Event-Based Triggers Using Function Pointer Array

Code

#include <stdio.h>

typedef void (*event_fnc)(void);


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");
}

event_fnc triggers[5] = {
    &on_button,
    &on_timer,
    &on_uart,
    &on_power,
    &on_error};

// Write your event dispatcher logic here
void handle_event(int event_code) {
    if(event_code>= 0 && event_code<=4)
    {
        triggers[event_code]();
    }
    else
    {
        printf("Unhandled Event");
    }
}

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