Step 1: Design a flowchart or write pseudocode for a program that allows a user to enter 12 numbers, then displays all of the numbers (in the order they were entered) as well as the largest number and the smallest number.

Step 2: Implement and test your design using VisualLogic.

n = 0

1 read x

n = n + 1

print x

If n > 1, go down to 2

small = x
large = x

2 If x</= small, then small = x
If x>/= large, then large = x

If n < 12 , go back up to 1

Print small
Print large
end

To design a program that allows a user to enter 12 numbers, displays all of the numbers (in the order they were entered), as well as the largest and smallest numbers, you can follow these steps:

Step 1: Start by creating a flowchart or writing pseudocode to outline the logic of the program.

Here's an example of a flowchart to achieve this task:

Start
Declare variables smallest, largest, and an array of size 12 called numbers
Initialize the variables smallest and largest to an initial value

For i = 0 to 11:
Read numbers[i] from the user

Set smallest = numbers[0]
Set largest = numbers[0]

For i = 1 to 11:
If numbers[i] < smallest, then set smallest = numbers[i]
If numbers[i] > largest, then set largest = numbers[i]

Print "The numbers entered are:"
For i = 0 to 11:
Print numbers[i]

Print "The smallest number is: " + smallest
Print "The largest number is: " + largest

End

Step 2: Implement and test the design using VisualLogic or any other programming language.

Please note that this explanation assumes you are familiar with the basics of programming and have access to the necessary tools like VisualLogic or a programming language of your choice to implement the code.
