Dynamic array length in struct

Question

What I want to do is make a struct that has an array of another struct, and I want to set the size of the array at runtime. Is there any way to do that? Struct is like:

struct MyStruct
{
  AnotherStruct list[];
  int key;
  bool isLeaf;
}

Answer 1

One way is:

#include <vector>

struct MyStruct
{
    std::vector<AnotherStruct> list;
    int key;
    bool isLeaf;
};

If you are new to vectors you can read about how to use them in any C++ reference.
