Please post the smallest piece of code which shows this behaviour, only then can
we try to help you. Without seeing your code there's no use in guessing what may
be wrong.

google for pop3 email C/C++ libraries and how to use them
if you can access your yahoo email via imap, you can also google for imap C/C++

Hi Everyone,

I am trying to break down the byte into small pieces of bits. Here is what I
want to do. open for any suggestions.

typedef struct
{
   unsigned char a : 2;
   unsigned char b : 3;
   unsigned char c : 3;
} test_byte;

int main()
{
  unsigned char n1 = 8;
  test_byte tb1;

  tb1 = *(test_byte *)n1;

}
output:
tb1.a = bit0 bit1
tb1.b = bit2 bit3 bit4
tb1.c = bit5 bit6 bit7

this is what I am trying to do any suggestions please welcome.

Thanks....

Don't use structs - it's overkill. And potentially relying on
behaviour that may not be portable.

int bits01(unsigned char c){
    return (c & 0x03);
}

int bits234(unsigned char c){
    return (c >> 2) & 0x07;
}

int bits 567(unsigned char c){
    return (c >> 5) & 0x07;
}

I suggest you change the names of the functions to more accurately
represent what those bit groupings actually represent.

I know this code has more to do with assembly than C but that's why
I am having trouble understanding it.  I am not sure why the code
pushes SI twice and why push DI when it's not used. I need to know how does C
function know how to return the average so that assembly can retrieve it.

I think i need to fully understand this before i work on a program of my own
with mixed mode.


/* An example to illustrate  C function  -> assembly -> a C function.
      This program calls the assembly language procedure in file MARKS_A.ASM.
      The program outputs min,  max, and rounded average of two marks. */

  #include <stdio.h>
  int main(void)
  {      int mark1,mark2, min, max, av;
 	 int find_avg(int, int);
        	 extern  void stats(int, int, int*, int*, int*);
        	 scanf("%d%d",&mark1,&mark2);
        	 stats(mark1,mark2, &min, &max, &av);
	 printf("Min = %d, Max = %d, Av = %d\n", min, max, av);
        	 return 0;   }


   /*********************************************************
      * Returns the rounded average required by the assembly
     * procedure STATS in file MARKS_A.ASM.*/

	 int find_avg(int total, int number)     {
        	 return((int)((double)total/number + 0.5)); }


;---------------------------------------------------------­
; Assembly program example to show call to a C function.
; This procedure receives a marks array and class size
; and returns minimum, maximum, and rounded average marks.
;---------------------------------------------------------­
   .MODEL SMALL
  EXTRN _find_avg:PROC
  .CODE
   PUBLIC _stats
   _stats PROC
          	 push  BP
          	 mov  BP,SP
           	 push  SI
           	 push  DI


         	 mov   AX,[BP+4]            ; AX := mark1
         	 mov   DX,[BP+6]           ; DX := mark2
	         cmp   AX,DX 	 ; put min into AX and max into DX
               	 jl      next
               	 xchg   AX,DX
    next:
:         mov  SI,AX          	 ; SI gets sum
	         add  SI,DX

         	 mov   BX,[BP+8]   	 ; return minimum
          	 mov   [BX],AX
           	 mov   BX,[BP+10]   	 ; return maximum
          	 mov   [BX],DX

		 ; now call find_avg C function to compute average

                 mov    AX,2 		 ;push number of marks
                 push   AX
	         push   SI 		 ;push sum of marks
          	 call   _find_avg    	 ; returns average in AX
           	 add   SP,4         	 ; clear stack
          	 mov   BX,[BP+12]  		 ; return average
          	 mov   [BX],AX
           	 pop   DI
          	 pop   SI
           	 pop   BP
          	 ret 	  	 ; NOTE calling program clears stack
_stats       ENDP
	 END

Saving and restoring BP,SI,DI is probably a formality included whether they
happen to be used or not (at least by the author of this program). Those are the
only registers required to be preserved.

The second push for SI that appears in:

push  AX
push  SI 	 ;push sum of marks
call  _find_avg  ; returns average in AX
add   SP,4        ; clear stack

is only to set up the two parameters (total,number) in that order on the stack
for the _find_avg subroutine. SI is the total.

Hi Folks,

I need some help in XOR the bits in a byte 8 bits.

flag bit = b1 xor b2 xor b3 xor b4 xor b5 xor b6 xor b7 xor b8

I want to do this with minimal operations in C.

thanks.

What you're after appears to be functionally equivalent to working out
the parity of a byte:

Hello Group!

I was wondering what the breakdown of the group members is regarding using c
versus c++?
Just a ballpark figure.   c/c++.     50/50?      90/10?     10/90?    1/99?  
99/1?

I am learning c++.  strictly recreational.  I am most familiar with BASIC, but
figured it's time to  learn something used in this century.  I am using "C++
Primer Plus" (Stephen Prata) as a text.

I also am a devoted Mac person, but am starting to think that c++ is not a good
choice for the Mac.

You appear to be missing the group that uses both.

I'm sure modern versions of FruitOS come with gcc.

I do a lot of C, I do no C++.

Mac -> native is mostly Objective-C I think.
I imagine that if Apple's compiler doesn't handle C, that gcc would be
available for OSX.

http://developer.apple.com/mac/library/documentation/cocoa/Conceptual/ObjectiveC\
/Introduction/introObjectiveC.html
The Objective-C language is a simple computer language designed to
enable sophisticated object-oriented programming. Objective-C is defined
as a small but powerful set of extensions to the standard ANSI C
language. Its additions to C are mostly based on Smalltalk, one of the
first object-oriented programming languages. Objective-C is designed to
give C full object-oriented programming capabilities, and to do so in a
simple and straightforward way.

I have a programming project that i need help with. I have to do the C  program
then dram the flowchart. I have already done the program but i have problem
doing the flowchart can someone help me

On some groups you can create a poll but I don't see how to do it here.  Right
now I use C for embedded and C++ and C# (these 2 for consumer apps) and VB for
my own utilities.

Actually, the example you provided does show both.
c/c++ -> 50/50 -> uses c 50% of the time and c++ 50% of the time
c/c++ -> 90/10 ->        90%                     10%
c/c++ -> 10/90 ->        10%                     90%

Hi,

I am not able to understand the output of the following:

unsigned char x;
x = 300;
printf("%d",x);

int x,y;
x = 5;
y = 10;
printf("%d\t%d\t%d\t%d\t",x++,y++,++x,++y);

Understandable, since what you're doing isn't defined, and you
shouldn't do it in C or C++.

You're basically modifying both x and y twice between sequence points,
which doesn't have any 'defined' behaviour.

Sad to say these are generally just spams. I tend to be wary of any who ignore
the lists topics lie that. You're more likely to end up with even more spam
by replying to it and prob more virii sent your way. You'll note there's no
mention of the company looking to hire. That's so you can't check up on it

Sorry that I haven't seen this stupid spam message early enough.
I have removed this person from the forum and will continue to do so in the
future.

These spam posts are the reason why I've set every new member of this board to
Moderated status. Sad to see that sometimes I miss one or the other. Sorry for
that.

I have the following assignment in my one class for the week and a major part of

and choose the best one.

The project is due next Tuesday.  Any assistance will be highly appreciated.

Thank You
