need help with array program

[bigpotato]

What is it you are trying to achieve?
write a program that asks the user for the numbers of values they want(between 5-20), and then print the values out, including the average of the values and the largest and smallest values. the result would look like this

how many numbers would you like
5
Enter value #1 of 5
10
Enter value #2 of 5
20
Enter value #3 of 5
30
Enter value #4 of 5
40
Enter value #5 of 5
50

the mean is 30

the smallest value is 10 and the largest value is 50


What is the problem you are having?
I dont know how to declare a array that can change depends on the user and i dont know how to print them out.


Describe what you have tried to solve this problem
I made a variable called ValueNo and did array 1 .. ValueNo of int and that doesnt seem to work and now im stuck


Please specify what version of Turing you are using

Does the size of the array have to change?

[bigpotato]

it depends on the user but it doesnt change after the user has selected the size

Not a very nice way to do it, but you could do this:

Turing:

var numElements : int put "How many elements would you like?" get numElements var arr : array 1 .. numElements of int put "Your array has ", upper(arr), " elements."

numElements is just a number. This is totally valid.

You know there's never more than 20 elements, so you can just use an array of size 20 every time. You don't have to use every index. If there's only 5 elements, then you only use the first 5 indices of the array.

thank you, one more question, how can i make the program say "invalid input" if the number they enter is less than 5 and greater than 20, and make it keep saying it until they enter a valid input

Convert that sentence directly to code

Do something multiple times. You'll want a loop for that.
