Question

c++ design a class named myinteger which models integers. interesting properties of the value can be determined. include these members: a int data field named value that represents the integer's value. a constructor that creates a myinteger object with a specified int value. a constant getter that returns the value

Answer 1

Answer:

1. #include <iostream>
3. using namespace std;
5. class myinteger {
6.    
7.    private:
8.        int value;
9.        
10.    public:
11.        myinteger(int x){
12.            value = x;
13.        }
14.        
15.       int getValue(){
16.           return value;
17.       }
18.        
19. };
21. int main()
22. {
23.    myinteger obj(4);
24.    cout<< obj.getValue();
26.    return 0;
27. }

Explanation:

Firstly, we use class keyword to create a class named myinteger (Line 5). Define a private scope data field named value in integer type (Line 7 - 8).

Next, we proceed to define a constructor (Line 11 - 13) and a getter method for value (Line 15 -17) in public scope. The constructor will accept one input x and set it to data field, x. The getter method will return the data field x whenever it is called.

We test our class by creating an object from the class (Line 23) by passing a number of 4 as argument. And when we use the object to call the getValue method, 4 will be printed as output.
