What is the difference??

[basheer.md]

Hi all,

What is the difference in both types of intializations? .

Class Abc {

int x,y,z;

public:
Abc() { x=0, y=0, z=0; }
};
Class Abc {
int x,y,z;

public:
Abc():x(0),y(0) ,z(0) { }
};
Is there any difference in these 2 kinds of intializations? . Which one
could be better to use?.

Thanking you.

The first one is not initialization, it's assignment.

The answer to your question is in the FAQ:

Thats a syntax error:
Abc() { x=0; y=0; z=0; }

};
Class Abc {
int x,y,z;

public:
Abc():x(0),y(0) ,z(0) { }
};

The first would allocate and then assign, the second allocates +
initializes simultaneously.

You sure about that?

No, it's not. It actually achieves the same effect as:

Abc() { x=0; y=0; z=0; }

Look up 'comma operator'.
