I'm going to have a nightmare about that regex, I just know it. --lee

Ah, that's possible. --blahedo

Did you give a phone number when you registered to vote? In-district polls are much more likely to be based on voter files. (As opposed to national polls, where a call on your cell is probably due to Random Digit Dialing). Also, it's really reassuring that I'm not the only one who gets absurdly excited about getting polled. --Anna Novikova

I remember Mike fondly from my days at Powerhouse Gym in Schaumburg, Illinois. I relocated to California in 2000 and years later I was searching for old friends online and came across the sad news. Mike was always fun to talk to, I admired his dedication and I really liked him. He is still missed among his many friends at that gym that have long since gone their separate ways. --Rob Eckaus

Good find and thanks for translating. She's looking for a 22 year old rich guy with big feet. Hmm. --Andrew E

They are validating the username against several validation rules. One of them is 'eeUserName', which must match the following regex: ^(?=.*[0-9@_./-])(?=.*[a-zA-Z])([a-zA-Z0-9@_./-]){6,74}$ See if you can make heads or tails of it. I can't. --Bob

When I said "no warnings, no errors", I meant by default. If I compile -Wall (or -Wsign-compare) then yes, it does give a warning; but it gives that warning even if you are writing the correct version of the code! If you count up from zero and make the comparison "while (pennies < names.length())" you get precisely the same warning. So this is not at all helpful from a pedagogy perspective.

The standard is written that this kind of type conversion is normally silent, and the real problem here is that it's not even clear what names.length() returns (signed/unsigned), it's slightly difficult to find that out (and nearly impossible if you don't already have some idea of the potential problem), and at the point in a CS1 course where you might be doing this, the students may not even know the difference between signed and unsigned!

C++ has its place in the world. Intro CS courses are not that place.

"[...] the negative number is silently converted into a very large positive number. No warnings, no errors." What are you talking about? "warning: comparison between signed and unsigned integer expressions [-Wsign-compare]". But yes, I do see your point. --Johannes

C and C++ are rather low level, so they definitely need a little bit more experience, but bad code can be written in any language. I would rather choose Python, Ruby or Lua as an introductory language. --Studiosi
