Question

Can someone please help me. i keep getting an error in my code. I need it to be on three seperate files!

attached is my assignment and my code. c++

The class date Type implements the date in a program. Write the class functions as specified in the UML class diagram. The values for the month, day, and year should be validated (in the class functions) before storing the date into the data members. Set the invalid member data to the initialization value shown in the UML. i.e. if the passed day is 38, should be set to 1. Also, if the passed day is 31 and the month is 4, this is invalid and the day should be set to 1. Add a member function, isLeapYear, to check whether a year is a leap year. Demonstrate your class in a program. date Type -dMonth: int -d Day: int -dYear: int +setDate(int, int, int) : void +getDay () const: int +getMonth() const: int +getYear() const: int +printDate() const: void +dateType (int -1, int -1, int - 1900)

Answer 1

1.)

prototype for 'void DataType::isLeapYear()' does not match any in class 'DataType'

You are getting this error because the return type of isLeapYear() during is actually int as per the declaration in line 25 of your class file but, while writing function definition for isLeapYear() in line 79, you have given the return type as void. Change line 25 of your class file to:
void isLeapYear();

2.)

candidate is: int DataType::isLeapYear()

you get this error because the function definition of isLeapYear() must be

int DataType::isLeapYear()

{

}

not

void DataType::isLeapYear()

{

}

because, the function declaration in line 25 if class file looks like

int isLeapYear();

However, this error must be gone once you have solved error 1.)

So, this must not be a problem.

3.)

'cout' was not declared in this scope

you get this error because, in class file there is a 'cout' inside printDate() function but the header file iostream was not included. cout is defined in iostream, so it is necessary to include iostream in whichever file cout is being used.

add this line at the beginning of the class file:

#include<iostream>

or alternatively,

you can just remove the definition of printDate() because i see that you are defining the function in the other file with all the function definitons.

That must clear the 3 errors being shown. If you need more information, please reach out to me in comment section.
