Event-Based Triggers Using Function Pointer Array

TOI YEU HUST,  CAM ON ANH ANH DO MIXI,

#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 (*fp[5]) () ={on_button, on_timer, on_uart, on_power, on_error};
// Write your event dispatcher logic here
void handle_event(int event_code) {
      if(event_code>=0 && event_code<=4)
      return fp[event_code]();
      else
       printf("Unhandled Event");
}

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