By using encapsulation, we can create classes in different modes such as read-only and write-only mode. Another benefit of encapsulation is that we reduce human error because we write code in a proper manner and suitable. Let’s consider a simple example of a washing machine; in this scenar...
In general, encapsulation is a process of wrapping similar code in one place. In C++, we can bundle data members and functions that operate together inside a single class. For example, classRectangle{public:intlength;intbreadth;intgetArea(){returnlength * breadth; } }; ...
When the above code is compiled and executed, it produces the following result −Length: 4.5 Width: 3.5 Area: 15.75 In the preceding example, the member variables length and width are declared public, so they can be accessed from the function Main() using an instance of the Rectangle ...
A practical example involves graphical user interface (GUI) components: buttons, sliders, and text fields encapsulate rendering algorithms and event-handling procedures, enabling programmers to utilize these elements without understanding their underlying code....

In PHP, the class members (both member variables as well as member functions) are public by default.ExampleIn the following program, the member variables title and price of the object are freely accessible outside the class because they are public by default, if not otherwise specified....
In the example code below, the setter methods appropriately screen the internal values of latitude and longitude. Rather than throw an exception, I specify performing modulo arithmetic on input values to keep the internal values within specified ranges. For example, attempting to set the latitude ...
Example #include <iostream>using namespace std;class Employee { private: // Private attribute int salary; public: // Setter void setSalary(int s) { salary = s; } // Getter int getSalary() { return salary; }};int main() { Employee myObj; myObj.setSalary(50000); cout << myObj....
