=, =, -=, *=, /=, %=, &=, ^=, |=, <<= ,>>=

Using "=", a = 10; is equivalent to a = a 10;. "-=" is the same thing.

Expansion:

"==", "!="

means when using "==" The judgment is like if (a==10). If a is equal to 10, it will be executed. If it is not equal, the statement in the if will be skipped and the subsequent statements will be executed. "!=" means to judge whether it is not equal, and execute if it is not equal.
