Break statement in C++ - Mini Project: Build & Apply

Using the Break Statement in C++

📖 Scenario: You are creating a simple program that checks a list of numbers to find the first number that is greater than a certain limit. Once the program finds this number, it should stop checking the rest.

🎯 Goal: Build a C++ program that uses a break statement inside a for loop to stop the loop when a number greater than a limit is found.

📋 What You'll Learn

Create an array of integers with exact values

Create an integer variable for the limit

Use a for loop to check each number in the array

Use a break statement to stop the loop when a number greater than the limit is found

Print the first number found that is greater than the limit

💡 Why This Matters

🌍 Real World

Breaking out of loops early is useful when searching for a specific item in a list, like finding the first available seat in a theater or the first error in a log.

💼 Career

Understanding how to control loops with break statements is important for efficient programming and is used in many software development tasks.

1

Create the array of numbers

Create an integer array called numbers with these exact values: 3, 7, 10, 15, 20.

C++

# Create the array called numbers with values 3, 7, 10, 15, 20
// Your code here

Need a hint?

Use curly braces {} to list the values inside the array.

2

Set the limit value

Create an integer variable called limit and set it to 12.

C++

int numbers[] = {3, 7, 10, 15, 20};
// Create the integer variable limit and set it to 12
// Your code here

Need a hint?

Use int limit = 12; to create the variable.

3

Use a for loop with break

Write a for loop using int i = 0 to i < 5 to check each number in numbers. Inside the loop, use an if statement to check if numbers[i] is greater than limit. If yes, use break to stop the loop.

C++

int numbers[] = {3, 7, 10, 15, 20};
int limit = 12;
// Write a for loop from i = 0 to i  limit, break the loop
// Your code here

Need a hint?

Use for (int i = 0; i < 5; i++) and inside it check if (numbers[i] > limit) then break;.

4

Print the first number greater than the limit

After the loop, print the message "First number greater than 12 is: " followed by the value numbers[i].

C++

#include 

int main() {
    int numbers[] = {3, 7, 10, 15, 20};
    int limit = 12;
    for (int i = 0; i  limit) {
            break;
        }
    }
    // Print the message and numbers[i]
    // Your code here
}

Need a hint?

Use std::cout to print the message and the number.
