Structs, and Arrays...

I want to make a struct that can hold an undifined array of other user defined structs.......

Ex:

Code:

---

typedef struct Info_Holder
{
    string        Name[];
    XHOLDER  xHolder[];  // another user defined struct

    Info_Holder()
    {
        xHolder[] = new xHolder();
    }
    ~Info_Holder()
    {
        delete[] xHolder;
    }
}

---

is that the right way to do it??? Can someone explain to me a better way cause this gives me errors...

You appear to be using class syntax. A struct is just a user defined type. All data, no functions...

Code:

---

typedef struct Info_Holder
{
    string        Name[];
    XHOLDER  xHolder[];  // another user defined struct
}

---

:)

In C++, the difference between a class and a struct is the default visibility of members. You must specifically define a group of functions or data to be public in a class, while in a struct that is the default. Otherwise, it is only convention that says classes have member functions and structs contain data.

As for the original question:

Code:

---

...
XHOLDER* m_xData;
...
Info_Holder() {
  m_xData = new XHOLDER[NUM_XHOLDERS];
}
...
~Info_Holder() {
  delete [] m_xData;
}

You also dont have to typedef your structs in C++. In C it is a customary practice to typedef structs, because declaring a variable of a struct type directly looked like this:

Code:

---

struct myDataType myVarName;

---

When you typedef:

Code:

---

typedef struct tagMyDataType{...} myDataType;

---

you can then declare using this format:

Code:

---

mDataType myVarName;
