C++: stripping '/' char from istream

[wxjunkie]

In C++... What's the easiest way to strip a "slash" out of an input stream so I can just work with what's left?

 

[Nothinman]

I guess you mean pull them all out and replace with nothing?

So you take /usr/blah/blah and convert it to usrblahblah before working with it?

 

[wxjunkie]

Yea that's exactly what I need to do

http://www.cppreference.com/cppstring.html should help
I don't know of a better way than doing find('/', 0) w/ replace(index, 1, '') in a loop until find returns npos.

How about simply initializing a temporary buffer, then use a for loop to go through each character in the stream. If not slash character, put it in temp buffer and increment buffer length, else ignore. At the end, null-terminate the buffer.

Crude, but works.

Depends on what kind of string you are using. The old string or the STL string.

Once you learn the STL strings they are a lot more flexible and easier to do stuff like this with.

#include <string>
using namespace std;

string dir = "/usr/local/bin";
for (string::iterator s = dir.begin(); s != dir.end(); ) {
if (s == '/')
s.erase();
else
++s;
}

I'm about 95% sure that's the way I did it. My source is at the office so if that doesn't work for you I'll doublecheck.

EDIT: Sorry I thought you said string instead of stream.
