How to implement the finally statement in Java in C + +

All C + + books have been explicitly proposed, do not use Goto, so as not to cause confusion in the process of the program, so that the understanding and debugging procedures have difficulties.

But what do we do with a scenario like this: whether the program executes successfully or not, it executes some resource release statements, which are pretty much the finally statements in Java. There is no finally support in C + +, even if you use try catch, the resource release needs to be written two times, executed successfully once, and catch once. Using Goto can be a very elegant implementation of finally.

void Fun () {    INT32 rc=OK;        RC=dosomething ();    Check (RC);    //    if (rc!=ok) goto error; Done     :      //cast resource, do is must execute statement quick        return  RC;      Error:        goto done ;}
