public class Student {
private String name;
private int age;
public Student(){
name = "";
age= 0;
}
public Student(String initName){
name = initName;
age = 0;
}
public String getName() {
return name;
}
public void setAge(int anAge) {

Need to check if File is successfully opened? C++
It works when I input the right txt file. But, it keeps stating, File successfully open." even I put in a non-existing file.
Here are the specifications:
Develop a functional flowchart and then write a C++ program to solve the following problem.
Create a text file named first.txt and write your first name in the file. You will be reading the name of the file from the keyboard as a string, using the string class. Your program will also read your first name from the keyboard. The process of the file creation (name of the file, mode for opening the file, and testing the open success is done in a user-defined function. The function communicates the status of file open to the calling function).
Here is what I have:
#include<string>
#include <iostream>
#include <fstream>
#include <cstdlib>
using namespace std;
int main() {
string file; //This is a declaration for a file name
string firstname;
ofstream myfile;
cout << "Please enter the file name of your
first name:";
cin >> file;
myfile.open(file);
if (myfile.is_open())
{
cout << "\nFile successfully
open.\n";
}
else
{
cout << "Error opening
file";
}
cout << "Please enter your first name:";
//asks the user to input first name
cin >> firstname; //user inputs first name
myfile << firstname;
myfile.close(); //closes the file

For this assignment you will create a set of simple classes that model a cookbook. The cookbook will consist of set or recipes. Each recipe will consist of a set of ingredients and instructions. Your submission will consist of the below three classes and a test driver (the only class with a main()) that exercises the functionality of your system.
You will need to implement the following classes based on the description of their attributes and operations:

What discount rate is appropriate for finding the value of Artforever.com? Write a few paragraphs giving your answer and clearly explaining your reasoning and computations; show detailed computations in your Excel spreadsheet labeled Exhibit 1.
Cost of Debt = 6.2%
After tax rate - CoD = 6.2%*(1-tax rate) = 6.2% * (1-40%) = 3.72%
Considering the Market return, Rm = 8%
Risk-free rate, Rf = 2.5% (30 yr Treasury bond YTM)
Considering industry beta = 1.5
Cost of equity = Rf + beta*(Rm - Rf) = 8% + 1.5*(8% - 2.5%) = 10.75%
Artforever's debt-to-value ratio = 15%.
Hence Equity value would be 85% of V as D+E=V.
WACC/Discounting rate to be used would be = (D/E)*CoD + (E/V)*CoE
= 9.6955% = 9.7%

When you cough, your windpipe contracts. The speed, v(r), with which you expel air through your windpipe, depends in the radius, r, of your windpipe. If a is normal (rest) radius of your windpipe, then for 0<r<a. The speed is given by: v(r)=k(a-r)r^2 where k is a positive constant. For an individual, assume a to be constant. a. Find all critical points of v(r). b. what value of r minimizes the speed? Explain briefly using the second derivative test. c. What value of r maximizes the speed, and what is this maximum speed? explain briefly using the first derivative test. d. Consider two individuals, Jay and Dee. Jay's value of a is larger than Dee's value of a. How would Jay's maximum windpipe velocity compare to that of Dee? Explain briefly.

Jack is riding his bicycle from home to LeConte College with a velocity given by v(t)= -t^4 + 4-t^3 - 500t^2 +2000t in feet away from his house per minute and where t is in minutes. If it takes jack 20 minutes to get to LeConte College, find the following:
a.) Estimation of S (integral) upper 20, lower 0: v(t)dt using left-hand sums with n=2 subdivisions. Why is this a bad estimate?
b.)Estimation of S (integral) upper 20, lower 0, v(t)dt using right hand sums with n=5 subdivisions. What does this number represent an estimate of?
c.) Find the exact distance Jack traveled by integration (assume jack is 0 feet from his house at time = 0)(include units).

(8pts) A hot air balloon moves up at constant speed v = 20.0 m/s. When the balloon is 20.0 meter above the ground, a cup of lemonade falls out of the balloon. And the balloon continues to move up at a constant speed v = 20.0 m/s. Ignore the air resistance.(a)Describe the motion of the lemonade cup as relative to the ground.(b)Describe the motion of the lemonade cup as relative to the balloon. (c)On the same diagram,plot thev-t graph of the balloon and the v-t diagram of the lemonade cup as relative to the ground. Choose upward as the positive direction, and t=0 when the cup starts to fall out of the balloon.(d)How long does it take for the cup to fall tothe ground?(bonus 1pt) What is the distance between the cup and balloon 1 seconds after the cupis dropped?
