Summary:
In Microsoft C versions 5.0, 5.1, 6.0, 6.0a, 6.0ax, and C/C++ version
7.0, the scanf() run-time library function allows the specification of
the width that you would like to read in from the input device. Some
examples of this width formatting are as follows:
scanf ("%10s", buffer); /* read ten chars into buffer[] */
scanf ("%5d", &i); /* read five digits of a number into i */
When using width parameters in the format, the first n digits are read
into the address specified.
More Information:
When used with a character string, the width parameter performs as
follows:
char buffer[15];
scanf ("%10s", buffer);
The first 10 characters are read, and a null terminator ('\0') is
added to the end of the string.
When used with an integer or float, scanf() always reads the first n
characters (including decimal if in a float) specified with the width
format. Entering invalid characters (for example, a decimal in an
integer, or any alphabetic character) causes the termination and
failure of the read.
