Any of those help You can't increment an array. What would that even mean?
Try this:
code :
#include <iostream> 
using namespace std;

int main ()
{
   char s[] = "hello";
   char t[] = "house";

   char *ss = s;
   char *tt = t;
   while (*ss++ = *tt++);

   cout << s << endl;
}

like below fixes the issue Because an object is copied before thrown.
Even if the parameter a of foo points to an instance of B at run-time, what matters is the compile-time type of the throw expression. So, effectively, the instance of B is passed to the copy-constructor of A (which is legitimate since B inherits A) and a new A instance created and then thrown.

this one helps. Your PATH may contain spaces. First, properly quote it. And, you might have another jdk earlier in the PATH (so set it first). Something like
code :
set "PATH=c:\amir\jdk1.7.0_45\bin;%PATH%"
cd c:\myutilities\auth
java -jar auth.jar
@echo off
setlocal
set "PATH=c:\amir\jdk1.7.0_45\bin;%PATH%"
java -jar c:\myutilities\auth\auth.jar
endlocal

this will help The problem is that you are created a nested function and it will not be called. You need to create a function with global scope and change it inside window.onload
code :
var klik; //declaring a global variable.
window.onload = function(){
  const navn = document.querySelector('.navn > input');
  const password = document.querySelector('.password > input');

   //changing it to the function
  klik = function() {
      console.log(navn);
      console.log(password);
  }
}
<center>
            <p class="navn1">LOG IND</p>
        </center>

        <div class="navn">
            <span id="navn">Navn: &nbsp;</span> <input type="text" 
             class="inavn"><br><br>
        </div>

        <center>
            <div class="password">
                <span id="pass">Password: &nbsp;</span> <input 
                type="text"><br>
            </div>

            <br><br>

            <button onClick="klik()" class="logind">Log ind</button>
            <br>
