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 handle_event(int event_code) {
    void (*op[5])() = {on_button, on_timer, on_uart, on_power, on_error};
    event_code < 5 ? op[event_code]() : (void)printf("Unhandled Event");
}

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