Another weird thing. Why is J's value 1 instead of 0 here??



(gdb) b main
Breakpoint 1 at 0x100000ad4: file month_reminder.c, line 11.
(gdb) r
Starting program: /Users/javaxtra/Desktop/MY/c...

Thank you again for all kind response.
My question is, yes I see that i is being incremented and points to last point position when it reads all input, so at the end, it's pointing to last position...

Just one more question, I am failing to see where the value 'i' (for which is being return) is being used for.. ?



int read_line(char str[], int n )
{
char ch;
int i = 0;

...

@anduril462,

Thank you for your explanation. Very detailed. I understood perfectly.

Here's the code I am studying from "modern day c programming"



#include <string.h>

#define MAX_REMIND 50
#define MSG_LEN 60

int read_line(char str[], int n);

just in case any other newbie like me wanted to see the steps



#include <stdio.h>

#define TRUE 1
#define FALSE 0

typedef int Bool;

You are right.

thank you!!

Enter a number: 123
digit is 3
n is 123
n is 12 after division
digit is 2
n is 12

Hi, I am testing a below from book " C : a modern approach"..

I don't understand why this program is not working ... when i put 123, it digit_seen should still be false(intialized all w/ 0).. but...

Hi, thanks for replying on this issue.

I guess I have a problem understanding the syntax of it.
Wouldn't Ethernet_Frame pointer be --> *Ethernet_Frame ?

but instead, I have Ethernet_Frame* ...

ethdr = (ETHERNET_FRAME*)&tmp[0];

I thought pointer (whether declearing or referencing it), * should be on left side of the word.

One of the code I was studying, I saw code like above where *...

that's what i don't understand.
I have gone through other included headers and did not see the __THROW defined anywhere.






#ifndef _SYS_IOCTL_H
#define _SYS_IOCTL_H 1

extern int ioctl (int __fd, unsigned long int __request, ...) __THROW;

how does one read above?

I was thinking global int type function name ioctl has these (....).. but what is
__THROW...

can someone provide me w/ great tutorial or link that explains the relationship between multi dimensional array and pointer?

I can see that char reminders[MSG_LEN+3] is one string vs char...

thanks guys,

I certainly now understand what those loops are doing.
one more thing however, I really don't understand why it was necessary for multi dimensional array to be need for

11 ...

thanks guys, I am gonna digest this bit and try few more things and get back to you guys..

thank you once again!!

Hello everybody,

I have been reading C programming "a modern approach" and I must say this has been my best c book(I am a very very newbie)..
Anyway, below example from that book has me bit lost...

thank you!!!!

my gosh, yes thank you so much.



(int)(cp-in_line));


I just have one more question..

why was there a need to subtract in_line from cp ?

Hi, here it is.



root@userA-laptop:/sc/c# cat cha_handle.c
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#define LINELNG 100 /* max length of input line */

that didn't work..

anything else?

Hello, I am just going over tutorial on line and working on this character handling program from on line tutorial.

First of all, I just copy the program but it doesn't compile.
It complains that...

so far this is working fine for me..



#include <stdio.h>
#include <string.h>

main( int argc, char *argv[] )
{
//char filename[29];

my bad,

of course only below code would product 5.. I am still trying to see what everyone was talking about earlier.. will get back to you. thanks



#include <stdio.h>

main()
{

sorry, Quzah, but I just tried your code and it actually printed 5.. ?



[root@Xclient c]# cat variable_print.c
#include <stdio.h>

main()
{
int x = 5;

cyberfish, I certainly understand and appreciate your concern.

Sometimes, I don't understand such simple as

system("command", "arg1", "arg2"); where arg1 or arg2 can be variables..
in perl...
