问题:

I have problem with coding 1 app for toomorow lectures.

So, That program ask user for numbers, on typed "100" it's stops, and it shows: -average -min -max

I know what kind of loop, i need to use (do-while right?). But how i'm suppoused to count average,min,max without using arrays ?

回答1:

this is shorthand pseudo code because you have to code this yourself:

min = max = total = user_input count = 0 do {     count++     input = get_input     total += input     min or max maybe = input } while (input !=100) average = total / count print stuff

good luck

Step 1 : user three temp variable  Step 2 : initialize three temp variable(min,max,avg all by 0) Step 1 : inside the loop if temp > max ==>> max = temp Step 1 : inside the loop if temp < min ==>> min = temp Step 1 : avg = ( avg + temp )/i  int[] values = { .. values .. }  int min=0,max=0,avg = 0; for(int i=1;i<=values.length;i++) { if(min > values[i]) min = values[i]  if(max < values[i]) max = values[i]  avg = ( avg + values[i] ) / i }

I can tell you how to calculate average min and max without arrays. I cannot, however tell you how to calculate average min and max WITH arrays.

Minimum is easy:

int current_min ArrayList<int> find_min = new ArrayList<int>(); for (int c : find_min)     if (c < current_min)         current_min = c;

Maximum is a little bit harder. You need to use "functions"

boolean check_if_integer_is_bigger_than_another_integer(int another_integer_to_check_against, int the_original_integer_goes_here_into_this_argument_here) {     if (another_integer_to_check_against > the_original_integer_goes_here_into_this_argument_here)     return (another_integer_to_check_against > the_original_integer_goes_here_into_this_argument_here) //Important     return (another_integer_to_check_against > the_original_integer_goes_here_into_this_argument_here) }     int current_max     ArrayList<int> find_max = new ArrayList<int>();     for (int c : find_max)         if (check_if_integer_is_bigger_than_another_integer(c, current_max))             current_max = c;

I dont even want to go into averaging. You have to add numbers and I'm not exactly qualified for that.
