Answer:
All field widths are variable with scanf(). You can specify a maximum field width for a given
field by placing an integer value between the
% and the field type specifier. (e.g. %64s). Such a
specifier will still accept a narrower field width. The one exception is %#c (where # is an integer). This reads EXACTLY # characters, and it is
the only way to specify a fixed field width with scanf().Related Articles:
