Post #109,145 by gdaustin 7/11/03 12:02:20 AM Reply	Re: okies yankout spaces I was thinking along the same lines. Isn't there a regular expression that could do that in 1 line? Something in perl? Or a call to grep with piped output?
Post #109,147 by orion 7/11/03 12:06:01 AM Reply	In Visual BASIC 6.0 and above there was a replace command for strings. strName = Replace(strName," ", "") Does C++ have a replace command like that?

Post #109,333 by tuberculosis 7/11/03 7:08:42 PM Reply	Or maybe (string copyWithout: $ ) This is sort of a fun little exercise actually - I don't think in Smalltalk enough. Smalltalk is dangerous. It is a drug. My advice to you would be don't try it; it could ruin your life. Once you take the time to learn it (to REALLY learn it) you will see that there is nothing out there (yet) to touch it. Of course, like all drugs, how dangerous it is depends on your character. It may be that once you've got to this stage you'll find it difficult (if not impossible) to "go back" to other languages and, if you are forced to, you might become an embittered character constantly muttering ascerbic comments under your breath. Who knows, you may even have to quit the software industry altogether because nothing else lives up to your new expectations. --AndyBower

Post #109,290 by gdaustin 7/11/03 2:13:16 PM Reply	You're looking for "best algorithm" I was looking for compact code, quick implementation. Sadly, a lot of the work I have to do is done in a hurry, so the customer doesn't care if it's a bubble sort or quick/merge/insert sort unless the data set is really large. Also, I work with databases a lot, so when someone wants it sorted, I ORDER BY on the SQL and it's done. DB2 SQL is my best language. Java is probably next. I haven't looked for the "best algorithm" since I worked at SABRE, where we had lots of time (usually at least 2 quarters) to implement something. Glen Austin
