urgent help needed

[Gohar]

Any one please send me the C++ code for arithmatic calculator using
linked lists
Which performs addition ,subtraction,mu ltiplication,di vision and
modulus(using operator overloading).
i need it badly,urgently before monday
please send it to my mail address
i shall be thankful ,
Regards

Try the TDatetimepicker and pick a date three weeks ago.
That should give you plenty of time.
O well, too late now....

So you are:
- too lazy to do your homework yourself
- too computer-illiterate to do an internet search for a solution
- too ignorant even to know the difference between C++ and Pascal.

Duuuh!

and you love feeding the trolls :(

I have no idea what such code might look like in C++ and my Delphi version
doesn't support operator overloading. But the guts of what you ask for
might look something like the following in D5.
Type
pStackRec = ^ tStackRec;
tStackRec = record
rValue : double;
rLink : pStackRec;
end;
tCalcOp = (add, subtract, multiply, divide, modulo);

var CalcStack : pStackRec = nil;

procedure PushStack (val : double);

var p : pStackRec;

begin
New (p);
p^.rLink := CalcStack;
CalcStack := p;
p^.rValue := val;
end;

function PopStack : double;

var p : pStackRec;

begin
if CalcStack <> nil
then result := CalcStack.rValu e
else raise Exception.Creat e ('Stack underflow');
p := CalcStack;
CalcStack := CalcStack^.rLin k;
Dispose (p);
end;

function StackCalc (op : tCalcOp) : double;

var p : pStackRec;

begin
if CalcStack = nil
then raise Exception.Creat e ('Emtpy Stack');
p := CalcStack;
result := 0.0;
if op in [add .. modulo]
then begin // two operands required
CalcStack := CalcStack^.rLin k;
if CalcStack = nil
then raise Exception.Creat e ('Missing operand');
case op of
add : result := CalcStack^.rVal ue + p^.rValue;
subtract : result := CalcStack^.rVal ue - p^.rValue;
multiply : result := CalcStack^.rVal ue * p^.rValue;
divide : result := CalcStack^.rVal ue / p^.rValue;
modulo : result := CalcStack^.rVal ue - ((CalcStack^.rV alue /
p^.rValue) * p^.rValue);
end;
Dispose (p);
CalcStack^.rVal ue := result;
end;
end;

Why do this the hard way.

I showed a 10 year old kid how to do this in VB and then in Delphi.

Just put some edit boxes on the form.

and some buttons - - click a button does selected task. Cheap, Simply
and educational. The kid and friends played with it for hours - to the
mothers surprise. and the kid did the coding.

No stack or anything like that - - - but it worked and was a lesson for
the kid.

but then again this sounds like a home work assignment. - - -

Because that is what was asked for.

Except that this solution cannot handle out of order evaluation, e.g. 5 + 6
* 7, with correct operator precedence. Glad the kids had fun learning
something new.

that is why you need a globel number and operator stack with a recursive
evaluation function.
done that! been there before!
