Question

Write a C++ program that determines the user's age after the user enters both the current date and hisher birthdate as 3 integers: yyyy mm dd Define a class which is named DateType and will be used to declare 2 objects: "birthday" and "today". The class will have a function "output" which will display the date in conventional form (like it is above next to Date Assigned: Month dd, yyyy EXAMPLE: If the user entered the #’s: 2018 2 6 then output would display Feb 6, 2018 After the user enters the birthdate, display the dates in conventional form and the user's age. EXAMPLE: If the user entered a birthdate: 1999 7 4 The program would display: Today is Feb 6, 2018 Your birthday was on Jul 4, 1999 You are 18 years old

Program Must Use a Class

Answer 1

This is the Output Screenshot of desired Program.

Below is the code:

C++ Code:

#include<iostream>
using namespace std;
class DateType
{
   public:
           int dd,mm,yyyy;
   public:
       void input()
       {
               cout<<"Enter Year:";
               cin>>yyyy;
               cout<<"Enter Month:";
               cin>>mm;
               cout<<"Enter Day:";
               cin>>dd;
       }
       void output()
       {
       if(mm==1)
       cout<<"Jan"<<" "<<dd<<", "<<yyyy;
       if(mm==2)
       cout<<"Feb"<<" "<<dd<<", "<<yyyy;
       if(mm==3)
       cout<<"Mar"<<" "<<dd<<", "<<yyyy;
       if(mm==4)
       cout<<"Apr"<<" "<<dd<<", "<<yyyy;
       if(mm==5)
       cout<<"May"<<" "<<dd<<", "<<yyyy;
       if(mm==6)
       cout<<"June"<<" "<<dd<<", "<<yyyy;
       if(mm==7)
       cout<<"July"<<" "<<dd<<", "<<yyyy;
       if(mm==8)
       cout<<"Aug"<<" "<<dd<<", "<<yyyy;
       if(mm==9)
       cout<<"Sep"<<" "<<dd<<", "<<yyyy;
       if(mm==10)
       cout<<"Oct"<<" "<<dd<<", "<<yyyy;
       if(mm==11)
       cout<<"Nov"<<" "<<dd<<", "<<yyyy;
       if(mm==12)
       cout<<"Dec"<<" "<<dd<<", "<<yyyy;
       }
  
};

int main ()
{
DateType birthday,today ;
cout<<"Enter Today's Date"<<endl;
today.input();
today.output();
cout<<endl;
cout<<"------------------------------------------------------------"<<endl;
cout<<"Enter Birth Date"<<endl;
birthday.input();
cout<<"Today is ";today.output();cout<<" Your birthday was on ";birthday.output();cout<<" You are ";
if(today.mm<=birthday.mm)
{
    if(today.dd<birthday.dd)
    cout<<today.yyyy-birthday.yyyy-1;
    else
    cout<<today.yyyy-birthday.yyyy;
}
else
cout<<today.yyyy-birthday.yyyy;
cout<<" years old";
cout<<endl;
cout<<"-----------------------------------------------------------"<<endl;

}
