C++ vector default into a members parameters : <p>New to low level coding, coming from php, how do you properly define a member default parameters with a vector ?</p>

<pre><code>     A(int x = 0, std::string y, 
std::vector&lt;std::string&gt; z = {0{"ScreenName","ID"}, ... } 
    ){
            switch(x){
                case 0: CreateNewPlayer(z["ScreenName"], z["ID"]); break;
                default:
                /* log function*/
                break;
              }
        }
    }
</code></pre>
