title: Nested structure with the same name in C
body: <p>I have a exercice that I have to realise a structure to match this line in C</p>
  
  <pre><code>int main() {
       t_foo foo;
       foo.foo.foo = 0;
       return (0);
  }
  </code></pre>
  
  <p>I tried to create a nested structure, but I can't create with a same name. Have you an idea ?</p>
