❔ Is there any way I can populate arrays with user input?

For example I want a user to fill up an array named randomNumbers with well, random numbers, can I do that? and if so, how?

1. Create an array 2. Loop over the array 3. For each index of the array, set the value at the index to a random number You'll need to know a couple things for this, mainly how to create arrays, how to loop over them using a for loop, and how generate random numbers using the Random class.

Sounds like they want the random numbers to come from the user

I know how to use randoms and stuff but I want the numbers to come from the user

Do you know how to read user input?

Like a ReadLine thing but it populates an array instead of a variable yep

Do you know how to turn a string into an int?

Convert.toInt32/64 I believe

int.Parse is better, but yes So you need to create the array, loop over it, and set each element to a number inputted by the user

int[] array1 = new int[5];

for(int i = 0; i < array1.Length; i++)
{
    array1[i] = Convert.ToInt32(Console.ReadLine());
}

int[] array1 = new int[5];

for(int i = 0; i < array1.Length; i++)
{
    array1[i] = Convert.ToInt32(Console.ReadLine());
}
