Write a program that reads a string from the user, and creates another string with the letters from in reversed order. You should do this using string concatenation and loops. Do not use any method from Java that does the work for you. The reverse string must be built. Do not just print the letters in reversed order. Instead, concatenate them in a string.

--- Sample run:
This program will create a string with letters in reversed order.
Enter a string: banana
The reversed string is: ananab
Bye

--- Sample run:
This program will create a string with letters in reversed order.
Enter a string: what the heck
The reversed string is: kceh eht tahw
Bye

Variable Growth Valuation Model Given:

Most recent annual cash flow (CFo) $1,000

Stage 1 annual growth rate (gt) 0.15

Stage 2 annual growth rate (gm) 0.05

Duration of stage 1 growth (years) 3

Required return (k) 0.10

Steps in solution:

1) Estimate future cash flows for the duration of the stage 1 growth period:

CF(0) = given $1,000

CF(1) = CF(0) * (1+gt) $1,150

CF(2) = CF(1) * (1+gt) $1,323

CF(3) = CF(2) * (1+gt) $1,521

2) Use EXCEL's built-in NPV function to find the present value of these cash flows.

RATE 0.10

NPV (rate, CF1:CF3) $3,281.09

3) Use the constant growth formula to estimate the value of the firm at the end of the rapid growth period (V3) where:

CF4 = CF3 (1+gm)

CF4 = $1,597

V3 = $1,597 / (0.10-0.05)

Ve = $31,938

4) Use EXCEL's built-in PV function to find the present value of the amount determined in step 3.

FV $31,938

RATE 0.10

NPER 3

PV ($23,996)

(You may ignore the negative sign for this answer. Recall that EXCEL mandates that the amounts entered for PV and FV must have opposite signs.)

5) Add the amounts found in step 2 (the PV of the rapid growth cash flows ) and step 4 (the PV of the normal growth cash flows).

PV of rapid growth cash flows $3,281

PV of normal growth cash flows $23,996

value of the firm $27,277

// function to determine if a token
vector is_token(const string& s) {
}

int main() {
// make this into a loop such that, like a terminal, input is accepted until the user hits CTRL+d
string str;
cout<<">";
getline(cin, str);

//vector to store the strings or characters returned by is_token() function
vector tokens;

tokens = is_token(str);
}

Modify the main() function to loop until the user exits (e.g. by pressing CTRL+d).

Write a function named is_token() that accepts a string of user input and determines what is a token (see below for token determination rules).
The function must return the separated tokens.

Determining if something is a token:

1. Whitespace (space, tab, etc) ends a token and is skipped unless it is in quotes (see below). You will find the function int isspace(char) useful for detecting whitespace characters.
2. Some characters are considered special tokens: | ; < > &. When one of these characters is encountered, the token being built is completed and a new token consisting of the character is created.
3. The character \ is a special character, i.e. an escape character. The next character will be part (or the start) of a token.
4. Items between single or double quotes are treated as parts of the current token.
5. Characters that do not meet the above rules are added on to the current token being built.

Some examples to test your output:

Input: > we\'ll do some "crazy \"air quotes\""
Output (tokens separated by commas): we'll, do, some, crazy "air quotes"

Input: > ls | sort >sorted_files.txt
Output (tokens separated by commas): ls, |, sort, >, sorted_files.txt

Input: > "now\;is"
Output: now;is

An electric utility company is considering construction of a new power facility in Albuquerque, New Mexico. Construction of the plant would cost $275 millioneach year for five years. Expected annual net cash flows are $85 million each year for five years.

Power from the facility would be sold in the Albuquerque and Santa Fe areas, where it is badly needed. The firm has received a permit, so the plant would be legal as currently proposed, but air pollution would be an issue with the new facility.

To alleviate the environmental concerns the company could spend an additional $50 millionwhen the plant is built. The additional funds cover the costs of special equipment designed to minimize the air pollution. At this time, the special pollution-abatement equipment is not required by law. If the firm adds the environmental protections to the facility, the expected annual net cash flows are $90 million for five years.

Unemployment rates are high in the area Where the plant would be built. The plant would provide about 500 new, well-paying jobs.

The risk-adjusted WACC for this project is 15%. As an employee of the utility company, you have been tasked with analyzing the project. You are to make your recommendations to the company’s Board of Directors in a memo.

1. Calculate the NPV, IRR and regular Payback period for this project (with and without the environmental protection equipment).
2. What is your recommendation for the utility company? Provide support for your responses.
3. What additional qualitative/quantitative factors should be considered in accepting or rejecting both versions of this project? The factors might include job creation, salvage value, project life, discount rate (WACC) etc.

Write a C++ program to calculate the time to drain a cylindrical water tank for an initial water height ranging from 1 to 10 feet (specifically for 1, 2, 4, 6, 8, and 10 ft). The tank has a radius (rt) of 2 feet and the drain radius (rd) is 0.3 inch. The gravitational constant (g) is 32.2 feet/sec².

The formula for time to drain the tank is

time=(rtrd)2h/vavg

where, average velocity, vavg=0.5(2gh).5

In your program, assign the values to the variables rt, rd, and g. Prompt user to enter the value of h. The program should calculate the value of vavg, and then display time in hours.

Using MS Visual Studio, create a project folder called tank and a source code file tank.cpp.

Use the function pow() in the formulas and NOT sqrt().

Set up the output statements (cout) such that the one line display looks like the following:

Initial water height (ft.) = 1; Time to drain (hrs.) = 0.44

STEP 1: Analyze the Problem –

There is only one required output (time in hour of data type double) and one input (initial water height in ft of data type int). All intermediate variables will be assigned a data type of double.

STEP 2: Develop a Solution –

Pseudo code is shown below.

Convert all input data to the same unit (ft)

Display a prompt to enter initial height of water

Read a value for the height

Calculate average velocity, using the given formulas

Display the calculated time

Hand calculation for h = 1 ft, rt = 2 ft, rd = 0.3 inch, and g = 32.2 ft/sec²:

time = ?

STEP 3: Code the Solution -

You can start the program as shown below:

// Filename:

// C++ program to calculate time to drain water tank

// Written by: Your Name   ON: Date

#include <iostream>

#include <iomanip>

#include <cmath>

using namespace std;

int main()

{

     int h;

     double rt = 2.0, rd = 0.3, g = 32.2;

     double vavg, time;

// Input initial water height (h)

//---

// Set output formats

     cout << setiosflags(ios::fixed)

           << setiosflags(ios::showpoint)

           << setprecision(2);// Calculate average velocity in ft/hr

//---

// Calculate time in hrs to drain

// NOTE: The function pow(double a, int n) returns aⁿ

//---

// Display results in the specified format

//---

     return 0;

}

STEP 4: Test and Correct the Program -

If the program shows the correct output, copy and paste the output into MS Word. Also copy and paste the source code to the word processor as well. To copy the display window contents, click on the small black box in the upper left corner, select Edit -> Select All, then click again on the box and select Edit -> Copy.

Test the code by changing initial heights to 2, 4, 6, 8, and 10 feet.

You are doing an internship with Macy’s and are tasked with forecasting sales so that you can make inventory orders. You have weekly sales data for men’s dress shirts in your store from each of the past six weeks. You decide to try both a 3-period moving average and exponential smoothing with λ = 0.7 to see which model is more accurate and then use that one to make forecasts. The sales data is shown below.

What is the calculated MSE for the exponential smoothing method? Round intermediate calculations and final answer to 4 decimals.

What is the calculated MSE using the 3-period moving average? Round intermediate calculations and final answer to 4 decimals.
