C++ Builder

Dynamic arrays are simulated in the C++Builder C++ by the class

template<class T>

using D2CArray = System::DynamicArray<T>;

This class is defined in d2c_array.h

Remark:

The simpler definition

template <class T> class DELPHIRETURN DynamicArray;

is not resolved correctly by C++Builder, if the generic TArray<T> class is in scope.

Portable

If the output is generated for other compilers std::vector is used instead of a DynamicArray.

MyFlexibleArray: array of Real;

->

DynamicArray < double > MyFlexibleArray;  // C++Builder

std::vector < double > MyFlexibleArray;   // other compiler 

This DynamicArray class has the properties Low, High and Length. By the Length property, the size of the array can be changed. Dynamic arrays are accepted as parameters only, if the type of the array is defined explicitly and if the function expects this type.
