Can we specify variable field width in a scanf() format string? If possible how?

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()
