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) {
    void (*Handle_Evenet_1[])()={on_button,on_timer, on_uart,on_power,on_error};

    int total_event =sizeof(Handle_Evenet_1)/sizeof(Handle_Evenet_1[0]);
    if(event_code >= 0 && event_code < total_event)
    {
        Handle_Evenet_1[event_code]();
    }
    else
    {
        printf("Unhandled Event");
    }
    // Your logic
}

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