● 1] Design an employee class for reading and displaying the
employee information.
Input:
#include <iostream>
using namespace std;
class employee
{ int age;
char name[20];
float sal; void
getInfo()
{
cout<<"Enter your name ,age and salary :=";
cin>>name>>age>>sal;
}
public:
void displayInfo()
{ getInfo(); cout<<"\n your name ,age and salary are"<<name<<"\
n"<<age<<"\n"<<sal;
}
};
int main()
{
employee e;
e.displayInfo();
return 0;
}

Fruit information.
Input:
#include <iostream>
using namespace std;
class Fruit

int num; char
name[20]; float
price; void
getInfo()
{
cout<<"Enter number of fruit,name of fruit,price of fruit:";

two of its methods which will be used for reading and displaying the
student information respectively where getData() will be a private
method.

3] Design the class Demo which will contain the following
methods: readNo(), factorial() for calculating the factorial of a
number, reverseNo() will reverse the given number,
isPalindrome() will check the given number is palindrome,
isArmstrong() which will calculate the given number is
AarmStrong or not.Where readNo() will be a private method.
