year % 2 is 0 (i.e. false) if the year is even, and 1 (i.e. true, as is any non-zero value in C) if the year is odd. % is the "modulus" or "remainder" operator.

Good morning all!
I want to know if Im interpreting this if statement below right.
if(((1) || (0)) && (1)){
do stuff;
}
This is saying: if true piped into false, then true, then do stuff. Right?
What does the && stand for?
thanks in advance!

xcalev
XCALEV(1) General Commands Manual XCALEV(1)NAME
xcalev - load xcal calendar files with regular dates
SYNTAX
xcalev [ -r ][ -x ][ -f file ][ -d dir ][ year ]
DESCRIPTION
Xcalev is used to preload the calendar files for the xcal program with regular events in your life. It reads lines from a file (usually
called regular stored in your Calendar directory. Each line in the file contains three fields separated by spaces or tabs, these are: a
month name, a day in the month and some text. For example:
December 25 Christmas
Dec 31 New Year's Eve
The order of the month and the day are optional, the program deduces the day by looking whether the string contains an initial numeric
character or not. The year defaults to the current year unless the program is given a year number as an argument. This year cannot be
abbreviated to two digits because xcal
deals with years from year zero. There's a rough validity check on this.
The string from the data line is inserted in the appropriate file and will appear in your xcal date strip. Nothing will happen if the
string already exists in the file for that day. This means that it's safe to run xcalev at any time, only the strings that have altered in
the regular file will be updated.
To help with entering the same event for a number of days in one month, you can give a day range with a hyphen
Jan 16-21 Usenix SF
If you supply the -r option, xcalev will delete all the matching strings that it finds in the appropriate daily file. So, if you want to
make radical changes to the regular file, you should run xcalev with the -r option to remove all the current entries from one year, edit
the regular file and run xcalev to reload things.
OPTIONS
The -r option makes xcalev delete rather than append entries.
The -x option makes xcalev operate with Calendar files that are compatible with the xcalendar program.
The -f switch is followed by a filename gives an alternative name for the regular file. If the filename does not start with a slash or a
dot, then the name of your Calendar directory will be prepended to it.
The -d switch is followed by a directory name and specifies an alterative location for your Calendar directory. Your home directory is
prepended if the name doesn't start with a slash or a dot.
FILES
$HOME/Calendar/*
xc<dd><Mon><Year> A data file is day, Month in three letter format and the year.
xy<Year> A year directory.
xw<Day> A data file for the weekly code, one per day.
