Correct Option: C

Which of these are not a kind of complex elements

  1. empty elements

  2. elements that contain only other elements

  3. elements that contain only text

  4. elements that contain only numbers


Correct Option: D

AI Explanation

To answer this question, you need to understand the concept of complex elements.

Complex elements are elements in HTML that can contain other elements and/or text. They are made up of a start tag, an end tag, and the content in between. Empty elements, on the other hand, do not have any content between the start and end tags.

Let's go through each option to understand whether it is a kind of complex element or not:

Option A) Empty elements - This option is not a kind of complex element because empty elements do not have any content between the start and end tags. Examples of empty elements in HTML include <br>, <img>, and ``.

Option B) Elements that contain only other elements - This option is a kind of complex element because it contains other elements within it. For example, <div> is a complex element that can contain other elements such as <p> or <span>.

Option C) Elements that contain only text - This option is a kind of complex element because it contains text between the start and end tags. For example, <p> is a complex element that can contain text.

Option D) Elements that contain only numbers - This option is not a kind of complex element because elements in HTML cannot contain only numbers. Elements can only contain text, other elements, or a combination of both.

The correct answer is D. Elements that contain only numbers are not a kind of complex element in HTML.

A default value is automatically assigned to the attributes when no other value is specified.

  1. FALSE

  2. TRUE

  3. NOT ALWAYS

  4. NONE OF THESE


Correct Option: B

  1. 10

  2. 11

  3. 1

  4. 0


Correct Option: B

What does the following code do: int c=0; cout<

  1. Undefined

  2. 01

  3. 00

  4. 10


Correct Option: A

What does the following do: void afunction(int *x) { x=new int; *x=12; } int main() { int v=10; afunction(&v); cout<

  1. Outputs 12

  2. Outputs 10

  3. Outputs the address of v

  4. Undefined


Correct Option: B

  3. 16.5

  4. Undefined


Correct Option: A

Can we have a virtual constructor for a class?

  1. True

  2. False

  1. There is none; they both work as expected

  2. They both do nothing.

  3. The first will not invoke all myObj destructors

  4. It would'nt delete all the memory allocated to the objects

  3. readline(x, 100, '\n');

  4. read(x);


Correct Option: A

What does the argument count variable store which is paased to main()?

  1. the number of arguments

  2. the number of arguments plus one

  3. the number of arguments minus one

  4. The total size of the argument array

  3. math.h

  4. None


Correct Option: D
