### Candy bar calculations

```//DISPLAY 2.1 A C++ Program
#include <iostream>

int number_of_bars;
double one_weight, total_weight;

cout << "Enter the number of candy bars in a package\n";
cout << "and the weight in ounces of one candy bar.\n";
cout << "Then press return.\n";
cin >> number_of_bars;
cin >> one_weight;

total_weight = one_weight * number_of_bars;

cout << number_of_bars << " candy bars\n";
cout << one_weight << " ounces each\n";
cout << "Total weight is " << total_weight << "ounces.\n";

cout << "Try another brand.\n";
cout << "Enter the number of candy bars in a package\n";
cout << "and the weight in ounces of one candy bar.\n";
cout << "Then press return.\n";
cin >> number_of_bars;
cin >> one_weight;
total_weight = one_weight * number_of_bars;

cout << number_of_bars << " candy bars\n";

### Payroll calculations

```//DISPLAY 2.7 An if-else Statement
#include <iostream>
using namespace std;
int main( )
{
int hours;
double gross_pay, rate;

cout << "Enter the hourly rate of pay: \$";
cin >> rate;
cout << "Enter the number of hours worked,\n"
<< "rounded to a whole number of hours: ";
cin >> hours;

if (hours > 40)
gross_pay = rate*40 + 1.5*rate*(hours - 40);
else
gross_pay = rate*hours;

cout.setf(ios::fixed);
cout.setf(ios::showpoint);
cout.precision(2);

cout << "Hours = " << hours << endl;
cout << "Hourly pay rate = \$" << rate << endl;
cout << "Gross pay = \$" << gross_pay << endl;
system("pause");
return 0;
}```
