How to use C Libraries for Arduino code I have a code in Visual studio that I want to implement in Arduino. But
there is a problem. Many libraries usable in Visual Studio aren't usable
in the Arduino IDE. How can I use them in my Arduino code? To be
precise, the libraries I want to use are

#include &lt;iostream&gt;
#include &lt;iomanip&gt;
#include &lt;queue&gt;
#include &lt;string&gt;
#include &lt;math.h&gt;
#include &lt;ctime&gt;


I know I have &lt;iostream&gt; available in Arduino. &lt;math.h&gt; is also
available I think along with the &lt;string&gt; library. The main problem is
to how to use #include&lt;queue&gt; and its functions such as
priority_queue() and other functions of iosteam like .pop()? Any
help would be highly appreciated.
Some of the libraries you mention (iomanip, iostream, queue, string) are part of the STL - Standard Template Library. Whilst it does not ship with the IDE download, you can install it yourself. See The Standard Template Library (STL) for AVR with C++ streams - a port to the Arduino by Andy Brown.

I have some implementation notes here.

Be aware that a lot of Arduinos don't have much RAM, so you need to use libraries like this with caution.
