ok, so I made those changes and I am still getting the same error c2660...function does not take two arguments...

The function protoype dose not match the function definition:
1
2
3
4
5
6
7
8
9
10
11
 
//function prototypes
double getMiles();
double getNumGallons();
double calcMpg();
...
//Does not match prototype!
double calcMpg(double mil, double gal)
{

	return mil/gal;
}

Change your function prototype as:
1
2
3
4
5
6
7
8
9
10
11
 
//function prototypes
double getMiles();
double getNumGallons();
double calcMpg(double mil, double gal);
...
//Does match prototype!
double calcMpg(double mil, double gal)
{

	return mil/gal;
}


call the function as:
1
2
3
4
5
6
 
    //enter input items
    miles = getMiles();
    gallons = getNumGallons();

    //calculate miles per gallon
    milesPerGal = calcMpg(miles, gallons);


or
milesPerGal = calcMpg( getMiles(), getNumGallons() );
