
// Your code here

Need a hint?

Use status = age >= 18 ? "Adult" : "Minor"; to assign the value.

4

Print the status

Write a line to print the status variable using Console.WriteLine.

C Sharp (C#)

int age = 20;
string status;
status = age >= 18 ? "Adult" : "Minor";
// Your code here

Need a hint?

Use Console.WriteLine(status); to show the result.
