Program Plan Intro

Date Exceptions

Program Plan:

• Include the required header files.
• Declare a class named “Date”. Inside the class
  • Inside the “private” access specifier.
    • Declare private variables “month”, “day”, “year”.
    • Declare an array named “month_Names[]” and a private member function named “set_month_Names()”.
  • Inside the “public” access specifier,
    • Declare the default and parameterized constructor.
    • Declare the functions to set date, month and year.
    • Declare the functions to print the date formats.
• Inside the default constructor “Date()”,
  • Call the function to set the month names.
• Inside the parameterized constructor “Date (int m, int d, int y)”,
  • Call the function to set the month
  • Call the function to set the day
  • Call the function to set the year
  • Call the function to set the month names
• Give the function definition set month names
• Inside the “set_month_Names()” function,
  • Assign month names to the array “month_Names []”
• Give the function definition set month
• Inside the “set_Month()” function
  • Use “if” statement to check whether the “month” value is greater than or equal to 1 and less than or equal to 12
    • If the condition is true, then set the month.
    • If the condition is false, then throw an exception to indicate invalid month.
• Give the function definition set day
• Inside the “set_Day()” function
  • Use “if” statement to check whether the “day” value is greater than or equal to 1 and less than or equal to 31
    • If the condition is true, then set the day.
    • If the condition is false, then throw an exception to indicate invalid day.
• Give the function definition set year
• Inside the “set_Year()” function
  • Set the year.
• Function definition to print the “date_Format1()”.
  • Print the statement
• Function definition to print the “date_Format2()”.
  • Print the statement
• Function definition to print the “date_Format3()”.
  • Print the statement
• Define the “main()” function.
  • Declare and initialize the variables
  • Create an object for the class and instantiate the constructor
  • Inside the try block
    • Call the functions to print the “date_Format1()”, “date_Format2()”, “date_Format3()”.
  • Construct the catch blocks to handle the invalid day and month exceptions.
  • Return the statement.
