StringStream in C++ is similar to cin and cout streams and allows us to work with strings. Like other streams, we can perform read, write, and clear operations on a StringStream object. The standard methods used to perform these operations are defined in the StringStream class.Want a Top ...
In C++, stream classes implementoperatorbool()which allows them to be implicitly converted to a boolean. This boolean indicates whether the streams are in a good or bad state. http://en.cppreference.com/w/cpp/io/basic_ios/operator_bool ...

The implementations favorIAsyncDisposableoverIDisposablewhen both interfaces are implemented. Extenders must override the new methods included to supportIAsyncDisposableinstances. IAsyncDisposableis beneficial when working with: Asynchronous enumerators, for example, in asynchronous streams. ...
You can now code complete in header files that are not directly part of the project (e.g., not part of a cpp/header unit pair.) Changing project options or the active platform will restart the server to match the new project settings. ...

std::flush applied to an output stream writes out pending output (characters that may still be in the streams buffer in memory, and have not been written out as yet). This manipulator may be used to produce an incomplete line of output immediately, e.g. when displaying output from a lon...
std::endl is more appropriate because if you are using buffered streams, std::endl will flush the buffer for you. Although in many cases you will want to be explicit and clear out the buffered streams yourself, it is always a good practice to be extra careful. ...
Topics. Those will be used mainly for sending data streams between nodes. Example: you’re monitoring the temperature of a motor on the robot. The node monitoring this motor will send a data stream with the temperature. Now, any other node can subscribe to this topic and get the data. ...
