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().

Summarize effective communication strategies in organizational hierarchies, and review the role and relevance of the organizational grapevine Some companies try to encourage communication through workspace design, as well as through Web-based communication channels. some executives also meet directly with employees, such as through management by walking around (MBWA) and town hall meetings, to facilitate communication across the organization.
