title: string in namespace std does not name a type
body: <p>This may just be a simple mistake that I'm not seeing, but 
  I think I'm simply doing something wrong. Don't worry I'm not using namespace std in my header
   functions or anything which seemed to be this person's issue [Question I read similar to 
  mine][1] [1]: <a href="https://stackoverflow.com/questions/5527665/weird-string-does-not-name-a-type-">Why am I getting string does not name a type Error?</a></p>
  
  <p>I am getting 4 errors right now:</p>

  <p>Here is my header file:</p>
  
  <pre><code>class Nouns
  {
      public:
          Nouns();
          std::string noun;
      protected:
      private:
          int rnp; // random noun picker
          std::string dog, cat, rat, coat, toilet, lizard, mime, clown, barbie, pig, lamp, chair, hanger, pancake, biscut, ferret, blanket, tree, door, radio;
          std::string nounGenerator()
  };
  </code></pre>
  
  <p>And this is my cpp file:</p>
  
  <pre><code>#include "Nouns.h"
  #include &lt;iostream&gt;
  
  Nouns::Nouns()

      rnp = rollRandObj.randNum;
  
      switch(rnp){
      case 1:
          noun = "dog";
