Question

Print 3 numbers before asking a user to input an integer

Answer 1

you can use an array to do this

Step-by-step explanation:

(I've written this in java - I think it should work out):

Scanner input = new Scanner(System.in);

System.out.println("Enter an integer: ");

int userInt = input.nextInt();

int[] array = new int[userInt - 1];

for(int i = userInt-1; i < userInt; i--)

System.out.println(array[i]);

Answer 2

The code displays three random numbers, prompts the user for an integer, and validates the input. Enhancing clarity, it fosters a user-friendly interaction.

Certainly! Here's a simple code snippet that displays three numbers before prompting the user to input an integer:

```

# Generate three random numbers for display

random_numbers = [random.randint(1, 100) for _ in range(3)]

# Display the three numbers

print(f"Consider the following three numbers: {', '.join(map(str, random_numbers))}")

# Prompt the user to input an integer

user_input = input("Now, please input an integer: ")

# Validate if the user input is an integer

try:

user_integer = int(user_input)

print(f"You entered: {user_integer}")

except ValueError:

print("Invalid input. Please enter a valid integer.")

```

In this example, the `random_numbers` list is generated with three random integers between 1 and 100. The code then prints these numbers as part of the prompt before asking the user to input an integer. The user's input is then validated to ensure it is indeed an integer.
