To figure out what card is The present card, I've A non-public member integer variable termed Id that is a part of the Card object. A worldwide variable identified as globalId (initialized to 0) is incremented as a go to the website brand new card is made and Card's Id takes on the value of globalId. Each Card Id while in the Rolodex is exclusive identifier - at least, that may be what I am hoping to accomplish.
