Description

This assignment is the same as the last assignment except you are to additionally include the input validation code in this assignment.

This assignment will validate (check) the values of day, month, and year entered by the user to ensure that they are valid (correct) before computing day number. If any value is invalid (incorrect), the program will display an error message and end. The program will do the input validation (checking) before computing the day number.

The program will validate (check) the input values to ensure that:

Year value (entered by the user) is in the range of 2000 to 2099 inclusive.

Month value (entered by the user) is in the range of 1 to 12 inclusive.

Day value (entered by the user) is valid (correct) for the given month and the year.

Note:

Do input validation (checking) immediately after inputting the value (from the user) and before computing the day number.

Testing

Input Test Run 1

Enter Month: 4

Enter Day: 31

Enter Year: 2003

Output Test Run 1

Mismatching Month/Day Values Entered.

Month Value Entered: 4

Day Value Entered: 31

Sample Code

/*

First, input from the user (ask the user to enter) month, day and year one after the other.

Then, validate (check) the input (values entered by the user). If any of the values is invalid (incorrect), display an error message to the effect and end the program.

When all input values (values entered by the user) are validated (checked), only then compute and display the dayNum.

See the sample code below.

*/

//For doing this assignment, follow the code sequence as shown below.

int day, month, year, dayNum;

//Input day, month, and year values.

//Validate input values

//Determine if it's a Leap year

bool leapyear = false;

if ((year % 4) == 0)

{

leapyear = true;

}

//Validate YearValue

if ( year < 2000 || year > 2099 )

{

cout << Unacceptable Year Entered: << year << endl;

cout << Valid Range For Year 2000 to 2099 << endl;

return 0;

}

//Validate Month Value

if ( month < 1 || month > 12 )

{

cout << Invalid Month Entered: << month << endl;

return 0;

}

//Validate Day Value

if ( ( day < 1 ) || ( day > 31 ) )

{

cout << Invalid Day Entered: << day << endl;

return 0;

}

//Validate Other Day Values

if ( ( month == 4 || month == 6 || month == 9 || month == 11) && ( day > 30 ) )

{

cout << Mismatching Month/Day Values Entered. << endl;

cout << Month Value Entered: << month << endl;

cout << Day Value Entered: << day << endl;

return 0;

}

if ( (month == 2) && ( day > 29 ) && ( leapyear ) )

{

cout << Mismatching Month/Day Values Entered: << endl;

cout << Month Value Entered: << month << endl;

cout << Day Value Entered: << day << endl;

return 0;

}

if ( (month == 2) && ( day > 28 ) && ( ! leapyear ) )

{

cout << Mismatching Month/Day Values Entered: << endl;

cout << Month Value Entered: << month << endl;

cout << Day Value Entered: << day << endl;

return 0;

}

//Determine dayNum

//Display the date and dayNum
