title: My C "Hello, world!" program isn't compiling
body: <p>I wanted to learn C, so I decided to start a C project and try out the canonical "Hello, world!" program in Visual Studio.</p>
  
  <p>So I put this code in</p>
  
  <pre><code>#import &lt;stdio.h&gt;
  
  main()
  {
      printf("Hello, world!");
  }
  </code></pre>
  
  <p>and got three errors:</p>
  
  <blockquote>
    <p>IntelliSense: cannot open source file "C:/.../stdio.tlh"<br>
    IntelliSense: identifier "printf" is undefined<br>
    IntelliSense: PCH warning: cannot find a suitable header stop location. An intellisense
    PCH file was not generated.</p>
  </blockquote>
  
  <p>Apparently I'm setting up my project wrong or I don't have the header files I need or something like that. </p>
  
  <p>I'm sure this seems like a really basic problem, but I haven't really used C before so I'm stuck and don't know what to do. What am I doing wrong and how do I fix it?</p>
