unfortune me, i get trouble in my writing...please help me to solve my problem.

1. in C and D has same way to declare variable right?. but what the
differencies between C and D in variable declaration?. does identifiers
influence the way of declare variabel between D and C?.

2. what do you think about perfomance between C and D?. do D better than C?.

3.does D use system memory bigger than C?.

-it seem that i doing for an interview, right?hehehehehe-
thanks before....GBU

Read for example http://www.digitalmars.com/d/statement.html (Declaration
statement), and http://www.digitalmars.com/d/attribute.html (attributes and
type inference). There are other differences too.

 
 2. what do you think about perfomance between C and D?. do D better than
 C?.

You can't really benchmark languages.

 
 3.does D use system memory bigger than C?.

Current D implementations have bigger memory footprint than C implementation
by default.

 1.  in C and D has same way to declare variable right?.  but what
 the differencies between C and D in variable declaration?.  does
 identifiers influence the way of declare variabel between D and C?.

<snip>

The basic syntax is the same, but there's a handful of differences:

(a) declaring pointers:

    int* qwert, yuiop;

declares both qwert and yuiop to be pointers in D.

(b) array declaration notation:

    int[42] asdfg;

whereas C requires

    int asdfg[42];

(c) function pointer notation:

    int function(float) hjkl;

compared to the more awkward C notation

    int (*hjkl)(float);

(d) D can do a lot more than C can do here.
