Do you even 'break' bro?!

So...I havent been on here in a while, but I cant seem to find the wall of shame so I thought here would do :P While going through our current framework I came across a module written by one of our senior devs, who apparently doesnt know what a break is, here is an example of what he does :
for (var i = 0;i < myArray.length; i++) {
if (conditionIsMet) {
i = myArray.length;
}
}I gave him the benefit of the doubt and thought that maybe he was using i somewhere else, but he wasn't. Anyways, just a little laugh...Has anyone else found any gems like this??

In school I was taught that it was very wrong to break out of a loop. It wasn't just taught, there were 2 commandments students had to live by. One had to do with goto , the other was "You never break from a loop". You could get points off your project for that, or possibly a bad grade. What you posted is exactly what I learned, however with some instructors you could get away with adding a compound condition to the for loop. Of coarse in the real world you can break :cool:
If it moves, compile it

In school we learned never ever to use break, continue or goto (only exception is break in switch statements). If we had to break we were told to develop a construct like you mention here. Similar for return statements (only allowed for each method). This one however I support. You were downgraded if you didn't obey this rule.

You're forgetting the old maxim: "Those who can, do; those who can't, teach" There is nowhere where this is more apposite than in university computer education. :sigh: If you wish proof of this, just visit QA...:suss: (My apologies to any good teachers out there: you do know you are in a teeny, tiny minority, right?)

I prefer to avoid a
breakin aforloop, but that's the worst way to do it. :sigh: -

Now I realize that what was taught (and is been too) is sheer elephanting nonsense X| X| X|

Wow, that's crazy. Not using
breakis wasteful, if you know you're done with the loop you should just get out of it, and it's not like it's unclear where it goes.continueI can kind of get, you could just reorganize your code in most cases (since probably 99.99% of the time it's already in a condition, and that condition could be flipped). It really sounds like your teachers heard "don't use goto" and decided that included any instruction that directly created a jump :doh: (minus structures like conditionals and loops) -

I am speculating that those who were taught to never use break in school had a prof. (who are we kidding, an adjust faculty member) who grew up with VB where breaks and exits litter the landscape like reflective markers on a roadway. Avoiding spaghetti logic is important, avoiding breaks not so much. I had a great VB6 example of how not to use breaks but I can't find it. Rule of thumb 1 break per loop is ok, more than 1 is not.

And did your instructors explain why it was unwise to use a
goto? (Was Dijkstra's paper ever discussed in class?) /raviMy new year resolution: 2048 x 1536 Home | Articles | My .NET bits | Freeware ravib(at)ravib(dot)com

What the actual elephant. A for loop with a conditional break is a standard idiom for finding things in collections ... never mind permitted, it's a standard pattern!
Breaking out of aforloop is a code smell. (What's presented is even worse.) Maybe you don't want aforloop at all. Or, quite possibly, you just need another condition.for ( int i = 0 ; i < MaxCols && i < dr.FieldCount ; i++ ) -

Or, quite possibly, you just need another condition.for ( int i = 0 ; i < MaxCols && i < dr.FieldCount ; i++ )I personally prefer using the method you suggested as it is the cleanest looking and preserves the loop invariant. Breaking half way through the loop means you don't properly finish the iteration and raises the question of why did you actually start the next iteration if there was no need to do it. Its like going to the store to get a loaf of bread and then realizing half way that you already have bread at home and then turning back
