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) {
    // Your logic
    void (*arr[5])()={on_button, on_timer, on_uart, on_power, on_error};
    switch (event_code){
        case 0:{
        (arr[0])();
        break;
        }
        case 1:{
        (arr[1])();
        break;
        }
        case 2:{
        (arr[2])();
        break;
        }
        case 3:{
        (arr[3])();
        break;
        }
        case 4:{
        (arr[4])();
        break;
        }
        default:
        printf("Unhandled Event");
        break;
    }
}

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