What is object program?

Answer 1

friend, I'll explain an object in the context of class in CPP programming.

after the definition of a class , you can define an object belonging to that class.

for example,

class student

{ int rollno;

char name[10];

void getdetails()

{cout<<"enter the roll number and name of the student";

cin>>rollno;

gets(name);

}

void showdata()

{cout<<"the name is"<<name<<"and the rollnumber is"

<<rollno;

}} sara;

here sara is an object belonging to class student.

object sara can use the function getdetails() to get values to the identifiers rollno and name.

" Class is a group of objects with similar characters ( eg: rollno , name) and behaviour ( ie., the member functions-getdetails and showdata)"

" An object is a an entity with certain characters and behaviour"

here object sara denotes a student sara. now, you can create another object rahul to the class student by typing the code- student rahul;
