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");
}

// Write your event dispatcher logic here
void handle_event(int event_code) {
    if(event_code < 0 || event_code > 4) printf("Unhandled Event");
    void (*states[5])() = {on_button, on_timer, on_uart, on_power, on_error};
    if(event_code == 0) states[0]();
    if(event_code == 1) states[1]();
    if(event_code == 2) states[2]();
    if(event_code == 3) states[3]();
    if(event_code == 4) states[4]();
    
}

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