2D array function calculating sales

[cyfuz]

Hi all,
I'm having trouble figuring out how to calculate the sales for each individual year. Right now, the loop is performing a serial calculation, adding years 0, 1, and 2. How could I separate the calculated sales for that given year?

Here's the code:

void calculateAndDisplayTotalSales(float monthlySales[12][3], const unsigned int 
		numberOfRows, const unsigned int numberOfColumns)
{
	double totalYearlySales = 0.0;
	for (int year = 0; year < YEARS; year++)
	{
		for (int month = 0; month < MONTHS; month++)
		{
			totalYearlySales += monthlySales[month][year];
		}
		cout << "Year " << year << " sales were $";
		cout.setf(ios_base::fixed, ios_base::floatfield);
		cout << setprecision(2) << totalYearlySales << "\n"; 
	}
	cout << "\nThe total for all three years was $" << totalYearlySales;
	cout << endl << endl;
	return;
}

Would I need to declare separate variables to hold the calculated values for a given year?

try to use structures in this... you will find solution...

Hello Guys,

I think you also know about switch case.Use it.

void calculateAndDisplayTotalSales(float monthlySales[12][3], const unsigned int
numberOfRows, const unsigned int numberOfColumns)
{
//double totalYearlySales = 0.0;
for (int year = 0; year < YEARS; year++)
{
double totalYearlySales = 0.0;//correction


for (int month = 0; month < MONTHS; month++)
{
totalYearlySales += monthlySales[month][year];
}
cout << "Year " << year << " sales were $";
cout.setf(ios_base::fixed, ios_base::floatfield);
cout << setprecision(2) << totalYearlySales << "\n";
}
cout << "\nThe total for all three years was $" << totalYearlySales;
cout << endl << endl;
return;
}
