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 (*fb[5])() = {on_button, on_timer, on_uart, on_power, on_error};
    switch (event_code){
        case 0: fb[0](); break;
        case 1: fb[1](); break;
        case 2: fb[2](); break;
        case 3: fb[3](); break;
        case 4: fb[4](); break;
        default : printf("Unhandled Event");
    }
}

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