Question
Opening Files and Performing File Input
Summary
In this lab, you open a file and read input from that file in a prewritten C++
Instructions
- Ensure the source code file named Flowers.cpp is open in the code editor.
- Declare the variables you will need.
- Write the C++ statements that will open the input file flowers.dat for reading.
- Write a while loop to read the input until EOF is reached.
- In the body of the loop, print the name of each flower and where it can be grown (sun or shade).
- Execute the program by clicking the Run button at the bottom of the screen.
Use Given Files
File #1: Flowers.cpp
// Flowers.cpp - This program reads names of flowers and whether they are grown in shade or sun from an input
// file and prints the information to the user's screen.
// Input: flowers.dat.
// Output: Names of flowers and the words sun or shade.
#include <fstream>
#include <iostream>
#include <string>
using namespace std;
int main()
{
// Declare variables here
// Open input file
// Write while loop that reads records from file.
fin >> flowerName;
// Print flower name using the following format
//cout << var << " grows in the " << var2 << endl;
fin.close();
return 0;
} // End of main function

The credit plan at TidBit Computer Store specifies a 10% down payment and an annual interest rate of 12%. Monthly payments are 5% of the listed purchase price, minus the down payment. Write a program that takes the purchase price as input. The program should display a table, with appropriate headers, of a payment schedule for the lifetime of the loan. Each row of the table should contain the following items: The month number (beginning with 1) The current total balance owed The interest owed for that month The amount of principal owed for that month The payment for that month The balance remaining after payment The amount of interest for a month is equal to balance × rate / 12. The amount of principal for a month is equal to the monthly payment minus the interest owed. An example of the program input and output is shown below: Enter the puchase price: 200 (SEE IMAGE FOR PURCHASE PRICE CHART) Results you should get: Input: 200 Output: Purchase price: 200…arrow_forward

The information is stored in a text file called course.txt inside of the data/ folder. The format of the file is as follows: Lines 1: course ratingLines 2: slope ratingLines 3: course par Your goal is to create a utility which takes a golfer's handicap, course rating, slope rating, and course par, as standard input (keyboard), and prints the golfer's course handicap. The golfer's course handicap should be expressed as a floating point number.
