sscanf shortens it by 20 lines, you can just tell it "lines should like this" and it'll sort it into the arguments you asked for and tell you whether it could. It even protects against overflows if you tell it to (%20s, so it doesn't overrun a 21-char buffer).
This is what bugs me most about the 'scanf is dangerous, strtok is dangerous' camp. As opposed to what, hand-writing your own unchecked ad-hoc string parser? At least C has a parser.

Those are only concerns of advanced programmers. I can't predict the situations even you pointed it out.
BTW, the last version has a bug if there is a blank line in the input file....(No worry, I'll try to fix it myself.)
The biggest point for me is from the lines:
I did not know this way to assign a map_pair so much simply.
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

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)
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)
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, 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.

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)
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)
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)
