title: Cannot open source file "stdio.h" in Visual Studio Code
body: <p>I'm new to C and this is my first project using visual studio. I have #include &lt;stdio.h&gt; in the first line of the code but there is an error &quot;cannot open source file &quot;stdio.h&quot; C/C++ (1696)&quot;. I have installed the Microsoft C/C++ extension. I am happy to clarify anything. Thank you!</p>
