+Design a class named Box whose dimensions are integers and private to the class. The dimensions are labelled: length , breadth , and height .
+
+The default constructor of the class should initialize , , and  to .
+
+The parameterized constructor Box(int length, int breadth, int height) should initialize Box's  and  to length, breadth and height.
+
+The copy constructor BoxBox ) should set  and  to 's  and , respectively.
+
+Apart from the above, the class should have  functions:
+<li>int getLength() - Return box's length</li>
+<li>int getBreadth() - Return box's breadth </li>
+<li>int getHeight() - Return box's height </li>
+<li>long long CalculateVolume() - Return the volume of the box </li>
+
+Overload the operator < for the class Box. Box **A <** Box **B** if:
+<ol>
+<li> A.l < B.l</li>
+<li> A.b < B.b and A.l == B.l</li>
+<li>A.h < B.h and A.b==B.h and A.l==B.l</li>
+</ol>
+
+Overload operator **<<** for the class Box().
+
+If **B** is an object of class Box:
+
+**cout << B** should print **B.l,B.h** on a single line separated by spaces. 
+
+For example,
+
+    Box b1; // Should set b1.l = b1.b = b1.h = 0;
+    Box b2(2, 3, 4); // Should set b1.l = 2, b1.b = 3, b1.h = 4;
+    b2.getLength();	// Should return 2
+    b2.getBreadth(); // Should return 3
+    b2.getheight();	// Should return 4
+    b2.CalculateVolume(); // Should return 24
+    bool x = (b1 < b2);	// Should return true based on the conditions given
+    cout<<b2; // Should print 2 3 4 in order.
+
+**Constraints**
+
+**0<=l,b,h<=10<sup>5</sup>**
+
+Two boxes being compared using the < operator will not have all three dimensions equal.
