Thread: Help with Code (function)

Can some1 help tell me y my function keeps having errors? I want the user to enter 4 price s, total sales each products sale is worth 25% of the sale. I wanna take these 4 products and calculate an average and return the value to the variable slsAvg. Is my function prototype, call, and function that much off?

Code:

double calcAveragefunc(double towers, double monitors, double printers, double desks, double slsAvg)
{
      return slsAvg;
      }
                       
using namespace std;

int main(){
    
    double towers;
    double monitors;
    double printers;
    double desks;
    double totalProductSales;
    double slsAvg;
    
    cout << "Enter towers price: "; 
    cin >> towers;
    cout << "Enter monitors price: ";
    cin>> monitors;
    cout << "Enter printers price: ";
    cin >> printers;
    cout << "Enter desks price: ";
    cin >> desks;
    
    totalProductSales = towers + monitors + printers + desks * 25;
    
    slsAvg = totalProductSales / 4;
    
    return 0;
}
double calcAveragefunc(double towers, double monitors, double printers, double desks, double slsAvg)
{
     return slsAvg;
}

It's late, but what exactly is that *25 for?

a+b+c+d/4 is your average. Or perhaps within your question there's something that I'm missing.

Code:

    void calculate(double a, double b, double c, double d)
     {
     double e=a+b+c+d;
     double pcent=e/4;
     cout<<pcent;
     }

int main()
{
double aa, bb, cc, dd;
    cout<<"enter aa";
    cin>>aa;
    cout<<"enter bb";
    cin>>bb;
    cout<<"enter cc";
    cin>>cc;
    cout<<"enter dd";
    cin>>dd;
calculate(aa,bb,cc,dd);
cin.get();
}
