1. Write a program that does the following: - reads an unspecified number of integers - determines how many positive and negative values have been read - computes the total and average of the input values (not counting zeros). Your program ends with the input 0. Display the average as a floating-point number. If the entire input is 0, the program displays "No numbers are entered except 0". Here is a sample run: Enter integers ending with 0: 1 2 1 3 0 The number of positives is 3 The number of negatives is 1 The total is 5 The average is 1.25

Question

Transcribed Image Text:**Programming Exercises:**
1. **Develop a Program:**
- **Purpose:** Create a software program that:
- Accepts an unspecified number of integer inputs.
- Counts the positive and negative integers provided by the user.
- Calculates and outputs the total and average of the integers entered (excluding zeros).
- The program should terminate when the input is `0`.
- Display the average as a floating-point number.
- If the user enters only `0`, display the message: “No numbers are entered except 0”.
**Example Execution:**
```
Enter integers ending with 0: 1 2 -1 3 0
The number of positives is 3
The number of negatives is 1
The total is 5
The average is 1.25
```
2. **Pentagonal Number Calculation:**
- **Definition:** A pentagonal number is given by the formula \(n(3n-1)/2\) where \(n = 1, 2, \ldots\).
- The initial pentagonal numbers are 1, 5, 12, 22, ...
- **Task:** Develop a method with the header:
```java
public static int getPentagonalNumber(int n)
```
- **Examples:**
- `getPentagonalNumber(1)` returns `1`
- `getPentagonalNumber(2)` returns `5`
- **Objective:** Write a test program that outputs the first 100 pentagonal numbers, displaying 10 numbers per line. Numbers should be separated by one space.
