Back To C++ Classes

a class in c++ is a group of data members and member functions that operate on data members
memory is allocated to a class when an object of the class is created
public members of a class can be accessed using dot operator(.) with the object of the class

//program to demonstrate example of class employee that contains two public member functions getdata() and showdata() and four data members (ecode,name,salary and designation) #include<iostream.h> #include<conio.h> class employee { int ecode; char name[20]; float salary; char designation[20]; public: void getdata() { cout<<"\nenter employee code"; cin>>ecode; cout<<"\nentername of employee"; cin>>name; cout<<"\nenter salary of employee"; cin>>salary; cout<<"\nenter designation of employee"; cin>>designation; } void showdata() { cout<<"\nemployee code is "<<ecode; cout<<"\nname of employee is "<<name; cout<<"\nsalary of employee is "<<salary; cout<<"\ndesignation of employee is "<<designation; } }; void main() { employee ob; //object of class employee is created here clrscr(); ob.getdata(); ob.showdata(); getch(); }
