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
    if((event_code < 0) || (event_code > 4)){
        printf("Unhandled Event");
    }

    else if(event_code == 0){
        on_button();
    }

    else if(event_code == 1){
        on_timer();
    }

    else if(event_code == 2){
        on_uart();
    }

    else if(event_code == 3){
        on_power();
    }

    else if(event_code == 4){
        on_error();
    }

}

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