Problem Statement

Write a C program to simulate a producer-consumer buffer using a circular queue.

Input Format

Buffer capacity and number of production/consumption steps.

Output Format

Print produced items that successfully entered the circular buffer.

Constraints

1 <= capacity <= 50

Sample Input

3 5
1 100
1 200
1 300
0
1 400

Sample Output

200 300 400

Explanation

Producers push items into the circular buffer (if not full), and consumers remove items from the front (if not empty).

Starter Code

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

int main() {
    int cap, steps;
    if (scanf("%d %d", &cap, &steps) == 2) {
        // Write your code here for producer consumer simulation
    }
    return 0;
}

Limits

  • Time Limit: 1s
  • Memory Limit: 256MB

Embedded C Programming

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
