Btw. are you aware that a static member variable is very different from a non-static? A static member variable only has the scope of the class but there is only one global storage. I.e. if one instance changes the value it will be changed for all other instances as well (as static member variables actually doesn't belong to any instance).

Definition of static variables in header files isn't a good thing in general. The header might be included more than once and so you get an ODR violation. (ODR - One Definition Rule). Qualifying this inline tells the compiler explicitly to sort it out by itself. FYI: Static data members.

What about static inline int m=INT_MIN;?

| Apr 30, 2020 at 7:57 | comment | added | Jaswant Arya | I have commented the line which shows the error. I know that I should not use static as it will be static for all the instances but what is the meaning of this error- "non-const static data member must be initialized out of line" | |
| Apr 30, 2020 at 7:55 | comment | added | Jaswant Arya | I have commented to the line which shows the error. | |

I don't think I understand your reasoning for using static data member. static data members are shared between all instances of the class, do you really want every single object of your class to change value of m?

| Apr 30, 2020 at 7:46 | comment | added | theWiseBro | "I need to update the value of variable m. Therefore I am using "static int" data type." - What does this even mean? Do you mean keeping it shared across all instances? | |
| Apr 30, 2020 at 7:46 | comment | added | Some programmer dude | Please copy-paste the errors as text into the question. Then make sure that the minimal reproducible example you show actually causes the error. And please add a comment on the line where you get the error. | |
| Apr 30, 2020 at 7:46 | comment | added | molbdnilo | Why don't you just use a global variable? (And why is this a class?) | |

Your posted code does not use static anywhere, please show us the code that actually generates that error.
