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 (*fptr[5])() = {on_button,on_timer,on_uart,on_power,on_error};
    if(event_code >= 0 && event_code <=4){
        fptr[event_code]();
    }else{
        printf("Unhandled Event");
    }
}
    

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