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 (*f0)(void) = &on_button;
    void (*f1)(void) = &on_timer;
    void (*f2)(void) = &on_uart;
    void (*f3)(void) = &on_power;
    void (*f4)(void) = &on_error;

    void (*ops[5])(void) = {f0,f1,f2,f3,f4};

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

}

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