Event-Based Triggers Using Function Pointer Array

Code

#include <stdio.h>

#define EVENT_MAX 5

void on_button() {
    printf("Button Pressed");
}
void on_timer() {
    printf("Timer Expired");
}
void on_uart() {
    printf("UART Received");
}
void on_power() {
    printf("Power On");
}
void on_error() {
    printf("Error Detected");
}

void (*handler[EVENT_MAX])() = {&on_button,
        &on_timer,
        &on_uart,
        &on_power,
        &on_error};

// Write your event dispatcher logic here
void handle_event(int event_code) {
    // Your logic
    if (event_code >= 0 && event_code < EVENT_MAX) {
        handler[event_code]();
    } else {
        printf("Unhandled Event");
    }
}

int main() {
    int event;
    scanf("%d", &event);
    handle_event(event);
    return 0;
}
