C++ is a general-purpose programming language created by Bjarne Stroustrup as an extension of the C programming language. Contrary to C, it's a multi-paradigm language.
C++ was designed with a bias toward system programming and embedded, resource-constrained software and large systems, with performance, efficiency, and flexibility of use as its design highlights. Although complex, it's expert friendly for those cases where you need it.
See our Node-RED project where it was especially suitable.
#include <iostream>
int main()
{
std::cout << "Hello, world!" << std::endl;
}
void Client::writePingResp()
{
// RAII style resource management
std::lock_guard<std::mutex> locker(writeBufMutex);
if (2 > writebuf.freeSpace())
writebuf.doubleSize();
writebuf.headPtr()[0] = 0b11010000;
writebuf.advanceHead(1);
writebuf.headPtr()[0] = 0;
writebuf.advanceHead(1);
setReadyForWriting(true);
