warning: useless storage class specifier in empty declaration

Warning: useless storage class specifier in empty declaration

Solution:

Cause of such warning is declaration of data type without any variable when we explicitly writing the storage class.For example:

static struct Testa

     

      int a;

}; 

To solve this problem you have choices:

1.   

static struct Test{

     

      int a;

}x; 

2. 

struct Test{

     

      int a;

}; 

  

Another example:

extern enum Test{

     A,B,C

}; 

Solution:

1.

extern enum Test{

     A,B,C

}pqr;

2.

enum Test{

     A,B,C

};
