Question

This question has been answered before, but please understand that the display has to be exactly like the one I have on here. Please read carefully and try to help me achieve that display (PLEASE READ THE OUTCOME SECTION AND TRY TO MAKE IT EXACT TO THAT):

Next you will read in the number of shares of stock, a stock purchase price, and a stock sale price. The number of shares will always be an integer value.

With this data calculate the total amount required to purchase the stock. You also need to calculate the commission that has to be paid to the stockbroker. The stockbroker commission will be 3.5% of the amount required to purchase the stock.

Note: the commission percentage must be put into a const double variable that you will use in your calculations. The numeric variables in your program need to be of type double.

Output the name of the company, the cost of a share of stock, the total amount required to pay for the stock (not including the commission), the commission, and the total cost of the stock (including the commission).

Next calculate the amount of income you will get when you sell the stock for the stock sales price. You also need to calculate the cost of the commission to the stockbroker for the sale of the stock. Again this will be 3.5% of the money you get for selling the stock.

Output the price of one share of stock, the amount of money you get from the sale (before the commission is paid), the amount of the commission, and the amount of money you get from the sale after you have paid the commission to the stockbroker. All of the money amounts should be output in a fixed format with two digits to the right of the decimal point.

Final calculate the difference between what you paid for the stock (including the commission), and what you received when you sold the stock (less the commission). This number will be negative if you have lost money.

Here is some sample input data:

Acme Software, Inc.
1000
45.50
56.90

The output from the above input will be:

Company: Acme Software, Inc.
Shares: 1000

Purchase/share: $45.50
Cost of stock: $45500.00
Cost of commission: $1592.50
Total cost: $47092.50

Sale/share: $56.90 
Income from stock: $56900.00
Cost of commission: $1991.50
Total income: $54908.50

Gain or loss: $7816.00

Failure to follow the requirements for lab lessons can result in deductions to your points, even if you pass the validation tests. Logic errors, where you are not actually implementing the correct behavior, can result in reductions even if the test cases happen to return valid answers. This will be true for this and all future lab lessons.

Expected output

There are five tests. Each test will have a new set of input data. You must match, exactly, the expected output.

You will get yellow highlighted text when you run the tests if your output is not what is expected. This can be because you are not getting the correct result. It could also be because your formatting does not match what is required. The checking that zyBooks does is very exacting and you must match it exactly. More information about what the yellow highlighting means can be found in course "How to use zyBooks" - especially section "1.4 zyLab basics".

Finally, do not include a system("pause"); statement in your program. This will cause your verification steps to fail.

Note: that the system("pause"); command runs the pause command on the computer where the program is running. The pausecommand is a Windows command. Your program will be run on a server in the cloud. The cloud server may be running a different operating system (such as Linux).

Answer 1

Dear student,

Program:

#include <iostream>
#include<string>
#include<iomanip>
#include<math.h>
using namespace std;

int main()
{
char cname[50];
const double comm = 3.5;
int shares;
double purchase, sale;
double cost, tc, c_c;
double income, ti, i_c, diff;
cin.get(cname, 100);
cin>>shares;
cin>>purchase;
cin>>sale;
cout<<endl;
  
cost = purchase * shares;
c_c = (comm * cost)/100;
tc = cost + c_c;
  
income = sale * shares;
i_c = (comm * income)/100;
ti = income - i_c;
  
diff = ti - tc;
cout<<"Company: "<<cname<<endl;
cout<<"Shares: "<<shares<<endl;
  
cout<< fixed << setprecision(2);
  
cout<<"\nPurchase/share: $"<<purchase << setprecision(2) <<fixed <<endl;
cout<<"Cost of stock: $"<<cost<<setprecision(2) <<fixed <<endl;
cout<<"Cost of commission: $"<<c_c<<setprecision(2) <<fixed <<endl;
cout<<"Total cost: $"<<tc<<setprecision(2) <<fixed <<endl;

cout<<"\nSale/share: $"<<sale<<setprecision(2) <<fixed <<endl;
cout<<"Income from stock: $"<<income<<setprecision(2) <<fixed <<endl;
cout<<"Cost of commission: $"<<i_c<<setprecision(2) <<fixed <<endl;
cout<<"Total income: $"<<ti<<setprecision(2) <<fixed <<endl;
  
/* if you want to print gain or loss along with the cost
if(diff > 0)
cout<< "\nGain or loss: $"<<diff<<" loss"<<endl;
else
cout<< "\nGain or loss: $"<<fabs(diff)<<" gain"<<endl; */
cout<<"\nGain or loss: $"<<diff<<endl;
return 0;
}

Output:

Thank you, All the best.
