title: How to write a Hello World in C
body: <p>I wrote little program to print "Hello world" in C. I'm not a C programmer, but I liked to try it. In my program there is an error. Please tell me what is it?
  This is my program:</p>
  
  <pre><code>int main(){
      printf("Hello World");
  }
  </code></pre>
