Mobile android applications developed in C++ Builder requires permissions to use some part of mobile devices (sensors, camera etc..). These should be allowed by the user. an these permissions can be checked over the project options from Project > Options > Application > Uses Permissions section. Some of these permissions were listed in this document…

Every implementation of the C++ Standard Library like one included to Embarcadero RAD Studio C++ compilers provides two ways for (pseudo-)random numbers generation: old-fashioned facilities from <cstdlib> and modern facilities provided by <random>.
Facilities from <cstdlib>
There are two very simple functions provided by the C random library: std::srand() and std::rand().
The iterator library that is part of the C++ Standard Library provides the following helpers for writing generic code:
#include <iterator> // helpers are defined here
template<class Container>
void foo(Container& c)
{
// Generic way to obtain (constant)…
Since C++11 there are elegant way to access each element of a containers (or, more generally, sequences) – so called range-for-statement. The syntaxes are follow:
template<class Container>
void foo(Container& container)
{
for (auto element : container)…

C++ is a strong and faster programming language, this feature really important on dynamic operations running less than in milliseconds of intervals. C++ is one of the best to analyze video camera images, it is good to analyze video image operations by using very modern…
In this article we will add some quick methods to show how to use basic components in C++ Builder. Most of component properties and methods are same in VCL and FMX projects. If you are a beginner we highly recommend you to watch this Introduction To C++ Windows Development…
Let’s slightly modify the example from The Move Iterator Adapter in C++ post:
#include <algorithm>
#include <list>
#include <string>
#include <vector>
/// @warning BUG! PLEASE, DON'T USE!
auto deep_copy_to_list(const std::vector<std::string>& src)
{
std::list<std::string> dst; // constructs the empty list
copy(cbegin(src), cend(src)…
