Question

Problem:

You will write a program to compute some statistics based on monthly average temperatures for a given month in each of the years 1901 to 2016. The data for the average August temperatures in the US has been downloaded from the Climate Change Knowledge Portal, and placed in a file named “tempAugData.txt”, available on the class website. The file contains a sequence of 116 values. The temperatures are in order, so that the first one is for 1901, the second is for 1902, and so on through 2016.

The statistics you should compute in your program are:

• The average of the monthly average temperatures for the entire time period.

• The number of years that the monthly average reached at least X degrees where X is a value input from the user. These years should also be displayed to the screen.

• The maximum monthly average temperature for the time period and in what year it occurred.

• The minimum monthly average temperature for the time period and in what year it occurred.

Input: Your program should ask the user for the name of the file, and then open that file for input. It should then ask the user for a boundary temperature (the X in the second bullet above) that is used to calculate some of the statistics. Processing: Compute the statistics requested above.

Output: Display the statistics, labeled, and with the temperatures formatted to 1 decimal place. Also output the count of the years above X before outputting the list of the years.

Sample output:

Please enter the name of the temperature data file: tempAugData.txt Please enter the boundary temperature: 68.0

Climate Data statistics: Average temperature: 66.2

Years that averaged at least 68.0 degrees: 7 1936 1995 2003 2007 2010 2011 2016

Maximum average temperature: 68.9 occurred in 2007

Minimum average temperature: 63.9 occurred in 1927

Additional Requirements:

• Your program must compile and run, otherwise you will receive a 0.

• Your program should test for file open errors.

• I recommend temporarily echoing the input from the file to the screen (using cout) to be sure you are reading the input correctly into your array.

• You should have many separate loops in your program. Do not try to compute everything in one single loop.

• For partial credit, implement some subset of the features completely. This will probably lead to a better score than implementing every feature poorly.

Thanks for the question, Here is the complete program in C++

Answer 2

A corporation named XYZ needs a program to calculate how much to pay their part-time and full-time

employees.

For full-time employees, the employees get paid time and a half for any hours over 40 that they work in a single

week. For example, if an employee works 45 hours, they get 5 hours of overtime, at 1.5 times their base pay. The

base should be at least RS. 120 an hour. This XYZ Corporation requires that an employee not work more than 60

hours in a week.

For part-time employees, they get paid time and a half for any hours over 30 that they work in a single week.

For example, if an employee works 33 hours, they get 3 hours of overtime, at 1.5 times their base pay. Their base

pay should not be less than RS. 110 an hour. This XYZ Corporation requires that an employee not work more

than 35 hours in a week.

To sum up:

 An employee gets paid (hours worked) × (base pay) for each hour up to 30 or 40 hours depending upon

employee type.

 For every hour over 30 or 40 depending upon employee type, they get overtime = Overtime hours × (base

pay) × 1.5.

 The base pay must not be less than the minimum wage (RS. 110 or RS. 120 an hour depending upon

employee type).

 The working hours must not exceed 35 or 60 depending upon employee type.

Write a program that ask user to enter Employee Name, Employee type (full-time/pat-time), working hours and

base pay. You need to write the following methods:

1. Write a method that validates the input that if it is in given range or not.

public static boolean isValidInput(Char empType, int workingHours, double

basePay)

2. A method that calculate pay based on given parameters.

public static double calculatePay(Char empType, int workingHours, double

basePay)

3. A method to calculate overtime pay. This method should be called from calculatePay if and when

required.

public static double calculateOverTimePay(int OverTimeHours, double

basePay)

4. A method to display information

public static void displayInfo(String empName, int workingHours, double

totalPay)

Page 4 of 4

Program Name: MyArrayMethods.java [15 Points]

You are provided with the following table which contains the average high temperature data of Gujranwala for

each month of the year 2018.

Month 1 2 3 4 5 6 7 8 9 10 11 12

Average

Temperature

19.1 22.01 27.4 33.7 39.0 40.8 36.1 34.6 35.0 33.0 27.0 21.2

a. Write a method called averageTemperature that accepts an array of type double as

argument; calculates and returns the average temperature. You may use the following method

header:

public static double averageTemperature(double[] temperatures)

b. Write a method called maximumTemperature that accepts an array of type double as argument

and returns the index of maximum temperature from the array.

public static int maximumTemperature(double[] temperatures)

c. Write a method called minimumTemperature
