Question

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

Answer 1

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().
