int get(){...} void bar(int *i){...} and often we call function this way bar( get() ); but no work this way. how to solve the proble? 1 solution : int *get(){...} or void bar(int i){...} but usually changing exsited function is not allowed. so Just only a solution ? : int i = get();//use temp var bar(&i); are there something solution?

The following should work:
bar( &(get()) );

It takes the references of the result of the evaluation between the '( )'.
But in most situations I find the extra temporary variable easier to read. I suppose that the variable will be optimized out anyway, if you're worried about that (not that you should..).

I already do this way
but runtime error.
I think temp variable is unavailable when parameter passed.

I do bar( &(get()) ); before just runtime error
now c2102 error happen.
