In a While loop a code will be repeated until the condition becomes

• FALSE

• TRUE

• User choice

Print i as long as i is less than 6.

What will be the code?

• i = 1

  while i < 6:

  print(i)

  i += 1

• i = 1

  when i < 6;

  print(i)

  i += 1

• i = 1

  i < 6:

  print(i)

  i += 1

In programming, what is iteration?

• The repetition of steps within a program
• The order in which instructions are carried out
• A decision point in a program
• Testing a program to make sure it works

Which is the correct format of a do-while loop?

• do-while(condition);

  {

  //code

  }

• do{

  //code

  }while(condition);

• do-while(condition)

  {

  //code

  }

• do{

  //code

  }while(condition)

What is the main difference between a WHILE and a DO-WHILE loop in Java?

• WHILE loop executes the statements inside of it at least once even if the condition is false.

• DO-WHILE loop executes the statements inside of it at least once even if the condition is false.

• WHILE loop is fast.

• DO-WHILE loop is fast.

What is the value of "age" in the below Java program with a DO-WHILE loop?

do

{

age++;

}while(age<20);

System.out.println(age);

• 20

• 21

• Compiler error

• None

• 1,2,3

• 1,2,3,4,

• 1,2,3,4

Give the output and show the dry run.
