If-else execution flow in C Sharp (C#) - Mini Project: Build & Apply

If-else execution flow

📖 Scenario: You are creating a simple program to check if a person is old enough to vote. Voting age is 18 years or older.

🎯 Goal: Build a program that uses if-else statements to decide if a person can vote based on their age.

📋 What You'll Learn

Create an integer variable called age with the value 20

Create an integer variable called votingAge with the value 18

Use an if-else statement to check if age is greater than or equal to votingAge

Print "You can vote!" if the condition is true

Print "You cannot vote yet." if the condition is false

💡 Why This Matters

🌍 Real World

Many applications need to make decisions based on user input or data, like checking age for voting or access permissions.

💼 Career

Understanding if-else statements is fundamental for programming jobs, as they control how programs respond to different situations.

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 to declare the variable and assign the value 20.

2

Create the votingAge variable

Create an integer variable called votingAge and set it to 18.

C Sharp (C#)

int age = 20;
// Your code here

Need a hint?

Declare votingAge as an integer and assign 18.

3

Write the if-else statement

Write an if-else statement that checks if age is greater than or equal to votingAge. Use age >= votingAge as the condition.

C Sharp (C#)

int age = 20;
int votingAge = 18;
// Your if-else statement here

Need a hint?

Use if (age >= votingAge) and else blocks with Console.WriteLine inside.

4

Print the result

Run the program and print the output to show if the person can vote or not.

C Sharp (C#)

int age = 20;
int votingAge = 18;
if (age >= votingAge)
{
    Console.WriteLine("You can vote!");
}
else
{
    Console.WriteLine("You cannot vote yet.");
}
// Print the output

Need a hint?

The program should print exactly You can vote! because age is 20.
