kik-bot-api-unofficial-cpp is an xmpp client for writing unofficial bots towards Kik xmpp server, it follows the same method as the python version, but there will be some new features such as the abilty to send images and more.
there are stages each stage represents a functionality for example stage1 is the xmpp client sending messages to a particular user, stage2 will be about sending an image to a particular group. and stage3, etc are now being thought of, once you've decided which stage you will be using make sure to always check the source code since you will always have to add something such as how you want the bot to respond, etc. after you're done gathering you can use g++ to compile the particular stages together and run it, and now you have a smooth running bot(and note that the user and pass that you put in stage1 will always be where the bot logs in from).
Note: Make sure to look at the code for documentation per each stage.
