Initialization of a variable of a static class inside the main

Question

I have a static variable in the class. I initialize that on a global scale his work is beautiful.

But when I try to initialize in the main linker, an error occurs. Why is this so.

class Myclass{

    static int iCount;
} ;

int main(){

  int Myclass::iCount=1;

}

And In the global scope, I have to specify the type of the variable as

int Myclass::iCount=1;

As in my class, I define iCount as an integer type, why not.

   Myclass::iCount =1 ; in //Global scope

Answer 1

The $ 9.4.2 / 7 section of C ++ Standard says:

Static data elements are initialized and destroyed just like non-local objects (3.6.2, 3.6.3).

class Myclass{

    static int iCount;
} ;
int Myclass::iCount=1;

int main(){
  /*** use Myclass::iCount here ****/
}
