Problem Statement

Write a C++ program that reads an array of N integers and a target value, then performs linear search to find its index.

Input Format

First line: N and Target. Second line: N space-separated integers.

Output Format

Print the index of the target, or -1 if not found.

Constraints

1 <= N <= 1000

Sample Input

5 30
10 20 30 40 50

Sample Output

2

Explanation

Searches for target element sequentially from left to right.

Starter Code

#include <iostream>
#include <vector>

int main() {
    int n, target;
    if (std::cin >> n >> target) {
        std::vector<int> arr(n);
        for (int i = 0; i < n; i++) {
            std::cin >> arr[i];
        }
        // Write your code here
    }
    return 0;
}

Intermediate

Embedded systems rely on efficient low-level programming to interact directly with hardware. In this course, you will learn how to write practical Embedded C programs used in real microcontroller-based systems. Rather than focusing only on theory, this course follows a practice-driven approach. Each lesson includes hands-on coding exercises that simulate real firmware development tasks used
