The actual formula is :
W = 35.74 + 0.6215t - 35.75 (v0.16) + 0.4275t(v0.16)

Need help using pow function in problem
What I'm trying to do:
1. Attempt to open the file. The filename, c:\\windData.tx t, should be hardcoded into your program. Note the two slash characters in the file name. If the file cannot be opened, display a message and exit the program.
2. From the file read a temperature and a wind speed. Both values should be stored in variables declared as double. The file is a text file.
3. Calculate the wind chill factor... -
woops. I had them there originally, then took them out for some reason. I think i messing around with using string instead of void.
Here's what I need to accomplish:
Your program should include
1. A function named getData( )that gets all of the user input for a round pizza. For a round pizza it will ask for the diameter of the pizza and its price. Each piece of data entered by the user must be validated...Leave a comment:

Thanks for that. However, we haven't even gone through pointers yet, so I need a way to do that referencing without having pointers in it? :)

Price is part of an equation, so I don't think that will work. Here's the whole file:
...Code:#include <iostream> using namespace std; char pizzaType; void getData(int length, int width, int price); void getData(int diameter, int price); double computeUnitCost(int diameter, int price); double computeUnitCost(int length, int width, int price); int main()

Hmm for some reason I put that, and I get:
pizza.cpp
pizza.cpp: In function `int main()':
pizza.cpp:27: warning: unused variable 'diameter'
pizza.cpp:29: error: `diameter' undeclared (first use this function)
pizza.cpp:29: error: (Each undeclared identifier is reported on
And I have:
...Code:int diameter; int price; getData(diameter, price);

How to pass parameter or call a function?
How do I call a function outside of main or use a parameter to pass a reference?
If my function is:
...Code:void getData(int& diameter, int& price) { cout << "Enter in the diameter of the pizza in: " << endl; cin >> diameter; cout << "Enter in the the price of the pizza in: " << endl; cin >> price; } -
Thanks for the help so far! My real problem is knowing how to call and pass parameters correctly. Are the other functions right?
...Code:#include <iostream> using namespace std; char pizzaType; void getData(int length, int width, int price); void getData(int diamter, int price); double computeUnitCost(int diameter, int price); double computeUnitCost(int length, int width,

Need help straightening this noob code
I have trouble knowing how to call the function and passing parameters. Can someone help point out where things need to go? It's a basic program to figure out the cost per inch of pizza of either a round(diameter) pizza or square one.
...Code:using namespace std; char pizzaType; double getData(int length, int width, int price); double getData(int diamter, int price); double computeUnitCost(int diameter,
