Is Full

Easy Queue: Array Implementation
Solve in Playground →

Problem Statement

Write a C program to check whether a fixed-size array-based queue is full (print 1 if full, 0 otherwise).

Input Format

An integer representing the number of elements enqueued into the queue.

Output Format

Print 1 if rear == MAX - 1, else 0.

Constraints

0 <= elements <= MAX

Sample Input

5

Sample Output

1

Explanation

Compare the rear index with MAX - 1 to determine if maximum queue capacity has been reached.

Starter Code

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

#define MAX 5

struct Queue {
    int arr[MAX];
    int front;
    int rear;
};

int main() {
    int count;
    if (scanf("%d", &count) == 1) {
        struct Queue q;
        q.front = 0;
        q.rear = -1;
        for (int i = 0; i < count && i < MAX; i++) {
            q.rear++;
            q.arr[q.rear] = i;
        }
        // Write your code here to check if queue is full
    }
    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
