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

    if(event_code >=0 && event_code <=4) {
        return func_ptr[event_code]();
    } else {
        printf("Unhandled Event\n");
    }

}

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