### Sales and Profit Program

Hello I need help with my c++ program,
A well-regarded manufacturer of widgets has been losing 4% of its sales each year. The company’s annual profit is 10% of sales. This year, the company has had \$10 million in sales and a profit of \$1million. Determine the expected sales and profit for the next 10 years. Your program should produce and display in the following form:
The output is this,
SALES AND PROFIT PROJECTION
YEAR EXPECTED SALES PROJECTED PROFIT
1 \$10000000.00 \$1000000.00
2 \$ 9600000.00 \$ 960000.00
3 - -
- - -
10 - -
Totals: \$ - \$ -

This is my code:

#include <iostream>
#include <iomanip>

using namespace std;

int main()
{
float sales = 0.04;
float profit = 0.10;
float exSales = 10000000.00;
float finalSales;
float proProfit;
int year;
float totalSales, totalProfit;

cout << "\tSALES AND PROFIT PROJECTION";
cout << "\nYEAR \t\tEXPECTED SALES \t\tPROJECTED PROFIT";

for (year=1; year<=10; year++)
{
finalSales = exSales * profit;
proProfit = exSales * sales;
cout << "\n" <<year <<"\t\t"<< setw(3)<< fixed << setprecision(2)<< finalSales <<"\t\t\t"<< setw(3) << fixed << setprecision(2) <<proProfit;
}

cout << "\n---------------------------------------------------------";
totalSales += finalSales;
totalProfit += proProfit;
cout << "\nTotal:" <<"\t"<< setw(3)<< fixed << setprecision(2)<< totalSales <<"\t"<< setw(3) << fixed << setprecision(2) <<totalProfit;

return 0;
}
I did an ugly code I know, but my teacher doesn't explain anything she just gave us notes and never explain anything

My output:
SALES AND PROFIT PROJECTION
YEAR EXPECTED SALES PROJECTED PROFIT
1 1000000.00 400000.00
2 1000000.00 400000.00
3 1000000.00 400000.00
4 1000000.00 400000.00
5 1000000.00 400000.00
6 1000000.00 400000.00
7 1000000.00 400000.00
8 1000000.00 400000.00
9 1000000.00 400000.00
10 1000000.00 400000.00
---------------------------------------------------------
Total: 409284524881555530032060431335424.00 400000.00

When posting code, please use code tags so that the code is readable

 ``` [code] // code goes here [/code] ```

You need to initialise variables when they are defined. totalSales and totalProfit aren't and have unknown initial values. Set them to 0. Also I think you need to keep the runing tally of ttalSales and totalProfit within the for loop. Perhaps:

 ``123456789101112131415161718192021222324252627`` ``````#include #include using namespace std; int main() { float sales = 0.04; float profit = 0.10; float exSales = 10000000.00; float totalSales = 0, totalProfit = 0; cout << "\tSALES AND PROFIT PROJECTION"; cout << "\nYEAR \t\tEXPECTED SALES \t\tPROJECTED PROFIT"; for (int year = 1; year <= 10; year++) { float finalSales = exSales * profit; float proProfit = exSales * sales; totalSales += finalSales; totalProfit += proProfit; cout << "\n" << year << "\t\t" << setw(3) << fixed << setprecision(2) << finalSales << "\t\t\t" << setw(3) << fixed << setprecision(2) << proProfit; } cout << "\n---------------------------------------------------------"; cout << "\nTotal:" << "\t\t" << setw(3) << fixed << setprecision(2) << totalSales << "\t\t\t" << setw(3) << fixed << setprecision(2) << totalProfit; }``````

 ``` SALES AND PROFIT PROJECTION YEAR EXPECTED SALES PROJECTED PROFIT 1 1000000.00 400000.00 2 1000000.00 400000.00 3 1000000.00 400000.00 4 1000000.00 400000.00 5 1000000.00 400000.00 6 1000000.00 400000.00 7 1000000.00 400000.00 8 1000000.00 400000.00 9 1000000.00 400000.00 10 1000000.00 400000.00 --------------------------------------------------------- Total: 10000000.00 4000000.00 ```

Oh okay my bad, but the projected profit should be 10% of the expected sales, and expected sales on year 2 should be 9600000.00 applying the deduction of 4% to the 10 million sales and so for the following year.
Sorry. My bad. I didn't read the description - just looked at the code!

Perhaps something like:

 ``123456789101112131415161718192021222324252627282930`` ``````#include #include using namespace std; int main() { const double sales = 0.04; const double profit = 0.10; double exSales = 10000000.00; double totalSales = 0, totalProfit = 0; cout << "\tSALES AND PROFIT PROJECTION"; cout << "\nYEAR \t\tEXPECTED SALES \t\tPROJECTED PROFIT"; for (int year = 1; year <= 10; ++year) { double proProfit = exSales * profit; totalSales += exSales; totalProfit += proProfit; cout << "\n" << year << "\t\t" << setw(3) << fixed << setprecision(2) << exSales << "\t\t\t" << setw(3) << fixed << setprecision(2) << proProfit; exSales -= exSales * sales; } cout << "\n---------------------------------------------------------"; cout << "\nTotal:" << "\t\t" << setw(3) << fixed << setprecision(2) << totalSales << "\t\t\t" << setw(3) << fixed << setprecision(2) << totalProfit; }``````

 ``` SALES AND PROFIT PROJECTION YEAR EXPECTED SALES PROJECTED PROFIT 1 10000000.00 1000000.00 2 9600000.00 960000.00 3 9216000.00 921600.00 4 8847360.00 884736.00 5 8493465.60 849346.56 6 8153726.98 815372.70 7 7827577.90 782757.79 8 7514474.78 751447.48 9 7213895.79 721389.58 10 6925339.96 692534.00 --------------------------------------------------------- Total: 83791841.00 8379184.10 ```
