Break statement in C - Mini Project: Build & Apply

Using the Break Statement in C

📖 Scenario: You are creating a simple program that searches for a specific number in a list of numbers. Once the number is found, the program should stop searching immediately to save time.

🎯 Goal: Build a C program that uses a break statement inside a for loop to stop searching when the target number is found.

📋 What You'll Learn

Create an array of integers with exact values

Create a target number variable

Use a for loop to search the array

Use a break statement to stop the loop when the target is found

Print the index where the target was found or a message if not found

💡 Why This Matters

🌍 Real World

Searching for a value quickly in a list is common in many programs, like finding a contact in your phone or a product in a store.

💼 Career

Understanding how to stop loops early with break helps write efficient code, which is important for software developers and engineers.

1

Create the array of numbers

Create an integer array called numbers with these exact values: 3, 7, 1, 9, 5.

C

int numbers[] = {3, 7, 1, 9, 5};
// Your code here

Need a hint?

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

2

Set the target number to find

Create an integer variable called target and set it to 9.

C

int numbers[] = {3, 7, 1, 9, 5};
int target = 9;
// Your code here

Need a hint?

Use int target = 9; to create the variable.

3

Search the array using a for loop and break

Write a for loop using int i = 0 to i < 5 to check each element in numbers. Inside the loop, use an if statement to check if numbers[i] equals target. If yes, use break to stop the loop.

C

int numbers[] = {3, 7, 1, 9, 5};
int target = 9;
int index = -1;
for (int i = 0; i < 5; i++) {
    // Your code here
}

Need a hint?

Use break; inside the if block to stop the loop.

4

Print the result

Write a printf statement to print "Found target at index: %d\n" with the variable index if index is not -1. Otherwise, print "Target not found".

C

int numbers[] = {3, 7, 1, 9, 5};
int target = 9;
int index = -1;
for (int i = 0; i < 5; i++) {
    if (numbers[i] == target) {
        index = i;
        break;
    }
}

// Your code here

Need a hint?

Use printf with %d to show the index.
