title: how many std::string copies are being made?
body: <pre><code>string str1("someString");
  string str2 = string(str1);//how many copies are made here
      //copy2 = copy1?
  </code></pre>
  
  <p>When you assign a string with string(otherString), does it copy the value in the parentheses then copy that value to the variable?</p>
