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

void (*func_arr[])() = {on_button,
                            on_timer,
                            on_uart,
                            on_power,
                            on_error,
                            on_unhandled};

// Write your event dispatcher logic here
void handle_event(int event_code) {
    // Your logic
    if(event_code>4){event_code=5;}
    func_arr[event_code]();
}

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