Event-Based Triggers Using Function Pointer Array

Code

#include <stdio.h>

typedef void (*OperationFunc)();

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
    OperationFunc func_array[5] = {&on_button, &on_timer, &on_uart, &on_power, &on_error};
    if ((event_code < 0) || (event_code > 4)) {
        printf("Unhandled Event\n");
        return;
    }
    
    func_array[event_code]();
} 

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