title: c++: I am trying to reverse the order of words in string (not the whole string)
body: <pre><code>#include &lt;iostream&gt;
  #include &lt;vector&gt;
  using namespace std;
  
  void RevStr (char *str)
  {   
      if(*str !=0)
      {
          vector&lt;char&gt; v1;
  
          while((*str != ' ')&amp;&amp;(*str !=0))
              v1.push_back(*str++);
          // trying to not add space in the last word of string
          if(*str !=0)
          {
              v1.push_back(' ');
              str++;
          }
          RevStr(str);
          cout&lt;&lt;*str;
      }
  
  
  }
  int main()
  {
      RevStr("hello world!");
      cout&lt;&lt;endl;
  
  }
  </code></pre>
  
  <p>I want to change the order of words in the string  for example " how are you" => "you are how"</p>
  
  <p>I am having some problem, its not printing correctly (print only w), please help me and tell me what i did wrong. However i know that I should not call "cout&lt;&lt;*str;
  " since i am inserting the "array of char" in stack (recurssion) but i dont know what i need to do.</p>
