In C language, what are Evaluation, Precedence and Association?

The "C" compiler evaluates expressions according to precedence and associativity rules.

If the expression contains operators of different precedence, precedence rules will be considered.

If expression Contains the same priority, the associativity rules are considered, that is, from left to right (or right to left).
