Enum scope is not accessible through structure in Class in C++

There is one problem I am facing in access and initializing the enum and structure as described There is one Header file defined as for sample.h have content as

class MyClass{

   enum M1 {
          MY_VAL1 = 0, 
          MY_VAL2,
          MY_VAL3
    };

   enum M2 {
          MY_VA1 = 0, 
          MY_VA2,
          MY_VA3
    };


   enum M3 {
          MY_V1 = 0, 
          MY_V2,
          MY_V3
    };

  struct val {
        M1 obj1;  
        M2 obj2;
        M3 obj3;
   };  

};

In the sample.cpp I am initializing or accessing as

#include "sample.h"

MyClass mObj = { {MY_VAL1}, {MY_VA1}, {MY_V1} };

But always complain about that "MY_VAL1", "MY_VA1", "MY_V1" not defined in the scope.

All of these enums are not defined in the scope of main, instead they are defined inside your class. Use scope resolution operator (i.e. ::) to solve this. Note that using :: is still problematic in your case, since the enums are private. Change them to public for the :: to work.

... 
main(){
...
        int x = MyClass::MY_VA1;
...
    }

I'm not using your example, as it gives other errors...

Your enum types are not public, and you are not qualifying the member type names. It seems that you want some member variables, instead of declaring struct MyClass::val:

class MyClass{
public:
   enum M1 {
          MY_VAL1 = 0, 
          MY_VAL2,
          MY_VAL3
    };

   enum M2 {
          MY_VA1 = 0, 
          MY_VA2,
          MY_VA3
    };


   enum M3 {
          MY_V1 = 0, 
          MY_V2,
          MY_V3
    };

    M1 obj1;
    M2 obj2;
    M3 obj3;
};

static const MyClass foo = { MyClass::MY_VAL1, MyClass::MY_VA1, MyClass::MY_V1 };
