Event-Based Triggers Using Function Pointer Array

Code

#include <stdio.h>

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 unhandled_event() {
    printf("Unhandled Event");
}

// Write your event dispatcher logic here
void handle_event(int event_code) {
    // Your logic
    void (*event_handler[])(void) = {

        on_button,
        on_timer,
        on_uart,
        on_power,
        on_error,
        unhandled_event,
    };

    if(event_code > 4 || event_code < 0)
    {
        event_code = 5;
    }

    event_handler[event_code]();
}

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