I have a C++ class with a double data type as a member variable. I want to initialize the variable during the declaration time. I am wondering which is the correct/better way to implement it:

class foo
{
    double first-method{0};
    double second-method{0.0};
};

Looks to me that both should work just fine. But what is the harm in clearing the concept by putting it out here instead of obsessing over it.

If you're asking what each means, they're equivalent. If you're asking which is better, it's off-topic. – Passer By Apr 13 '22 at 11:20
it is not quite clear what you are asking. It is the question about the difference betwee `0` and `0.0` used to initialize a `double` ? – 463035818_is_not_an_ai Apr 13 '22 at 11:23
Looks like there is already a discussion here: https://stackoverflow.com/questions/1384434/c-difference-between-0-and-0-0, will remove the question soon – DonBaka Apr 13 '22 at 11:24
fun fact: `0` is an octal literal, but also that doesn't make any difference here. – 463035818_is_not_an_ai Apr 13 '22 at 11:25
