If any class contain abstract method then, it must be declare as abstract. Therefore, if a class are not implemented an interface method then, it should be declare as abstract.

viktelen [127]

Answer:

C. Appliance.

Explanation:

When a device or machine performs a single function or task, it is commonly referred to as an appliance. Examples of such is an iron, a calculator, a computer game, washing machines, refrigerators, e.t.c

<em>A Personal Digital Assistant (PDA)</em>, is a device, mostly mobile and handheld, that combines various computing features such as telephoning and networking. An example is a tablet. A PDA performs more than a single function.

<em>Minicomputer</em> is a computer usually small in physical size, that is midway in capabilities and support, between a microcomputer and a mainframe computer. An example is also a tablet and our smartphones. Minicomputers are also dedicated to various functions rather than a single function.

In summary, the option that best describes the situation in the question is an appliance.

<em>Hope this helps!</em>

Write a recursive function that calculates if two binary trees are similar?
ahrayia [7]

Answer:

bool identicaltrees(Node* root1,Node* root2)//function of type boolean true if idenctical false if not.

{

   if(root1==NULL&&root2==NULL)//both trees are null means identical.

   return true;

   if(roo1 && root2)

   {

       if(root1->data==root2->data)//condition for recursive call..

       {

           return (identicaltrees(root1->left,root2->right)&&identicaltrees(root1->right&&root2->right);

       }

   }

   else

   return false;

}

Explanation:

In this function it of type boolean returns true if both the trees are identical return false if not.First we are checking root node of both the trees if both are null then they are identical returning true.

If both root nodes are not null then checking their data.If data is same then recursively traversing on both trees and checking both trees.

else returning false.
