Overview

The purpose of this task is to gain experience in C++ programming and software development skills. You are expected to write a C++ program to solve each question.

For each question, you need to write the code to display the results which is the same as the sample run. Submit your code in Gradescope to test the program implementation. Also, you will write a short description for each question in the report to analyse your methods and discuss the results with your test cases. The code quality such as naming rules of variables and comments of functions will also be evaluated.

Question 1. Financial application:future investment value (10 marks)

Write a program that reads in investment amount, annual interest rate, and number of years, and displays the future investment value using the following formula:

futureInvestmentValue = investmentAmount x (1 + monthlyInterestRate)^ (numberOfYears x 12)

For example, if you enter amount 1000.56, annual interest rate 4.25%, and number of years 1, the future investment value is $1043.92.

Sample Run

Enter investment amount: 1000.56

Enter annual interest rate in percentage: 4.25

Enter number of years: 1

Accumulated value is $1043.92

Question 2. Science: day of the week (10 marks)

Zeller’s congruence is an algorithm developed by Christian Zeller to calculate the day of the week. The formula is:

where

- h is the day of the week (0: Saturday, 1: Sunday, 2: Monday, 3: Tuesday, 4: Wednesday, 5: Thursday, 6: Friday).

- q is the day of the month.

- m is the month (3: March, 4: April, . . . , 12: December). January and February are counted as months 13 and 14 of the previous year.

- j is year/100

- k is the year of the century (i.e., year % 100)

Note that all divisions in this exercise perform. an integer division.

Write a program that enters a year, month, and day of the month, and displays the name of the day of the week.

Sample Run 1

Enter year (e.g., 2012): 2015 Enter month (1-12): 1 Enter the day of the month (1-31): 25 Day of the week is Sunday

Sample Run 2

Enter year (e.g., 2012): 2012 Enter month (1-12): 5 Enter the day of the month (1-31): 12 Day of the week is Saturday

(Hint: January and February are counted as 13 and 14 in the formula, so you need to convert the user input

1 to 13 and 2 to 14 for the month and change the year to the previous year.)

Question 3. Order three cities (10 marks)

Write a program that enters three cities and displays them in ascending order. City names may contain spaces.

Sample Run

Enter the first city: Shanghai

Enter the second city: Suzhou

Enter the third city: Beijing

The three cities in alphabetical order are Beijing Shanghai Suzhou

Question 4. Check password (10 marks)

Some websites impose certain rules for passwords. Suppose the password rules are as follows:

- A password must have at least eight characters.

- A password must consist of only letters and digits.

- A password must contain at least two digits.

Write a program that enters a password and displays valid password if the rules are followed or invalid password otherwise.

Sample Run

Enter a string for password: DTS102TC valid password！

Enter a string for password: C++ Programming invalid password！

Question 5. Algebra: solve 2 × 2 linear equations (15 marks)

You can use Cramer’s rule to solve the following 2 × 2 system of linear equation:

Write a function with the following header:

void solveEquation(double a, double b, double c, double d, double e, double f, double& x, double& y, bool& isSolvable)

If ad - bc is 0, the equation has no solution and isSolvable should be false. Write a program that enters a, b, c, d, e, and f and displays the result.

If ad - bc is 0, report that “The equation has no solution.”

Sample Run

Enter a, b, c, d, e, f: 9.0 4.0 3.0 -5.0 -6.0 -21.0 x is -2.0 and y is 3.0

Enter a, b, c, d, e, f: 1.0 2.0 2.0 4.0 4.0 5.0 The equation has no solution

Question 6. Financial application: compute the future investment value (15 marks)

(Financial application: compute the future investment value)

Write a function that computes future investment value at a given interest rate for a specified number of years. The future investment is determined using the formula in Question 1.

Use the following function header:

double futureInvestmentValue(double investmentAmount, double monthlyInterestRate, int years)

For example,

futureInvestmentValue(10000, 0.05/12, 5) returns 12833.59.

Write a test program that prompts the user to enter the investment amount (e.g., 1000) and the interest rate (e.g., 9%) and prints a table that displays future value for the years from 1 to 30, as shown below:

Sample Run

The amount invested: 1000 Annual interest rate: 9

Years Future Value

1     1093.81 2     1196.41

...

29    13467.25

30    14730.58

Question 7. Statistics: compute mean and standard deviation (15 marks)

Apply the below formula to compute the standard deviation of n numbers.

To compute deviation with this formula, you have to store the individual numbers using an array, so that they can be used after the mean is obtained.

Your program should contain the following functions:

// Compute the mean of an array of double values double mean(const double x[], int size)

// Compute the deviation of double values

double deviation(const double x[], int size)

Write a test program that enters 10 numbers and displays the mean and deviation, as shown in the following sample run:

Sample Run

Enter ten numbers: 1.9 2.5 3.7 2 1 6 3 4 5 2 The mean is 3.11

The standard deviation is 1.55738

Question 8. Markov matrix (15 marks)

An n by n matrix is called a positive Markov matrix if eachelementis positive and thesumof theelementsin each column is 1. Write the following function to checkwhethera matrix is a Markov matrix.

const int SIZE = 3;

bool isMarkovMatrix(const double m[][SIZE]);

Write a testprogramthat enters a 3 by 3 matrix ofdoublevaluesand testswhetherit is a Markov matrix. Here are sample runs:

Sample Run 1

Enter a 3-by-3 matrix row by row: 0.15 0.875 0.375

0.55 0.005 0.225

0.30 0.12 0.4

It is a Markov matrix

Sample Run 2

Enter a 3-by-3 matrix row by row: 0.95 -0.875 0.375

0.65 0.005 0.225

0.30 0.22 -0.4

It is not a Markov matrix
