Event-Based Triggers Using Function Pointer Array

Code

#include <stdio.h>
#define EVENT 5
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 (*fPtr[EVENT])() = {on_button, on_timer, on_uart, on_power, on_error};

    if(event_code < EVENT){
    	(*fPtr[event_code])();
    }
    else{
    	printf("Unhandled Event\n");
    }
}


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