removing white space from a char[] (C)

Euphoric Nightmare · 2005-09-07 04:20:35

Is there a function from the standard c library to do that for me?

STiAT · 2005-09-07 09:07:09

standard c or c++?

in c++:

string::iterator it=temp.end();
temp.erase(remove(temp.begin(),temp.end(),' '),it);

to remove whitespaces of a string.

In c i'd rather use strtok:

char *as,*df;
as = strtok(str, " ");
while ((df = strtok(NULL, " ") != NULL)
{
    strcat (as,df)
    memset (df, 0, strlen (df));
}

Lg,
STi

Nifty trick. Thanks for the advice

better to run a python instance and run string.trim()

No, you'll be an efficient hacker...

Actually I was going to try to learn some python...I don't know what happened...

Dusty · 2005-09-08 13:03:28

Got bogged down in C! :-D

I don't understand when people who can program in one language say "I was going to learn Python". Python doesn't have to be learned. If you understand structured and/or object oriented programming, you know Python already; its just the natural syntax you would use.

I like Java.

Euphoric Nightmare · 2005-09-08 14:01:18

Yeah, thats right. I was going to learn c and python at the same time, but then i got so excited about c...well...

I can see what your saying about the python syntax...its very easy to read.

I haven't seen you say something like that in a very long time.

But trim won't removing it from inside the string... you want replace(' ','');

#include <boost/string_algo/trim.hpp>
std::string s = "   i hate whitespace       ";
boost::trim(s);

s = "~~~~~some other crap~~~~~";
boost::trim_if(s, std::equals<char>('~'));

Yeah, I'm a troll. :-D

i haven't seen that trim thing dusty is talking about but replace() fix stuff like this,

>>> g = "     arch       linux     "
>>> g = g.replace(" ", "")
>>> print g
archlinux

Dusty · 2005-09-08 17:55:59

How embarrassing.

trim() is java syntax. Under python I was thinking of strip. It works as so:

>>> g = "     arch       linux     "
>>> g.strip()
'arch       linux'

=>"            xersex2  is very cool ".tr(" ", "")
=>"xersex2isverycool"

whatlanguageisthatgreen?

Dusty · 2005-09-10 21:15:41

knowing Mr. Green, its probably lua, but could theoretically be ruby...

Or he made it up. :-D

Dusty

xerxes2 · 2005-09-10 21:19:41

i tried lua and it didn't work

does'nt ruby work in a terminal?

dust · 2005-09-11 01:55:49

looks like ruby

xerxes2 · 2005-09-11 17:36:00

a little bird whispered in my ear that rubys terminal is called 'irb'
