Summary:
In Microsoft C versions 5.1, 6.0, 6.0a, 6.0ax, and C/C++ version 7.0,
scanf() may return different results when using the %i switch than when
using the %d switch. With the %i switch, reading in a number that begins
with a 0 (zero) will cause the number to be treated as an octal number.
The %d switch treats all numbers as decimal numbers.
More Information:
The %i switch has the capability of reading in decimal, octal, and
hexadecimal numbers. Hexadecimal numbers are specified with the 0x in
front of the number, while octal numbers are specified with the 0 in
front of them. If you want only decimal numbers to be read in, use the
%d switch.
This is expected behavior and occurs with the entire scanf() family.
