The Answer is: C. <script>

  1. response.write("Hello World")

  2. document.write("Hello World")

  3. ("Hello World")

  4. echo("Hello World")


Correct Option: B
  1. call function myFunction

  2. myFunction()

  3. call myFunction()


Correct Option: B
Explanation:

To call a function named "myFunction", the user needs to use the following syntax:

myFunction();

Option A is incorrect because it is not the correct syntax for calling a function.

Option B is the correct answer because it calls the function "myFunction" using the proper syntax.

Option C is incorrect because it includes the word "call", which is not necessary when calling a function in most programming languages.

Therefore, the answer is: B. myFunction()

  1. if i==5 then

  2. if i=5 then

  3. if (i==5)

  4. if i=5


Correct Option: C
Explanation:

To write a conditional statement for executing some statements only if "i" is equal to 5, you need to use the correct syntax.

The correct syntax for a conditional statement in most programming languages is:

if (condition) {
    // statements to be executed if the condition is true
}

Now let's analyze each option and determine if it is the correct way to write the conditional statement:

A. if i==5 then - This option is incorrect because the syntax is incorrect. The correct syntax for the condition should be enclosed in parentheses, like if (i == 5).

B. if i=5 then - This option is incorrect because the syntax is incorrect. To check for equality, you need to use a double equals sign (==) instead of a single equals sign.

C. if (i==5) - This option is correct. It uses the correct syntax for a conditional statement. The condition i == 5 checks if the variable i is equal to 5.

D. if i=5 - This option is incorrect because the syntax is incorrect. To check for equality, you need to use a double equals sign (==) instead of a single equals sign.

Therefore, the correct option is:

The Answer is: C. if (i==5)

  1. Two. The "for" loop and the "while" loop

  2. Four. The "for" loop, the "while" loop, the "do...while" loop, and the "loop...until" loop

  3. One. The "for" loop


Correct Option: A
  1. for (i = 0; i <= 5)

  2. for (i = 0; i <= 5; i++)

  3. for i = 1 to 5

  4. for (i <= 5; i++)


Correct Option: B
  1. var txt = new Array(1:"tim",2:"shaq",3:"kobe")

  2. var txt = new Array="tim","shaq","kobe"

  3. var txt = new Array("tim","shaq","kobe")


Correct Option: C
