-16

I've seen code example that had 

x += y

and I can't seem to find any explanation for this.

Please help. Thanks.

You can also combine the arithmetic operators with the simple assignment operator to create compound assignments. For example, x+=1; and x=x+1; both increment the value of x by 1.

    I up-voted, but your not technically supposed to answer duplicates, poorly written questions, or any questions that show no research effort. This question seems like all 3 of these things combined. –  May 26 '17 at 07:44

    Do you have a source for that? It's news to me. – Ryan Leach May 26 '17 at 07:51

    Also I saw a new Stack Overflow user that was looking for guidance, figured giving them an answer, as well as letting them know the etiquette seems a lot less abrasive then giving them no answers and having their question flagged / deleted. This community gets an awful bad rep sometimes with the way it deals with new users. – Ryan Leach May 26 '17 at 07:52

    Yes, I do have a source. See [How do I write a good answer?](https://stackoverflow.com/help/how-to-answer). Near the bottom it says _"Answer [well asked](https://stackoverflow.com/help/how-to-ask) questions"_ look at the third bullet point. –  May 26 '17 at 20:10
