Abstract Data Types

_________________ is a collection of elements used to store the same type of data.

• Array

• Function

• Case

• Loop

Storage for data defined in terms of set of operations to be performed on the data 

• Arrays
• Variables
• Abstract Data Types
• Algorithms

Act of adding values into a stack is called

• Pop

• Poll

• Push

• Insert

If the elements “A”, “B”, “C” and “D” are placed in a stack and are deleted one at a time, in what order will they be removed?

• ABCD

• DCBA

• DCAB

• ABDC

Consider the following operation performed on a stack of size 5.

Push(1);

Pop();

Push(2);

Push(3);

Pop();

Push(4);

Pop();

Pop();

Push(5);

After the completion of all operation, get the total number of element present in stack is

• 1

• 2

• 3

• 4

Only the top element can be accessed in stack

• TRUE

• FALSE

Which of them is an abstract data structure (ADT)?

• Stacks

• Functions

• Queues

• Both A and C

Which of the following uses the FIFO method

• Queue

• stack

• linked list

• none of the above

Which function is called in a POP() function

• IsEmpty()

• IsFull()

Consider Stack is implemented using the array.

#define MAX 10

struct STACK

{

int arr[MAX]

int top = ___________;

}

What will be the initial value with which top is initialized.

• 0

• -1

• 10

• 1
