Question

I tried to follow google c++ style guide . i have a setter for private memeber – age.

My problem is what should be the name of the setAge argument?
In java i have both the same name and ditinguish between them by using the this keyword.

void setAge(int age){
     this.age = age;
} 

What is the coding style to do this in c++ (google coding style is preferred).

Answer 1

The google C++ coding standards suggest that you add a trailing underscore to class data members. I think it is very important to follow this, otherwise you are guaranteed to hide a class data member with a local variable name.

Concerning getters and setters, I personally find getX and setX convenciton tedious, when it is obvious what a method does.

int age() const; // gets age, what else could it do?

void age(int age); // sets age, following the principle of least surprise.
