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 (*fp[5])();
    fp[0] =on_button;
    fp[1] =on_timer;
    fp[2] =on_uart;
    fp[3] =on_power;
    fp[4] =on_error;
    if((event_code<0) ||(event_code>4) )
    {
        printf("Unhandled Event");
    } 
    fp[event_code]();
    
}

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