What is the difference between print() and println() in Kotlin?
print() outputs text without moving to a new line, so the next output continues on the same line. println() outputs text and then moves to a new line, so the next output starts on the next line.

What will be the output of this Kotlin code?
print("Hello")
print("World")
The output will be HelloWorld on the same line because print() does not add a new line after printing.

What will be the output of this Kotlin code?
println("Hello")
println("World")
The output will be:
Hello
World
Each word is printed on its own line because println() adds a new line after printing.

Can you use print() and println() together? What happens?
Yes, you can mix them. print() will print text without moving to a new line, and println() will print text and then move to a new line. This lets you control exactly how your output looks.

How do you print a variable value in Kotlin using println()?
You can print a variable by placing it inside println() using string templates like this:
val name = "Alice"
println("Hello, $name!")
This will output: Hello, Alice!

What does println() do after printing text?
AMoves to a new line
BPrints text without moving to a new line
CDeletes the printed text
DPrints text twice
What will this code print?
print("Hi")
println(" there")
AHi (on one line) and there (on same line)
BHi (on one line) and there (on next line)
CHi there (on one line)

      1. What is the main difference between print and println in Kotlin?
      easy
      A. print outputs only numbers; println outputs only text.
      B. print adds a newline after output; println outputs text without a newline.
      C. print outputs text without a newline; println adds a newline after output.
      D. print is used for debugging; println is used for user messages.

      Solution

      1. Step 1: Understand print behavior

        print outputs text exactly as given and stays on the same line.

      2. Step 2: Understand println behavior

        println outputs text and then moves the cursor to the next line.

      3. Final Answer:

        print outputs text without a newline; println adds a newline after output. -> Option C

      4. Quick Check:

        print no newline, println newline = A [OK]
      Hint: Remember: println adds a line break, print does not [OK]
      Common Mistakes:
      • Confusing which function adds a newline
      • Thinking print adds a newline
      • Assuming println outputs only numbers
      2. Which of the following is the correct syntax to print "Hello" and then move to a new line in Kotlin?
      easy
      A. println("Hello")
      B. print("Hello")
      C. println Hello
      D. println["Hello"]

      Solution

      1. Step 1: Check syntax correctness

        Only println("Hello") uses correct function call syntax with parentheses and quotes.

      2. Step 2: Verify output behavior

        println("Hello") prints "Hello" and moves to a new line automatically.

      3. Final Answer:

        println("Hello") -> Option A

      4. Quick Check:

        Correct syntax with println = A [OK]
      Hint: Use parentheses and quotes exactly for print/println [OK]
      Common Mistakes:
      • Missing parentheses around arguments
      • Using square brackets instead of parentheses
      • Omitting quotes around strings
      3. What will be the output of the following Kotlin code? 
      print("Hi")
println(" there")
print("Welcome")
      medium
      A. Hi there Welcome
      B. Hi there Welcome
      C. Hi there Welcome
      D. Hi there Welcome

      Solution

      1. Step 1: Trace first print statement

        print("Hi") outputs "Hi" without newline.

      2. Step 2: Trace println statement

        println(" there") outputs " there" and moves to next line.

      3. Step 3: Trace last print statement

        print("Welcome") outputs "Welcome" on the new line.

      4. Final Answer:

        Hi there Welcome -> Option D

      5. Quick Check:

        print no newline, println newline = D [OK]
      Hint: Remember print stays on line; println moves to next line [OK]
      Common Mistakes:
      • Assuming print adds newline
      • Ignoring space in " there"
      • Thinking all output is on one line
      4. Identify the error in this Kotlin code snippet: 
      print("Hello")
println "World"
      medium
      A. Missing parentheses in println call
      B. Missing quotes around Hello
      C. print cannot be used without println
      D. No error, code runs fine

      Solution

      1. Step 1: Check syntax of print statement

        print("Hello") is correct with parentheses and quotes.

      2. Step 2: Check syntax of println statement

        println "World" is missing parentheses around the argument, which is required in Kotlin.

      3. Final Answer:

        Missing parentheses in println call -> Option A

      4. Quick Check:

        Function calls need parentheses = B [OK]
      Hint: Always use parentheses for function calls in Kotlin [OK]
      Common Mistakes:
      • Omitting parentheses in function calls
      • Thinking print needs println to work
      • Confusing quotes usage
      5. You want to print the numbers 1, 2, and 3 on the same line separated by spaces, then print "Done" on the next line. Which Kotlin code achieves this?
      hard
      A. print("1 2 3") print("Done")
      B. print("1 2 3") println("Done")
      C. print("1 ") print("2 ") print("3\n") println("Done")
      D. println("1") println("2") println("3") print("Done")

      Solution

      1. Step 1: Print numbers on same line with spaces

        Using print("1 2 3") outputs "1 2 3" on the same line.

      2. Step 2: Print "Done" on next line

        println("Done") prints "Done" and moves to the next line.

      3. Final Answer:

        print("1 2 3") println("Done") -> Option B

      4. Quick Check:

        Use print for same line, println for new line = A [OK]
      Hint: Use print for same line, println to move to next line [OK]
      Common Mistakes:
      • Using println for each number causing new lines
      • Using print after println without newline
      • Adding \n inside print incorrectly
