❔ User inputs & arrays.

I am having the user input a max amount of values to store and using that input as my array length. I am then having the user input that amount of values individually. EX: User inputs 5, then inputs 1, 2, 3, 4, 5 I am trying to limit the amount of inputs to the max value inputted by the user. Everything I have tried so far allows the user to input more than the max amount they specified and I get Out of Range error. Anyone have a link to some documentation or some advice? I would prefer not to be outright told the answer.

Well, check what the user entered, and see if it's more than the array length?

if (userInput >= theArray.Length)
{
    Console.WriteLine($"⚠ No can do, maximum is {theArray.Length}");
}

if (userInput >= theArray.Length)
{
    Console.WriteLine($"⚠ No can do, maximum is {theArray.Length}");
}

define "limit the amount of inputs" like, prevent the user from typing in more than a certain amount of characters?

If the user inputs 5 as how many values they want to store, I want to make it so they can only enter 5 inputs

Use a list and keep checking the count

appiOP•2y ago

yeah, but the user will be pressing enter after every value

Angius•2y ago

If count reaches or exceeds maximum, don't allow input

JakenVeina•2y ago

oh, okay you made it seem like they would be entering all the array values at once, comma-separated

appiOP•2y ago

oops, sorry about that

var elements = new List<string>();
while (elements.Count < maximum)
{
    Console.WriteLine("Add new element");
    elements.Add(Console.ReadLine());
}

var elements = new List<string>();
while (elements.Count < maximum)
{
    Console.WriteLine("Add new element");
    elements.Add(Console.ReadLine());
}

if control is swapping back and forth between the program and the user, after every input, then you have full control over just... not allowing control to go back to the user

okay, that makes sense. thank you. I will try that would a for loop with a nested do while loop work?

JakenVeina•2y ago

probably sounds like overkill

appiOP•2y ago

i figured it out thank you gents
