Previously, comparing C++Builder classic and Clang compilers I regreted than CodeGuard tool doesn't work with Clang. Fortunately, there are other tools which can help you to profile program code and detect memory leaks. The Dataleaker is the one of these tools.

Submitted by st on Sat, 09/02/2019 - 16:02

According to specification, "...constructor is a special non-static member function of a class that is used to initialize objects of its class type". In addition to basic concepts, C++11 introduces move constructors, initializer list type and brace-enclosed lists of comma-separated initializers.

C++11 containers: move semantic vs pointers

Submitted by st on Thu, 22/11/2018 - 13:34

Motivation

C++11 has introduced the move semantic which can also be used in containers instead of "old-school" pointers. The specific containers owning objects has been proposed earlier by third-party libraries like Boost (for example, ptr_map or ptr_vector).

Submitted by st on Mon, 12/11/2018 - 15:25

In the case of linked circular list you need to add some checks to avoid memory corruption.

Full example (compiled OK with GCC 8.x)

Submitted by st on Sat, 28/10/2017 - 19:27

Delphi case

Delphi supports interfaces natively. Any variable of variant type can store an interface like any allowed data types.

C++Builder: classic compiler vs clang

Submitted by st on Mon, 24/07/2017 - 20:30

Pro et contra

I use C++Builder 10.1 (Berlin) that proposes both 'classic' bcc32 compiler and new clang bcc32c. Whether do you rather to use classic compiler or to switch to clang? The answer is not quite simple.

The advantages of new clang compiler:

Using Delphi library with C++ Builder

Submitted by st on Thu, 29/09/2016 - 12:23

Since early XE versions C++ Builder supports Delphi units directly added in C++ project and compiles them as well as C/C++ source. However, this approach has several drawbacks:
