Answer: object that persist set of values and operations as behavior
Explanation: Abstract data types(ADT)are those object value which are dependent upon the collection of the values and collection of the operations.The organization of the data object is not specified in ADT but the operations that are to be carried out are defined in it.
The implementation individuality displayed by the ADT and hiding of the representation or design makes it abstract.
Answer:
Class are the collection of variable and member function.
Class are the blueprint of an object.
Explanation:
Following are the points regarding class in c++
1.In C++ class is an user defined datatype..
2.Classes are the collection of variable and function in c++.
3.To access the property of class we can create object of that class
4.We can use following syntax to declared any class in c++
class classname
{
accessmodifier:
//statement and function
};
main()
{
classname objectname;
}
implementation of class in c++
#include<iostream>
class test // class declaration
{
public: // access modifier
void fun3() // Method definition
{
cout<<" hello :";
}
};
void main() // main function
{
test ob;// creating object
ob.fun3(); // calling function
}
In this program we declared a class "test " in class test. We giving public access modifier .The public access modifier define that variable and function are accessible outside the class and in main method we create the object ob which call the function fun3().
Output:hello :
