I've been coding in c++ for quite a while. today I've stumbled upon one table. it was depicting Logical operators and their symbols. Till now all of the operators I've ever used were : && , || , !. However the table tells that there are more. I haven't really cared about them except for two: "OR EQUAL" and "AND EQUAL".I have searched the internet for them. Sadly found no proper results. Here is a picture of the table and code below showing my point of view how those two operators could work.
Have you ever used these operators, if so how?
