Error on Xcode "No matching function for call to 'max'"

Question

This is the statement that I'm using but it says that no matching function for call to 'max'

max((used_minutes-Included_Minutes)*extra_charge,0) 

Any help would be appreciated.

EDIT

Code

 int used_minutes; const int Included_Minutes = 300;
 double total_charge, extra_charge;
 cout << "Enter the number of phone call minutes: ";
 cin >> used_minutes;
 cout <<"Number of phone call minutes used - included in the base plan: " << min(used_minutes,Included_Minutes) << endl;
 cout <<"Number of phone call minutes used - not included in the base plan: "<< max(used_minutes-Included_Minutes,0) << endl;
 extra_charge = 0.10;
 cout <<"Cost of excess phone call minutes: $"<<fixed << setprecision(2) << max(used_minutes-Included_Minutes)*extra_charge, 0) <<endl;

Answer 1

max() requires that the first and second arguments are of the same type. extra_charge is a double which results in the first and second arguments having different type. Try:

max((used_minutes-Included_Minutes)*extra_charge,0.0)
