 It seems to me that it is a natural thing to do.  It seems to me
 that is is moving toward object orientation too, so I can understand
 why it is only being considered for C++.
 Still, If the language provides type that can point to any other
 type, shouldn't the language provide a way to access not only the
 data but the type that is being pointed to?   I think it would
 be a great addition that would make many more logical designs
 possible.

I must have been confused then. In Dutch we have the habit of writing

to fall into this category as well.
It's not so important anyway, as long as there can be no confusion (for
example, if you tell a beginner: "Free() is the function you need here." and
he comes back with "My linker reports _Free() is an undefined reference!").

Right, if it would only free up to the first '\0' the implementation would be

  If you declare your string as an array then you can use the sizeof()
operator to determine the number of characters that can be safely
written.  Sizeof() can only be used in this way in the same function
that the array is declared.  If you need to pass a pointer to the
string to another function, you will have to also pass the sizeof()
the array as a separate parameter.
For example, a safe string copy function:
#include <stdio.h>
#include <string.h>
char *safe_strcpy(char *dest, char *source, int len)
{
dest[--len]='\0';
return(strncpy(dest, source, len));
}
void main(void)
{
char source[11]="1234567890", string[5];
puts(safe_strcpy(string, source, sizeof(string)));
}

 no need to look for the modified command.com. even if u got it, u'll
 still get the message "Starting Windows 95" instead of getting the
 message "Starting Windoze 95". becuz the message is embedded
 in the file "io.sys" rather than in the file command.com.
 well if u want to change the message, follow the steps.
 1. get any binary file editor.
 2. reset the read only and hidden attributes of io.sys.
 3. load the file in the editor and search for the string "Starting
  Windows 95".
 4. after locating it change the message to whatever u like.
 5. take care not to overwrite the adjacent bytes as this may have
  unpredictable results.
 6. save the file.
 7. reset the file attributes to it's original value.
 8. and voila the next time u boot u will get it displayed in ur system.

 Hi John
 to represent a binary no in c there is no other way than to convert it
 into a hexadecimal no and then represent it using hexadecimal notation.
 even if ur representation is considered to be hypothetically correct the
 contents of var1 and var2 would be same i.e. 4095. to get the values of
 -32767 and 65535 u should add four more one's, to get, in all 16bits.
 now it's just 12 bits.

    I do not have the C rules on how the "internal information" on memory
    blocks are stored. It is probally one of those things that is left
    up to the compiler makers descretion.
    I guess the best thing to do if you are recieving an unknown length
    variable via a pointer is to copy it char by char into a third
    variable and then use it as the source.
    int CopyStringLessThan ( char *UnknownSource,char *MyString,int limet  )
     {
       int y=0;
       char tempstring[limet];
       while( UnknownSource[y] && y<limet )
        {
          tempstring[y]=UnknownSource[y];
          y++;
        }
       tempstring[y]='\0';
       strcopy( MyString,tempstring);
       return y;
     };
     I just can't poke a '\0' at limet because it would change the variable
     in the calling function. But at least it would return a value which
ould
     be checked. And, Since I or other would have to put in a limet there
     would be a chance of thinking about size before assignment.

Write your reply.

assistant: Hey Kurt,
    A book is certainly necessary, but not having seen the Power C book, I
can't comment. The compiler costs #24.95 here.
    Learning C depends where you are coming from, Kurt. "Strong typing" took
a bit of getting used to after BCPL and eight-bit assembler. C may well be
intuitive and natural for most of us, but a little under twenty years ago K&R
was invaluable. I wish I could say the same about Stroustrup's book. "Das
Kapital" is light reading by comparison.
    There are several tutorials on the "Black Box" CD ROM, and this is
permanently available for download from my BBS. I have absolutely no
doubt that similar facilities are available locally to anybody who wants
to learn C, and can use FidoNet(tm).
    The ANSI standard is too big and too complicated to give to
beginners. IMO it would put them right off.
Best wishes,
Bill.

assistant: Hello Bruce,
    If it's a Hudson messagebase and a Microsoft operating system I can help
with sample code. Obviously messages can be extracted on any field in the
message header. Once they are extracted you are free to do as you like with
them. It's too long to post all of it here, but it's simple straightforward
code. If you want it, I'll parcel it up for you to collect. Let me know,
please. If you modify it to run under Windows 3.1 send me back a copy. :-)
    There is one minor problem with all of these utilities. They have to be
compiled with the /Zp or /Zp1 option (or its equivalent) to ensure that
structures are packed on a single byte boundary. The sample code uses non-
standard file opening (_fsopen()) to deal with shared mode, because there
*is* no standard for file sharing other than the (Unix System V) file-locking
mechanism. Maybe that's something for the committee to get their teeth into,
but since file systems are so disparate across platforms, I'd bow out. Life's
too short. :-)
