Question

I have a class called CoolMenuItems

class CoolMenuItems
{
public:
    CoolMenuItems();
    ~CoolMenuItems();

    struct MenuItemOne
    {
        int id;
        uint32 type;
        uint32 subtype;
        String name;
    };

    struct MenuItemTwo
    {
        uint32 subtype;
        String name;
    };
}

This is just the bare bones of the class… I want to have two arrays, one of MenuItemOne, and one of MenuItemTwo, and these arrays would have the following. These arrays I want to initialize like:

MenuItemOne a[] =
{
    {1, EQData::EQ_EFFECT_TYPE_PARAMETRIC,       0,                                              T("Parametric")},
    {2, EQData::EQ_EFFECT_TYPE_FILTER_LOW_PASS,  EQData::EQ_FILTER_TYPE_FILTER_BUTTERWORTH_12DB, T("Low Pass")},
};

MenuItemTwo b[] =
{
    {EQData::EQ_FILTER_TYPE_TRHU,                      T("Thru")},
    {EQData::EQ_FILTER_TYPE_BUTTERWORTH_6DB,           T("6  dB Butterworth")},

};

only, with more elements than just two…

I want to set it up so that I can create a new CoolMenuItems object with

CoolMenuItems *cmi = new CoolMenuItems();

so that I can access those array elements via

cmi->a[1];

Can you modify your code like this

class CoolMenuItems
{
public:
    CoolMenuItems();
    ~CoolMenuItems();

    struct MenuItemOne
    {
        int id;
        uint32 type;
        uint32 subtype;
        String name;
    };

    struct MenuItemTwo
    {
        uint32 subtype;
        String name;
    };
std::vector<MenuItemOne> menuItemOne;
std::vector<MenuItemTwo> menuItemTwo;
}

So that you can initialize the elements of struct and push_back the struct into the std::vector, all the memory to be allocated and to be freed will be taken care of by the std::vector

MenuItemOne a = {1, EQData::EQ_EFFECT_TYPE_PARAMETRIC, 0,T("Parametric")};

menuItemOne.push_back(a);

Similarly for MenuItemTwo.
If you have a different requirement then please give more details.
