How the "dist" works in constraint if we create the object every time vs one time

In reply to dave_59:

Hi Dave ,

I have a question regarding RNGs

I believe if the addr were declared as randc and No dist Constraint be present the above 2 Codes would have different results .

(a) If its not too much to ask could you give an example where the 2 Codes ( where one is
constructed repeatedly and the other randomized repeatedly ) would have different
results when the variable is declared as rand .

(b) From the above 2 Codes ( where one is constructed repeatedly and the other randomized
repeatedly ) does any one have a benefit over the other ?

 One point I can think of is when the Object is Constructed repeatedly it would consume 
 more memory
