13.6.3 Field Width (`width, setw`)

The width member function (of classes istream and ostream) sets the field width (i.e., the number of character positions in which a value should be output or the maximum number of characters that should be input) and returns the previous field width. If values output are narrower than the field width, fill characters are inserted as padding. A value wider than the designated width will not be truncated—the full number will be printed. The width function with no argument returns the current setting.

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
