Why isn't this code working? I can't figure it out. It keeps showing a red line under the while (getline(file, console[i])) , price[i] = stof(temp) , getline(cin, str) , getline(fi, temp); ++n . string console[n] , and float price[n] . I included the whole code so you could cut and paste it in the program. I have been using Visual Studio 2019. Here is the instructions for the code.

Fix this program to price video game consoles.Use parallel arrays to input, print, find the most valuable, and sort pricing data.

Console Current Price

Nintendo Entertainment System 57

Sega Genesis 34

Microsoft Xbox 360 58

Sony PlayStation 4 261

Atari 2600 26

Nintendo Game Cube 52

Requirements

1.Read the input file prices.txt into parallel arrays. Fix the program to allow for any number of lines in the input file (up to a certain maximum).The console names have spaces in them, so be sure to use the getline() function.

2.Use a menu-driven program with these choices:

a.Display all console prices

b.Look up the price of a particular console

c.Sort prices in descending order

d.Display the console with the highest price

e.Exit the program

3.Create these functions according to the prototypes:

a.void loadArrays(string[], float[], int &);

b.void showArrays(string[], float[], int);

c.void lookUpPrice(string[], float[], int);

d.void sortPrices(string[], float[], int);

e.void highestPrice(string[], float[], int);

f.int showMenu();// display a menu and return the user's choice

4.Use a loop to allow the user to keep making menu selections until the exit option is chosen.

5.Use the data types which accurately represent the data, and show to two decimal places whenever displaying dollars and cents.

6.Functions must pass parameters and return values as needed, using only local variables.Global variables are not allowed.

7.make any other functions or variables as you see fit.

8.Output must be labeled and easy to read.

9.Use comments to document your program as you see fit.

10.Submit your source code and a screen shot of your program output

Hints for using getline()

The getline() function does two things: reads data from the file (or cin), and returns a Boolean indicating success.When you try to read past the end of file, getline() returns false.Use this as the condition for a while loop.

Mixing the >> operator with getline() is problematic, so use getline() once to read the console name, and again to read the price.Since getline() requires reading into a string, define a temporary string variable for reading the price, then use the stof() function to convert the string to a floating-point type.

For example:

while (getline(file, console[i]))// read in console name

{

string temp;

getline(file, temp);//read price into a temporary string variable

price[i] = stof(temp);//convert string to floating-point

i++;//increment counter

}
