Using component interactions (advanced)

This example demonstrates receiving button clicks and sending response messages.

#include <dpp/dpp.h>
 
using json = nlohmann::json;
 
int main()
{
 
    dpp::cluster bot("token");
 
    bot.on_button_click([&bot](const dpp::button_click_t & event) {
        if (event.custom_id == "10") {
            event.reply(dpp::ir_channel_message_with_source, dpp::message("Correct").set_flags(dpp::m_ephemeral));
        } else {
            event.reply(dpp::ir_channel_message_with_source, dpp::message("Incorrect").set_flags(dpp::m_ephemeral));
        }
    });
 
    bot.on_message_create([&bot](const dpp::message_create_t & event) {
        if (event.msg.content == "!ping2") {
            bot.message_create(
                dpp::message(event.msg.channel_id, "What is 5+5?").add_component(
                    dpp::component().add_component(
                        dpp::component().set_label("9").
                        set_style(dpp::cos_primary).
                        set_id("9")
                    ).add_component(
                        dpp::component().set_label("10").
                        set_style(dpp::cos_primary).
                        set_id("10")
                    ).add_component(
                        dpp::component().set_label("11").
                        set_style(dpp::cos_primary).
                        set_id("11")
                    )
                )
            );
        }
    });
 
    bot.start(false);
 
    return 0;
}

This code will send a different message for correct and incorrect answers.
