      The compiler is just warning you that order of initialization will be different than what you requested.
      You need to initialize the variables in the constructor's initializer in the order they're declared in the class. E.g:

      class X
      {
          X()
              : a(0), b(0)  //< In the same order they're declared in the class, if you use b(0), a(0) it will generate the warning.
          {
          }
      
          int a;
          int b;
      }
