title: calling function whose name is class name itself?
body: <p>I do not know what methodology they use since the code base is <strong>huge</strong>.</p>
  
  <p>It defined a class like this:</p>
  
  <pre><code>class ABC {
      member_func(string c);
  };
  
  main() {
      ABC("").member_func("this random string");
  }
  </code></pre>
  
  <p>What is the missing code that would enable us to call <code>ABC("");</code>?</p>
  
  <p>I did not see any object of that class created anywhere.</p>
