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

// Write your event dispatcher logic here
void handle_event(int event_code) {
    // Your logic
    void (*trigger_fun_event[])() = {on_button,  on_timer ,on_uart,on_power,on_error, unhandled };
     
     if(event_code >=0 && event_code <= 4)
     return trigger_fun_event[event_code]();
     else
     return trigger_fun_event[5]();

}

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