+Question: Difference between encapsulation and abstraction ?
+
+
+Answer:
+
+Encapsulation:
+Encapsulation is about bundling data (attributes) and methods (functions) together, and restricting access to certain parts of the object. This helps in hiding the internal details and providing a clean interface for interacting with the object.
+
+
+#include <iostream>
+using namespace std;
+
+class EncapsulationExample {
+private:
+	// we declare a as private to hide it from outside
+	int a; 
+
+public:
+	// set() function to set the value of a
+	void set(int x) 
+	{
+		a = x;
+	}
+
+	// get() function to return the value of a
+	int get() 
+	{
+		return a;
+	}
+};
+
+// main function
+int main() 
+{
+	EncapsulationExample e1;
+
+	e1.set(10);
+
+	cout<<e1.get();
+	return 0;
+}
+
+
+The concept of abstraction only shows necessary information to the users. It reduces the complexity of the program by hiding the implementation complexities of programs.

+class Sum {
+private:
+    // private variables
+    int a, b, c; 
+public:
+    void sum(int x, int y)
+    {
+        a = x;
+        b = y;
+        c = a + b;
+        cout<<"Sum of the two number is : "<<c<<endl;
+    }
+};
+int main()
+{
+    Sum s;
+    s.sum(5, 4);
+    return 0;
+}
