When using a function,

In the a. function , a is a class-generated variable, and a. to the right of a. indicates a member function in the variable a and means to execute the function.

On the other hand, the function (a) is executed by putting a as an argument in the general function.

Usually a. function like this, Ah, the variable a is a class-type variable.You can think of it as .
