Write your reply.

assistant: If you're working with a Pentium processor this isn't exactly right
True, almost all floating point instructions do not pair ( you can only pair
FXCH with stuff like FADD,FSUB,FMUL etc.. ) but instructions can overlap,
this means that the next instruction can be started while the first is
still being executed.
example :
	FADD ST(1),ST(0) cycle 1-3
	FADD ST(2),ST(0) cycle 2-4
	FADD ST(3),ST(0) cycle 3-5
	FADD ST(4),ST(0) cycle 4-6
Ofcourse to get the most out of this your code must follow a few rules,( the
second instruction does not overlap if it needs the result of the first, a
FMUL can't start the clockcycle after another FMUL, etc... )
This means the number of FLOPS (for the Pentium processor) depends a lot on
how you write your code / the intelligence of your compiler
and so to simply divide the Mhz by the number of clockcycles of a single
floating point instruction takes, will you not give you a very meaningfull
result.

Write your reply.

assistant: Yes, but the result may not be what you want. You could declare the
array as a static member. Then you run into the problem that only a
single copy of array exists for all instances of the class.
Another alternative to reduce stack usage would be to allocate array
dynamically using new. Now data space for array comes from the heap, not
the stack.
class A {
   private:
      int *array;
   public:
      A(int n = 100) { array = new int[n]; }
      ~A()  { delete [] array; }
};
Correct. Since b[] is a static array, the data members for all 50
objects are in data memory, not on the stack.

Write your reply.

assistant: Neil Heller wrote in a message to All:
I think the overhead involved in maintaining folded values does not outweight
the troubles, especially when floating values are involved (like $15.6). In
cases where a very large number of small values is used it might be
worthwile, but I suppose you'd better use integers in that case as they will
certainly be faster and smaller.
AFAIK, A number of compilers have a BCD class (Borland, IBM). I'd start
searching the internet for an implementation if I need one and my compiler
hasn't one. The CUG (C Users Group) might be another source to check. Finally
SNIPPETS might have an implementation.
In C you would need a different syntax to use the BCDs. In C++ you can make
your class 'part of the language' by implementing the correct functions.
The actual algorithms however would be the same in both languages. You can
build a C++ class from a C library implementing the necessary operations if
you want (This makes it probably more maintainable if the code is used in C
and in C++ projects, but it might introduce some overhead in the C++
sion).

assistant: Herbert Bushong wrote in a message to Joshua Boehme:
This can result from using inlined constructors. I had a piece of code with
this error which had to be split up in three parts. After outlining all ctors
for the classes used in the module it again fitted in one module. This
happened in the function of the class which was responsible for creating a
graphical representation of the instance, which involved creating a large
amount of graphical primitives. (There were more than 100 instances
nvolved).
The total application shrinked (shrunk?) about 500Kb (total size was 5Mb).
I have to admit this cause is unlikely in your case, but if size is a
problem, do not use inlined ctors or dtors as they can become very big due to
added code by the compiler.

Write your reply.

assistant: struct Thing {
  int  Across, Down;
  char Thingchar;
}
Thing You = { 1, 1, '\@' };  // In C++, the struct is not required
You don't need the dummy. You're passing a pointer so you must
dereference it properly. You cannot use the '.' operator directly on a
pointer. You could do (*T).Across, etc. but C/C++ provides an operator
to do this more smoothly. T->Across.
void ShowThing(Thing *T)  // Return unnecessary so use void
{                         // Also, in C++ struct not required
  gotoxy(T->Across, T->Down);  // Use -> operator to dereference pointer
  putch(T->ThingChar);
}
Now that's better!
Ah, but the idiosyncracies are where the magic lies. As a matter of
fact, you should make ShowThing a member of Thing, this being C++ and
all. Also add a constructor to initialize a Thing. That makes life even
easier:
struct Thing {
  int  Across, Down;
  char ThingChar;
  // Constructor
  Thing(int a, int d, char c) { Across = a; Down = d; ThingChar = c; }
  // ShowThing() member
  void ShowThing(void) { gotoxy(Across, Down); putch(ThingChar); }
};
int main(void)
{
   Thing You(1, 1, '\@');
   You.ShowThing();
   return 0;
}

assistant: Hi Jerry,
   Moved this from the C echo.
Ok, I just bypassed the problem using a class. Here's the sample code I
mentioned in the C echo:
===========test1.cpp===============
#include <iostream.h>
class test
{
  private:
    int x;
  public:
    test(){x=0;}
    test& operator++(int){x++; return *this;};
    friend ostream& operator<<(ostream& os, test& t);
};
ostream& operator<<(ostream& os, test& t){os << t.x; return os;};
int main(int, char *[])
{
  test tst;
  cout << "x = " << tst << endl;
  tst++;
  cout << "x = " << tst << endl;
  (tst++)++;
  cout << "x = " << tst << endl;
  tst++++;
  cout << "x = " << tst << endl;
  return 0;
}
==========end test1.cpp=============
It compiled and worked correctly. The output was:
x = 0
x = 1
x = 3
x = 5
So it CAN be done, just not in C or C/C++ with the built-in types.
