Say,

struct foo
{
int x;
double y;
/* etc. more variables defined */
short u;
char z;
} a;

Are the following true on all systems?

1) &a == &a.x
2) (&a.x < &a.y) && ( .. etc.. ) && ( &a.u < & a.z)

Are the following true if we change 'struct' to union above, on all
systems?

3) &a == &a.x
4) &a.? == &a.? where ?s can be x, y, ..., u, or z (not necessarily
equal for both ?s)

Thank you for the help.

Hello comp.lang.c

Couple of years ago I created a topic as to how I can use the function
fgets so that I can read a line of text from a source of data.

After a long time I have finally got all of my initial questions
answered accordingly.

The code below is hereby allowed to be used anybody and modified
without any legal strings attached... Simple.

#ifndef _READLINES_
#define _READLINES_

#include
//#include

#include

extern "C" short readLPostLine(FILE &rSource,char** content,int
default_length,signed int non_wanted_linefeeds);
extern "C" short readLine(FILE* pSource,char **content);
//using namespace std;

#endif

short readLPostLine(FILE &rSource,char** content,int
default_length,signed int non_wanted_linefeeds)
{
short ret=EXIT_SUCCESS;
int return_length;return_length = 0;
char* currentline;currentline...

Can you please advise me how to write two separated objects?
Sometimes, two objects have the same variable name and function name, but
they have different algorithm to perform. The C++ Compiler allows you to
create two classes. Two classes bind their own local variables and local
functions.

For example:

Class Blue
{
int a;
int b;

int Run_Color (void);
};

Class Red
{
int a;
int b;

int Run_Color (void);
};

Particularly for medium-sized (10,000 ~ 20,000 lines) programs, what
are useful strategies to design them before coding?

My strategies are:

1. Imagine what the final program would look like. Write down
options.

2. Write down many structures, such as

struct s1 {
/* contents */
};

struct s2 {
/* contents */
};

, and so on.

3. Write down many function prototypes, and classify them to different
.h files.

4. Write many macro definitions, such as "#define MAX_SIZE 100"

But having to change the original design during coding really troubles
me. Do you have any suggestions to avoid doing this?

Generally C is well suited as target language for compilers.
I use C as target language for the Seed7 compiler. This
works good. There are just some things where the
behaviour of C is undefined:

The right shift operator (>>) of C may or may not sign
extend for signed negative numbers.

Since the right shift operation of Seed7 is defined as sign
extending shift, I have to check if the C compiler does
sign extend for signed negative numbers and to use the
following algorithm:

#ifdef RSHIFT_DOES_SIGN_EXTEND
(a >> b)
#else
(a < 0 ? ~(~a >> b) : a >> b)
#endif

Does somebody know some algorithm which delivers more
performance when the C right shift does not sign extend than
(a < 0 ? ~(~a >> b) : a >> b)?

Question 3.15:

Why does the code

double degC, degF;
degC = 5 / 9 * (degF - 32);

keep giving me 0?

Would the following rearrangement solve the problem?

degC = 5 * (degF - 32) / 9;

I need to define the plancks constant 6.67 X 10 exp -34. Is it
possible to do it using #define or would you suggest using a
(static ?)const double.
