I wish this helpful for you Ok, so you can't do what you're trying to do directly in C++. There is a bit of a workaround though:
You can create a map, let's call it myCities:
code :
myCities[element] = new Ville(element);

will be helpful for those in need The String is a String literal, and so is always going to be interned when the class is loaded.

I wish this help you The compiler will concatenate the whole of "A" + "B" + "C" + "D" into a single constant - so in your first example, only a single string ends up created at all. That same string will be reused if you execute the same code multiple times. The constant is put in the class file, and when the class is loaded the VM checks whether an equal string is already in the string pool - so it will reuse it even if you have the same code in multiple classes.
You can verify that only a single string is in the constant pool within the class with javap:
code :
javap -v Test

Constant pool:
   #1 = Methodref   #6.#17     //  java/lang/Object."<init>":()V
   #2 = String      #18        //  ABCD
   #3 = Fieldref    #19.#20    //  java/lang/System.out:Ljava/io/PrintStream;
String s1 = "A";
String s2 = new String("A");
public static void foo() {
    for (int i = 0; i < 5; i++) {
        String s1 = "A";
        String s2 = new String("A");
    }
}

it fixes the issue In the w3c specification this sentence exists: , It's a known problem with Chrome, hopefully it'll get fixed soon.

it helps some times Suppose following is the piece of code, how many string objects are created and where(StringPool or heap memory) Mention the references which are pointing to the appropriate objects.
code :
String s1 = "abc";
 String s2 = s1;
String s3 = new String("abc");
String s4 = s3;

wish help you to fix your issue You don't need attr_accessor since you are using ActiveRecord.
Remove this line
code :
attr_accessor :email, :password, :password_digest
