Computer Programming

Question

Goal: To bring together everything you've learned about repetition , relational operators, and input validation and show your mastery of these concepts.

You are to write a program that will allow a user to enter as many numbers as they want (one number at a time and all numbers must be greater than zero). You must have a way for the user to stop entering values. Once the user stops, you will immediately display the following:

1. The lowest number was:
2. The highest number was:
3. The number of values entered was:
4. The average of the numbers was:

Deliverables:

1. An IPO or Flowchart for the problem. (12 points)
2. A test case sheet that shows 3 sets of input data, and the expected results of running the
3. program for each set of input data. (12 points)
4. The code (with appropriate comments) that solves the problem – paste it into the Word
5. doc. (64 points)
6. Screen shots of running the program 3 different times. Use each of the test cases that you
7. have created. (12 points)

PROVIDE THE IPO PLEASE

Answer 1

java example is :

public class NumberStats {

public static void main(String[] args) {

Scanner scanner = new Scanner(System.in);

int number;

int count = 0;

int sum = 0;

int min = Integer.MAX_VALUE;

int max = Integer.MIN_VALUE;

System.out.println("Enter positive numbers (enter 0 or negative to stop):");

while (true) {

System.out.print("Enter a number: ");

number = scanner.nextInt();

// Stop condition

if (number <= 0) {

break;

}

// Update statistics

count++;

sum += number;

if (number < min) {

min = number;

}

if (number > max) {

max = number;

}

}

// Check if any numbers were entered

if (count == 0) {

System.out.println("No numbers were entered.");

} else {

double average = (double) sum / count;

System.out.println("Lowest number: " + min);

System.out.println("Highest number: " + max);

System.out.println("Number of values entered: " + count);

System.out.println("Average of numbers: " + average);

}

scanner.close();

}

}
