Thank you both for your comments. Sometimes Google just does not give the best answer.
First: Copying from the PlatformIO window re-formats the printed characters.
Not withstanding, I have done the Arduino-way thing, and am used to doing things that way. My idea of an interactive terminal send me to places I have never been. I have accidentally touched the special escape characters in a Python program. I am hoping to put them to good use in a C++ program.
Is the iostream-cout process Arduino or real C++ or both? Mostly C++
Do I need to use the iostream-cout way or can i just use print statements? I think not.
Is one better than the other? The Arduino way is more direct on an Arduino.
Some of the information that I am finding from Google is old and outdated(depreciated).
I am struggling to find something that has been done before but is not done the same way anymore. I assume that it is still possible but is done in a way that I have never seen. The error message that I get is “iostream not found”. I have gone through the PlatformIO library and Google to look for possibilities but run into references to extinct software and software out of my framework…
I am using an Arduino Mega 2560 clone in the Arduino framework.
And yes. Now that I am venturing away from pure Arduino I am just starting to see the differences from real C++.
Specifically, it now seems that the following library may for the C++ proper language and not Arduino C.
