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 4.05 |

Does the size of the array have to change? |

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:
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 |

Quote: if the number they enter is less than 5 and greater than 20
Convert that sentence directly to code Quote: keep saying it until they enter a valid input
Do something multiple times. You'll want a loop for that. |
