Write a C++ program to create a class Date with data members day,
month, and year. Use default. and parameterized constructor to initialize date
and display date in dd-Mon-yyyy format. (Example: Input: 04-01-2021 Output:
04-Jan-2021)
#include<conio.h>
#include<iostream.h>
class date
{
int dd,mm,yyyy;
public:
date(){}//default
constructor
date(int d,int m,int
y) // creating parameterized constructor
{
dd=d;
mm=m;
yyyy=y;
}
void disp()
{
if(mm>12)
cout<<"Invalid
Month."; //mm is month if it is greater than 12 then it is invalid.
else
cout<<"Input :
"<<dd<<"/"<<mm<<"/"<<yyyy<<endl;
if(mm==1)
{
cout<<"Output :
"<<dd<<"/"<<"jan"<<"/"<<yyyy;
}
else if(mm==2)
{
cout<<"Output :
"<<dd<<"/"<<"Feb"<<"/"<<yyyy;
}
else if(mm==3)
{
cout<<"Output :
"<<dd<<"/"<<"mar"<<"/"<<yyyy;
}
else if(mm==4)
{
cout<<"Output :
"<<dd<<"/"<<"apr"<<"/"<<yyyy;
}
else if(mm==5)
{
cout<<"Output :
"<<dd<<"/"<<"may"<<"/"<<yyyy;
}
else if(mm==6)
{
cout<<"Output :
"<<dd<<"/"<<"jun"<<"/"<<yyyy;
}
else if(mm==7)
{
cout<<"Output :
"<<dd<<"/"<<"july"<<"/"<<yyyy;
}
else if(mm==8)
{
cout<<"Output :
"<<dd<<"/"<<"Aug"<<"/"<<yyyy;
}
else if(mm==9)
{
cout<<"Output :
"<<dd<<"/"<<"sep"<<"/"<<yyyy;
}
else if(mm==10)
{
cout<<"Output :
"<<dd<<"/"<<"oct"<<"/"<<yyyy;
}
else if(mm==11)
{
cout<<"Output :
"<<dd<<"/"<<"Nov"<<"/"<<yyyy;
}
else if(mm==12)
{
cout<<"Output :
"<<dd<<"/"<<"Dec"<<"/"<<yyyy;
}
}
};
int main()
{
int d,m,y;
clrscr();
cout<<"Enter
a date : ";
