Lab 04 - Selection Statements & Iterations

Lab 04 - Selection Statements & Iterations
Instructions:
• The lab requires writing a complete cpp file within an hour. It requires completing 5 tasks.
• Accompanying this file is a template cpp file that you must modify. You cannot include additional
libraries to or remove any libraries from the file. All other modifications are allowed.
• Your submission must be submitted to the Labs directory of your github repository and/or as an
attachment on Google classroom under the Lab04 assessment. The file must remain a cpp file.
• Cheating of any kind is prohibited and will not be tolerated.
• Violating and/or failing to follow any of the rules will result in an automatic zero (0) for the lab.
TO ACKNOWLEDGE THAT YOU HAVE READ AND UNDERSTOOD THE INSTRUCTIONS ABOVE, AT
THE BEGINNING OF YOUR SUBMISSION, ADD A COMMENT THAT CONSISTS OF YOUR NAME AND
THE DATE
Your objective is to write a complete program that reads in a month and day for the year 2003, and then, displays the date
in the format
WeekDay , Month Day , 2003
where WeekDay and Month are represented as capitalized words. For instance, if the provided values for month and day are 2
and 19 respectively, the program will display
Wednesday, February 19, 2003
To accomplish the objective, complete the following tasks:
□ define a string function named MonthName() that takes an int parameter. If the value of the parameter is between 1 and
12 inclusively, the function returns the capitalized name of the month whose position in the calendar corresponds to the
value of the parameter. Otherwise, it returns an empty string.
□ define a bool function named ValidDate() that takes two int parameters. It returns true if the value of the first parameter
is a valid numerical representation for a month [1 - 12] and the value of the second parameter is a valid day in the month
represented by the first parameter. Otherwise, it returns false.
□ define a void function named RetrieveDate() that takes two int reference parameters. It continually prompts the user to
enter a month (numerical representation) and day separately, and then, it stores the inputs in the parameters until the
month and day are both valid [they represent an actually date in the year 2003].
□ define a string function named WeekDayName() that takes two int parameters. Given that the first parameter and second
parameter represents the month and day of a date in the year 2003 respectively, it returns the week day that correspond
to the date as a capitalized word. To determine the week day of any date in a year, use the formula
WeekDay = (FirstDay + DaysBeforeDate ) % 7
where WeekDay is represented numerically with the following correspondence
Week Day ''Sunday'' ''Monday'' ''Tuesday'' ''Wednesday'' ''Thursday'' ''Friday'' ''Saturday''
Value 0 1 2 3 4 5 6
and FirstDay is the numerically representation of January 1st of the year and DaysBeforeDate is the number of day
before the specified date. For instance, in 2003, January 1st falls on Wednesday (1) and there are 49 days before February
19th; hence, the formula determines that the week day for the 19th of Februrary is
WeekDay = (1 + 49) % 7
= 50 % 7
= 1
= ''Wednesday''
□ define a void function named DisplayDate() that takes no parameters. It retrieves the month and day of a date in the
year 2003 from the user and displays the date in the format mentioned above.
