Logical operators in C Sharp (C#) - Mini Project: Build & Apply

Logical Operators in C#

📖 Scenario: You are building a simple access control system for a club. The club has rules about who can enter based on age and membership status.

🎯 Goal: Create a program that uses logical operators to decide if a person can enter the club.

📋 What You'll Learn

Create variables to store age and membership status

Create a variable for minimum age allowed

Use logical operators to check if the person is old enough and a member

Print whether the person can enter or not

💡 Why This Matters

🌍 Real World

Access control systems often check multiple conditions like age and membership before allowing entry.

💼 Career

Understanding logical operators is essential for making decisions in software, such as validating user input or controlling program flow.

1

Create variables for age and membership status

Create an integer variable called age and set it to 20. Create a boolean variable called isMember and set it to true.

C Sharp (C#)

// Your code here

Need a hint?

Use int for numbers and bool for true/false values.

2

Create a minimum age variable

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

C Sharp (C#)

int age = 20;
bool isMember = true;
// Your code here

Need a hint?

This variable will hold the minimum age allowed to enter.

3

Use logical operators to check entry conditions

Create a boolean variable called canEnter that is true only if age is greater than or equal to minAge and isMember is true. Use the && operator.

C Sharp (C#)

int age = 20;
bool isMember = true;
int minAge = 18;
// Your code here

Need a hint?

Use parentheses to group conditions clearly.

4

Print the result

Write a Console.WriteLine statement that prints "Access granted" if canEnter is true, otherwise prints "Access denied". Use the ternary operator.

C Sharp (C#)

int age = 20;
bool isMember = true;
int minAge = 18;
bool canEnter = (age >= minAge) && isMember;
// Your code here

Need a hint?

The ternary operator looks like: condition ? valueIfTrue : valueIfFalse.
