cout<<" Enter ink colour of pen - ";
cin>>ink_colour;
}
void prn_data()
{
cout<<" Price of pen : "<<price<<endl;
cout<<" Enter ink colour of pen : "<<ink_colour;
}

Coded Myself time : 14:50
#include<iostream>
#include<string.h>
using namespace std;

class animal{
private:
char gender;
int babbies;
public:
char name[50];
int legs;
int hands;
void setData(char, int);
void getData();
};

void animal :: setData(char gen, int bab){
gender = gen;
babbies = bab;
}

void animal :: getData(){
cout<<name<<":\n";
cout<<"\t gender : "<<gender;
cout<<"\t babbies : "<<babbies;
cout<<"\t legs : "<<legs;
cout<<"\t hands : "<<hands;

}
int main(){
animal kangaroo, dog;
kangaroo.hands = 2, kangaroo.legs = 2;
strcpy(kangaroo.name, "Kangaroo");
dog.hands = 0, dog.legs = 4;
strcpy(dog.name, "Dog");
kangaroo.setData('M', 3);
dog.setData('F', 2);

kangaroo.getData();
cout<<"\n";
dog.getData();

return 0;
}


Output :

Kangaroo:
gender : M babbies : 3 legs : 2 hands : 2
Dog:
gender : F babbies : 2 legs : 4 hands : 0
