   4. A statement that defines variables
   Show answer

   Answer: B. A statement that executes based on a condition

   A conditional statement allows execution of certain parts of the code based on whether a condition is true or false, making it a key concept in programming.

2. What will the following code print? if (true) { console.log('Yes'); } else { console.log('No'); }

   1. Yes
   2. No
   3. Nothing
   4. Error
   Show answer

   Answer: A. Yes

   Since the condition is 'true', the first block will execute, printing 'Yes' to the console.

3. What will be the output of the following code block? var a = 10; if (a == 10) { console.log('Ten'); } else { console.log('Not Ten'); }

   1. Ten
   2. Not Ten
   3. Error
   4. Nothing
   Show answer

   Answer: A. Ten

   The value of a is equal to 10, so the condition is true, and 'Ten' will be printed.

4. What will happen if none of the if or else-if conditions are satisfied?

   1. The program will stop
   2. An error will occur
   3. The else block will execute if present
   4. Nothing will happen
   Show answer

   Answer: C. The else block will execute if present

   If all if and else-if conditions are false, the else block, if defined, will execute, allowing for a default action.

5. How can an 'if' statement be terminated in programming?

   1. With a semicolon ;
   2. With a period .
   3. With a comma ,
   4. With a curly brace }

   An 'if' statement block in most programming languages is terminated by a curly brace to signify the end of the conditional block.
