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

Comparison operators

📖 Scenario: You are creating a simple program to compare ages of two friends to see who is older.

🎯 Goal: Build a program that stores two ages, compares them using comparison operators, and prints the results.

📋 What You'll Learn

Create two integer variables with exact ages

Create a boolean variable to store the comparison result

Use comparison operators to compare the ages

Print the comparison results exactly as specified

💡 Why This Matters

🌍 Real World

Comparing values is common in programs that make decisions, like checking user age for access or sorting data.

💼 Career

Understanding comparison operators is essential for writing conditions and logic in any software development job.

1

Create age variables

Create two integer variables called ageAlice and ageBob with values 25 and 30 respectively.

C Sharp (C#)

// Your code here

Need a hint?

Use int to declare the variables and assign the exact values.

2

Create comparison variables

Create two boolean variables called isAliceOlder and isBobOlder without assigning values yet.

C Sharp (C#)

int ageAlice = 25;
int ageBob = 30;
// Your code here

Need a hint?

Declare boolean variables using bool keyword.

3

Compare ages using comparison operators

Assign isAliceOlder to the result of ageAlice > ageBob and isBobOlder to the result of ageBob > ageAlice.

C Sharp (C#)

int ageAlice = 25;
int ageBob = 30;
bool isAliceOlder;
bool isBobOlder;
// Your code here

Need a hint?

Use the greater than operator > to compare the ages.

4

Print the comparison results

Print the values of isAliceOlder and isBobOlder using Console.WriteLine exactly as shown: "Is Alice older? {isAliceOlder}" and "Is Bob older? {isBobOlder}".

C Sharp (C#)

int ageAlice = 25;
int ageBob = 30;
bool isAliceOlder = ageAlice > ageBob;
bool isBobOlder = ageBob > ageAlice;
// Your code here

Need a hint?

Use Console.WriteLine with string interpolation $"...{variable}..." to print the results.
