+A quick run of the above code block in visual mode in neovim runs by <br />
+:!g++ -std=c++20 /tmp/vim_cpp_exec.cpp -o /tmp/vim_cpp_exec &amp;&amp; /tmp/vim_cpp_exec <br />
+</p>
+
+<p>
+which one can set the keymapping in vimrc file by <br />
+<code>vnoremap &lt;leader&gt;pp :w! /tmp/vim_cpp_exec.cpp&lt;CR&gt;:!g++ -std=c++20 /tmp/vim_cpp_exec.cpp -o /tmp/vim_cpp_exec &amp;&amp; /tmp/vim_cpp_exec&lt;CR&gt;</code><br />
+</p>
+
+<p>
+Just selecting the code and pressing ',pp' (here &lt;leader&gt; is mapped to ',')<br />
+Which gives the following ouput:<br />
+Data 1: 42, Data 2: 77<br />
+Data 1: 3.14, Data 2: 2.718<br />
