(10 points) [Edhesive] 3.6 Code Practice
Digiron [165]

Answer:

  • You need to create a variable outside (before) the input loop.
  • You need a variable inside your loop that temporarily holds the user input.
  • In your loop, you will compare if the variable outside the loop is greater than (or less than) the new user input.

I don't know what program language you are using, but I will use python since it's easy to read and you will get the idea if you're using a different programming language.

<u>Code (Python)</u>

largestnum = 0

for x in range(6): <em>#loops 6 times</em>

   newnum = int(input("Enter a number: ")) #ask user for input & converts to int.

   if newnum > largestnum: <em>#if new number is greater than largest num </em>

     largestnum = newnum     <em>#make it the largest number</em>

<em>    </em>print("Largest:", largestnum)

The reason why you need a variable outside of the loop is because after the loop is done all variables inside the loop are trashed and can no longer be accessed outside of the loop.
