what is "streamsize" and "width(n)"?

Hello,

I read the specification of width(n) and it says this function allows
me to pad on the left to the stream's width, and this width is
"streamsize". What is streamsize exactly? Is it measured in the
number of chars or something?

Thanks,
Jess

I tried it on an example

cout.width(10);
cout << "hello" << endl;

Then I noticed there are only 5 characters padded on the left of
"hello". Why is it not 10?

Thanks,
Jess

value in a 'field' of width 10, 5 spaces plus 5 for "hello" equals 10.
