Event-Based Triggers Using Function Pointer Array

Code

#include <stdio.h>

typedef void (*fun)();

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) {

    /* intilize the fun_ptr array. */ 
    fun Fun[5] = {  on_button,
                    on_timer,
                    on_uart,
                    on_power,
                    on_error 
                };

    /* calling the event handler. */
    Fun[event_code]();

} else {
    printf("Unhandled Event");
}

}

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