Logical operators in C++ - Mini Project: Build & Apply

Logical Operators Practice

📖 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 program that uses logical operators to decide if a person qualifies for the discount.

📋 What You'll Learn

Create variables for age and membership status

Create a variable for minimum age to qualify

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

Print the eligibility result

💡 Why This Matters

🌍 Real World

Checking eligibility for discounts or offers based on multiple conditions is common in stores, websites, and apps.

💼 Career

Understanding logical operators is essential for writing conditions in programming, which is a key skill for any software developer.

1

Create variables for age and membership status

Create an int variable called age and set it to 25. Create a bool variable called isMember and set it to true.

C++

// Your code here

Need a hint?

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

2

Create a variable for minimum age to qualify

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

C++

int age = 25;
bool isMember = true;
// Your code here

Need a hint?

This variable will hold the minimum age required for the discount.

3

Use logical operators to check eligibility

Create a bool variable called isEligible that is true only if age is greater than or equal to minAge and isMember is true. Use the logical AND operator &&.

C++

int age = 25;
bool isMember = true;
int minAge = 18;
// Your code here

Need a hint?

Use parentheses to group conditions clearly.

4

Print the eligibility result

Use std::cout to print "Eligible for discount: " followed by the value of isEligible. Include #include <iostream> and use std::boolalpha to print true or false instead of 1 or 0.

C++

#include 

int main() {
int age = 25;
bool isMember = true;
int minAge = 18;
bool isEligible = (age >= minAge) && isMember;
// Your code here
return 0;
}

Need a hint?

Remember to include #include <iostream> and use std::boolalpha to print true or false.
