Your program is a mess, had no error checking and crashed nonstop. That's why strtok is considered "evil" -- if you don't bother checking, bad things will happen. But a little checking makes it fine.
Nearly every line ended up commented out and replaced, I had to rewrite it instead.
Hi
i have the following structure
struct S
{
char Mod_num;
char val;
char chr_nm_cd;
}
I am reading a 2GB file and inserting into the structure and writing into a vector.
I feel like only vector will be a right option. I tried with multimap but it is memory intensive and hence i... (1 Reply)
Can someone tell me how to do this?
Just a thought that entered my mind when learning about structs.
First thought was:
struct one
{
struct two;
}
struct two
{
three;
}
one->two->three
would this be how you would access "three"? (1 Reply)
I modified some code I found on Wikipedia concerning maps to see if it would work before applying it to a project I'm working on that has a similar idea.
What I would want is for a user to be able to enter sentences and then be able to distinguish how many times a the person entered a word in a... (4 Replies)
Hi, I've used the following way to set ssh public key authentication and it is working fine on Solaris 10, RedHat Linux and SuSE Linux servers without any problem. But I got error 'Server refused our key' on Solaris 8 system. Solaris 8 uses SSH2 too. Why? Please help. Thanks.

Hi,
I have received an application that stores some properties in a file. The existing struct looks like this:
struct TData
{
UINT uSizeIncludingStrings;
// copy of Telnet data struct
UINT uSize;
// basic properties:
TCHAR szHost; //defined in Sshconfig
UINT iPortNr;
TCHAR... (2 Replies)
Hi all, from my understanding I understand that I can use array in this manner.
struct test
{
int a;
int b;
int c;
};
test testing; //creating an array with the structer type
testing.a=1;
testing.b=2;
testing.c=3;
If I'm not wrong we can use array in this manner,... (12 Replies)
hello guys.
i'm new to c++. i've problem using two dimensional vector.
i've a project of making conway's game of life. this is the code that i have made so far.
my problem is how can i give a two dimensional vector through main.
glider.vec1 = vec; is not correct way to give a two... (2 Replies)
In AWK
For 3 individual vectors of the form:
-2.772 -9.341 -2.857
-5.140 -6.597 -1.823
-2.730 -5.615 1.159
I would like to write a script that parses line by line to (i) normalise, (ii) divide by the norm for *each* vector.
I.e.
sqrt(-2.772^2 + -9.341^2 + -2.857^2)=10.154

wcstok
WCSTOK(3) Linux Programmer's Manual WCSTOK(3)NAME
wcstok - split wide-character string into tokens
SYNOPSIS
#include <wchar.h>
wchar_t *wcstok(wchar_t *wcs, const wchar_t *delim, wchar_t **ptr);
DESCRIPTION
The wcstok() function is the wide-character equivalent of the strtok(3) function, with an added argument to make it multithread-safe. It
can be used to split a wide-character string wcs into tokens, where a token is defined as a substring not containing any wide-characters
from delim.
The search starts at wcs, if wcs is not NULL, or at *ptr, if wcs is NULL. First, any delimiter wide-characters are skipped, that is, the
pointer is advanced beyond any wide-characters which occur in delim. If the end of the wide-character string is now reached, wcstok()
returns NULL, to indicate that no tokens were found, and stores an appropriate value in *ptr, so that subsequent calls to wcstok() will
continue to return NULL. Otherwise, the wcstok() function recognizes the beginning of a token and returns a pointer to it, but before
doing that, it zero-terminates the token by replacing the next wide-character which occurs in delim with a L'
