different output depending on scopes

code below shows how if use assign a ref and then change the value w ptr in different scope, ref continues w the old value. Instead if do it at same scope, no. why? its cause the aux reference? thx https://code.sololearn.com/c77bC48EU746/?ref=app

"ref = n" == ref=100; If you try cout<<aux it gives 100 too, ref refers aux always.. e.g.: the first assignment of ref is the initialization of ref => address of aux, the 2nd assignment is a normal value assignment. There is a something wrong about ptr in "TEST=true" scope here instead, the variable it points no longer exists after "if(true)" block.. Here there's why.. https://stackoverflow.com/questions/6441218/can-a-local-variables-memory-be-accessed-outside-its-scope
