Thread: IF Statements ?

I am having a difficult time making it work, some expertise or hints.


Retail Price = 99.00 and for each units sold you get a discount. This program should calculate quantity discounts:

Input Validation: units > 0






#include <iostream>
#include <iomanip>
using namespace std;

int main()
{
float units;
float total;
float discount;
cons float price = 99.00

cout << fixed << showpoint << setprecision (2);

cout << "how many units sold?";
cin >> units;

if ( units >= 10 && units >= 19)
discount = .20;

else if ( units >= 20 && units <= 49)
discount = .30;

else if ( units >= 50 && units <= 99)
discount = .40;

else if ( units >= 100)
discount = .50;

total = (units * price ) - discount;

cout << "The total sales: " << total << endl;

return 0;
}

Code:

units >= 10 && units >= 19

shouldnt this be

Code:

units >= 10 && units <= 19

should be: const float price = 99.;

what exactly is the problem, try RoD's fix; if that doesn't help, explain what you're expecting and what it doesn't do. is it not outputting the right amount? etc.etc. ?
