Why loop control is required - See It in Action

Why Loop Control is Required in C

📖 Scenario: Imagine you are organizing a small event and need to count the number of guests entering. You want to stop counting once a certain number is reached to avoid overcrowding.

🎯 Goal: You will write a simple C program that uses loop control to count guests until a maximum limit is reached, demonstrating why controlling loops is important.

📋 What You'll Learn

Create an integer variable called guest_count initialized to 0

Create an integer variable called max_guests and set it to 5

Use a while loop that runs as long as guest_count is less than max_guests

Inside the loop, increment guest_count by 1

Print the current guest_count inside the loop

After the loop, print a message saying "Maximum guests reached"

💡 Why This Matters

🌍 Real World

Counting guests or items and stopping at a limit is common in event management, inventory control, and many other real-life tasks.

💼 Career

Understanding loop control is essential for writing efficient and safe programs that do not run endlessly and handle tasks correctly.

1

Create guest count variables

Create an integer variable called guest_count and set it to 0. Also create an integer variable called max_guests and set it to 5.

C

// Your code here

Need a hint?

Use int guest_count = 0; and int max_guests = 5; inside main().

2

Set up the while loop

Add a while loop that runs as long as guest_count is less than max_guests.

C

#include 

int main() {
    int guest_count = 0;
    int max_guests = 5;

    // Add while loop here

    return 0;
}

Need a hint?

Use while (guest_count < max_guests) to start the loop.

3

Increment guest count and print inside loop

Inside the while loop, increment guest_count by 1 and print the current guest_count using printf.

C

#include 

int main() {
    int guest_count = 0;
    int max_guests = 5;

    while (guest_count < max_guests) {
        // Increment guest_count and print it
    }

    return 0;
}

Need a hint?

Use guest_count++; to add one and printf("Guest count: %d\n", guest_count); to print.

4

Print message after loop ends

After the while loop, print the message "Maximum guests reached" using printf.

C

#include 

int main() {
    int guest_count = 0;
    int max_guests = 5;

    while (guest_count < max_guests) {
        guest_count++;
        printf("Guest count: %d\n", guest_count);
    }

    // Print message after loop

    return 0;
}

Need a hint?

Use printf("Maximum guests reached\n"); after the loop.
