Problem Statement

Write a C program to search for a specific element in a circular queue and return its 0-based relative index from front.

Input Format

Capacity, n elements, and target value to search.

Output Format

Print relative position index, or -1 if not found.

Constraints

1 <= n <= capacity <= 50

Sample Input

5 4
10 20 30 40
30

Sample Output

2

Explanation

Iterate through the circular buffer elements from front to rear checking for a value match.

Starter Code

#include <stdio.h>
#include <stdlib.h>

int main() {
    int cap, n, target;
    if (scanf("%d %d", &cap, &n) == 2) {
        // Write your code here for circular queue search challenge
    }
    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
