Question :
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().
