For c programming language, what does it mean when you have an exclamation mark after an equal sign? ie:

x=y;
y=! x;
x=! y;

It has to be firstly understood that the exclamation mark is not at all associated with the equal mark. The correct way to write it is x = !y. This actually means that whenever "y" is true or false set, then it can be considered for sure that it returns zero or 1. I hope the answer has helped you.
