[C++] static member variable and static const member variable from www.cnblogs.com
Constexpr variables are constant and usable in constant expressions. Please refer static functions in c for more details. They are created in the code section;
Static Datatype Variable_Name = Value;
A static local variable is different from local variable. Static variables are variables that remain in memory while the program is running i.e. // |x| is initialized only once across five calls of |func| and the variable // will get incremented five.
Visibility Is The Same As The Automatic Local Variables.

In This Case, Value − It Refers To The.
Using the static keyword on a local variable changes its duration from automatic duration to static duration. Their lifetime is the entire program run. The syntax of the static variables in c is:
