What does this line of code do?? (easy)

**Wak** · Jul 15th, 2001, 04:39 AM

I'm not sure what this does, can anyone help?

cxCaps and cxChar are both integers

Code:

cxCaps = (tm.tmPitchAndFamily & 1 ? 3 : 2) * cxChar / 2;

It's mostly '& 1 ? 3 : 2)' That I don't know the meaning of.

Thanx

Where did you get this code. The absolutely same question was posted by abdul a while ago. Here is the link

I got it from a bloke called Charles Petzold.

Would

Code:

cxCaps = (tm.tmPitchAndFamily & 1 ? 3 : 2) * cxChar / 2;

and

Code:

cxCaps = (tm.tmPitchAndFamily ? 3 : 2) * cxChar / 2;

Do the same thing then?

Whoops, I just stared blankly into the screen for 1/2 an hour and it hit me.

Code:

cxCaps = (tm.tmPitchAndFamily & 1 ? 3 : 2) * cxChar / 2;

Is the same as

Code:

cxCaps = ((!tm.tmPitchAndFamily & 0) ? 3 : 2) * cxChar / 2;

I'm not the best @ C++ yet, sorry

Yes, I am reading the same book. Is it programming windows 95 or windows 98?

**Wak** · Jul 15th, 2001, 04:17 PM

I dunno, the title is Programming Windows 5th Edition by Charles Petzold

**abdul** · Jul 15th, 2001, 08:55 PM

The author is giving almost the same examples in his window s programming books.

I am reading "Programming Windows 95"

I've heard the term 'a lazy programmer is a good programmer ' used, but plz. That refers to programming only.

Not book writing.

Does it matter?

Ternary form is one of the easiest-confused operators - took me a while to learn it (I was still looking up which way round the true and false values went until about a month ago

)
