-portfolio » cprogproject4
+A project for C/C++ programming, CSCS1320S14, by Alana Whittier during the Spring semester 2014.
---------------------------------------------------------------------------------
+This project was begun on March 7, 2014 and it took nearly 3 days to complete.
- <!DOCTYPE html>
+=====Objectives=====
-<html lang="en" dir="ltr" class="no-js">
+The purpose of this project is to write a program that utilizes a mental math trick to determine what day of the week that January 1st of any given year falls on in the 21st century. A two digit year (between 2001 and 2099) is input from the user and is computed using a series of selection statements to derive the day of the week that Jan 1st falls on per calendar year, minus one day for leap years.

+=====Background=====
+The purpose of this project is to use a mental math technique to programmatically compute the day on which January 1st falls per given calendar year in the 21st century. The "mental math" trick is used to simplify the process of computation without being dependent on a calculator. To see how this particular technique works for computing the week day that January 1st falls on, see the assignment link below.
+[[haas:spring2014:cprog:projects:dayofweek|Project: MENTAL MATH (DAY OF WEEK)]]
+To implement the program to compile and execute successfully, it is required to know how to determine leap years from non-leap years. As we experience leap years as much as every four years, simple algorithms can be used to determine the leap year. However, every 100 years, a leap year is skipped to make up for the 11 minutes removed from the 365.25 day calendar year.
+=====Scope=====
-<!-- ********** HEADER ********** -->
+The scope of the project is to write a program that utilizes the described mental math technique (see assignment in Background section above) to compute the week day that January 1st happens to fall on for a given year in the 21st century (2000-2099). In doing so, the program should prompt the user for the last two digits of the year, perform the calculation of the day of the week that January 1st falls on for the year given by user input, and display the value. Applying pointers to enable the use of scanf() for obtaining input from the user, using if() statements, are used in the implementation of this program.
-<div id="dokuwiki__header"><div class="pad group">
+=====Attributes=====
+ Upon successful completion of this project, the following attributes are achieved.
+  * More familiarity with pointers and scanf: This project requires user input.
-    <div class="headings group">
+  * Become more exposed to selection statements: if statements are used to compute the day of the week January 1st falls on per given calendar year.
-        <ul class="a11y skip">
+  * Get more comfortable with Bitwise && operators: used to differentiate between leap years and non-leap years to obtain the correct output.

+=====Reflection=====
+Interestingly enough, the year 2000 would not be a leap year if only using the first 2 criteria.
+The criteria:
+  - If year is evenly divisible by 4, it is a leap year.
+  - If year is evenly divided by 100, it is not a leap year, except when
+  - the year is also evenly divisible by 400.
-<h2 class="sectionedit4" id="background">Background</h2>
+The year 2000 is a significant calendar year because it was the first instance when the third criteria was invoked since switching from the Julian calendar to the Gregorian one. The reason for leap years? This was necessary to keep our calendar in alignment with Earth's revolutions around the sun. If we did not add a day to our calendar ~every 4 years, we would lose nearly 6 hours every year, so after 100 years our calendar would be off by nearly 24 days as measured by earth's revolutions. Why is a leap year skipped every 100 years, except in special instances (like year 2000)? This is to account for the 11 minutes shaved off from the 365.25 calendar year.
-<div class="level2">
-<p>
+While I wrote my code more simplistically saying if i divided by 4 equals zero, then it is a leap year and if i divided by 4 does not equal zero, not a leap year, the code worked. I could have added that i/100==0 || i/400==0 is a leap year to make my code more realistic to how the calendar interprets leap years from non-leap years, particularly in special instances such as 2000.
