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) {
    if(event_code>4 || event_code<0)
    {
        printf("Unhandled Event");
        return;
    }
    void (*arr[])()={on_button,on_timer,on_uart,on_power,on_error};
    arr[event_code]();

    /*
    switch(event_code)
    {
        case(0):
        {
            on_button();
            return;
        }
        case(1):
        {
            on_timer();
            return;
        }
        case(2):
        {
            on_uart();
            return;
        }
        case(3):
        {
            on_power();
            return;
        }
        case(4):
        {
            on_error();
            return;
        }
    }
    */
}

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