I'm trying to calculate the volume, cost, charge, and profit by defining a function and having a function call in the main. I have defined my functions but I guess I don't know how to put the function call in the main, my answers are coming out weird. Can anyone help my with this?
Code:
#include <iostream>using namespace std;
double cal_vol (double l, double w, double h) //volume function
{
double V;
V = l * w * h;
return V;
}
double cal_cost (double V)//cost function
{
double C;
C = V * 0.23;
return C;
}
double cal_charge (double V)// charge function
{
double D;
D = V * 0.5;
return D;
}
double cal_profit (double D, double C)//profit function
{
double P;
P = D - C;
return P;
}
main()
{
int l, w, h;
double cal_vol, cal_cost, cal_charge, cal_profit;
cout << "Enter crate length : ";
cin >> l;
cout << "Enter crate width : ";
cin >> w;
cout << "Enter crate height : ";
cin >> h;
cout << "The crate's volume is " << cal_vol << endl;
cout << "The crate's cost is " << cal_cost << endl;
cout << "The customer's charge is " << cal_charge << endl;
cout << "The profit is " << cal_profit << endl;
system("pause");
}
