Please code this in c++

5.19 Farmer's market - files

Get the file name from the user and open it using code. The file has the product name and price/lb in each line.

Until the EOF is reached:

Read the product name from the file

prompt the user for entering the weight of that product. (Points will be taken off if you hard-code the product name inside your code).

Once the user enters the weight(0 if user does not buy that item), calculate the cost of that item by reading the price of that item from the file and multiplying by the weight entered by the user.

Maintain a running total of the cost until all the items have been entered by user.

Once EOF is reached, display the total cost of the purchase

product. txt // contains the following

apple 1.59
orange 0.99
banana 0.69
grapes 2.99

See explaination

Explanation:

#include<iostream>

#include<fstream>

using namespace std;

int main(){

double price, totalPrice = 0, weight;

string product, filename;

cout<<"Enter filename: ";

cin>>filename;

ifstream fin;

fin.open(filename.c_str());

while(fin>>product>>price){

cout<<"Enter weight for "<<product<<": ";

cin>>weight;

totalPrice+=price*weight;

}

cout<<"\nThe total cost of the purchase: $"<<totalPrice<<endl;

return 0;

}

the major difference between the two is the objective and the reward of the game. candy crush has a puzzle theme with the objective of meeting a specific quota of points or objects, you are able to gain access to the next level and compete with peers on the process. on duolingo the objective is rather different, you are given sets of questions for you to answer for you to move to the next level and as for the reward, you are able to learn available language as this is an app developed to teach the user about other languages.
