Hello everyone.
I'll ask this even at risk of being accused of not researching adequately.
My question (before longer reasoning) is: How does declaring (or defining,

Hi All,
char to char ** is compile error. why?
if i hava a string array. yes. it's not safe and it's better to use
vector<stringinstead.
but my point is the language feature.
char sex = {"Male", "Female" };

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

This is as boiled down as I can make it.
Here is my compilation command:
