As embedded electronics continues to transform our lives, engineers around the globe are looking for ways to increase their coding chops. To help engineers meet this need, element14 has unveiled Code Exchange-- a place where engineers can help each other.
In object oriented designs, there are times when you replace an object by another. Example: when you store an object into an STL container. In a lot of those cases, you create an object, and add it. The object in the container is a cop...
You may read guidelines that say: "never use an object as return value of a function. Because of performance reasons". Because the object is copied into the receiving variable when returning from the function call. That was true in C++...
task: Let's say that you are writing a C++ class, where the objects have to be sorted or compared.
In classic C++, you 'd write an operator overload for <, <=, == , !=, >= and >. In modern C++, you can get all that fun...
If you're interested to try out the latest C++26 options: The Windows port for GCC 15.1 is available for download.I installed GCC 15.1.0 (with POSIX threads) + MinGW-w64 13.0.0 UCRT - release 2. To install, download the zip file, ...
For an embedded design, I made a featherweight class. A C++ construct that used no more data or code size than a traditional C design.
class command {
public:
inline command(uint32_t steps, bool reverse) : cmd_(steps << 1 |...
