Logical operators - Mini Project: Build & Apply

Logical Operators in C

📖 Scenario: You are creating a simple program to check if a person is eligible for a special discount based on their age and membership status.

🎯 Goal: Build a C program that uses logical operators to decide if a person qualifies for the discount.

📋 What You'll Learn

Create variables with exact names and values as instructed

Use the logical AND && operator

Print the exact output as specified

💡 Why This Matters

🌍 Real World

Logical operators are used in programs to make decisions, like checking if someone qualifies for discounts or access.

💼 Career

Understanding logical operators is essential for writing conditions in software development, quality assurance, and data validation.

1

Create variables for age and membership status

Create an integer variable called age and set it to 25. Create an integer variable called is_member and set it to 1 (1 means true, 0 means false).

C

# Create an integer variable called age and set it to 25
# Create an integer variable called is_member and set it to 1

Need a hint?

Use int to declare variables and assign the values exactly as given.

2

Create a variable for minimum age

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

C

int age = 25;
int is_member = 1;
# Create an integer variable called min_age and set it to 18

Need a hint?

This variable will be used to check if the person is old enough for the discount.

3

Use logical operators to check eligibility

Create an integer variable called eligible and set it to the result of the expression: (age >= min_age) && (is_member == 1).

C

int age = 25;
int is_member = 1;
int min_age = 18;
# Create an integer variable called eligible and set it to (age >= min_age) && (is_member == 1)

Need a hint?

Use the logical AND operator && to combine the two conditions.

4

Print the eligibility result

Write a printf statement to print "Eligible: 1" if the person is eligible, or "Eligible: 0" if not, by printing the value of eligible.

C

int age = 25;
int is_member = 1;
int min_age = 18;
int eligible = (age >= min_age) && (is_member == 1);
# Print the eligibility result using printf

Need a hint?

Use printf("Eligible: %d\n", eligible); to print the result.
