Question

I have a struct in my header file

 struct Foo{
     timeval t;
     struct Bar b;
 }

and i also have another one for Bar in the same header file, and I have declared a class in the header file as well.

 class Layer{
      public:
              ...
              ...
      private:
              struct Foo myarray[];
 }

I want to declare an array of Foo in my header file and initialize it in my class constructor

 Layer::Layer(unsigned int size)
 {
       myarray = new Foo[size];
 }

but that returns an error when compiling.
error: incompatible types in assignment of ‘Foo*’ to ‘Foo [0]’

any idea how to fix this?

Answer 1

struct Foo myarray[]; should be struct Foo *myarray; if you’re going to go with it in a dynamic approach. Otherwise, if you want it to be an unspecified static I think it has to have an initialization list.
