How can I implement scheduling in C?

You can implement scheduling in C by using data structures like queues and algorithms such as Round Robin or Priority Scheduling.

Can you provide a simple example of Round Robin scheduling?

Sure! Here's a basic example:

#include <stdio.h>
#define MAX 10

struct Process {
    int id;
    int burst_time;
};

void roundRobin(struct Process processes[], int n, int quantum) {
    int remaining_time[MAX];
    for (int i = 0; i < n; i++)
        remaining_time[i] = processes[i].burst_time;

    int time = 0;
    while (1) {
        int done = 1;
        for (int i = 0; i < n; i++) {
            if (remaining_time[i] > 0) {
                done = 0;
                if (remaining_time[i] > quantum) {
                    time += quantum;
                    remaining_time[i] -= quantum;
                } else {
                    time += remaining_time[i];
                    remaining_time[i] = 0;
                    printf("Process %d completed at time %d\n", processes[i].id, time);
                }
            }
        }
        if (done)
            break;
    }
}

int main() {
    struct Process processes[] = {{1, 10}, {2, 5}, {3, 8}};
    int n = sizeof(processes) / sizeof(processes[0]);
    int quantum = 2;
    roundRobin(processes, n, quantum);
    return 0;
}

What are the advantages of using Round Robin scheduling?

Round Robin scheduling is simple, fair, and ensures that all processes get a chance to execute, which is great for time-sharing systems.
