Program Specifications. Write a program to calculate the cost of hosting three pizza parties on Friday, Saturday and Sunday. Read from input the number of people attending, the average number of slices per person and the cost of one pizza. Dollar values are output with two decimal points, which can be achieved by executing cout << fixed << setprecision(2); once before all other cout statements. Step 1. Read from input the number of people (int), average slices per person (double) and cost of one pizza (double). Calculate the number of whole pizzas needed (8 slices per pizza). There will likely be leftovers for breakfast. Hint: Use the ceil() function found in the cmath library to round up to the nearest whole number and convert to an integer. Ex: If the input is: 10 2.6 10.50

Program Specifications. Write a program to calculate the cost of hosting three pizza parties on Friday, Saturday and Sunday. Read from input the number of people attending, the average number of slices per person and the cost of one pizza. Dollar values are output with two decimal points, which can be achieved by executing cout << fixed << setprecision(2); once before all other cout statements.

Step 1. Read from input the number of people (int), average slices per person (double) and cost of one pizza (double). Calculate the number of whole pizzas needed (8 slices per pizza). There will likely be leftovers for breakfast. Hint: Use the ceil() function found in the cmath library to round up to the nearest whole number and convert to an integer.
Ex: If the input is:

10 2.6 10.50

The output is:

Friday Night Party

4 Pizzas: $42.00

Step 2. Calculate and output the sales tax (7%). Calculate and output the delivery charge (20% of cost including tax). 
Ex: If the input is:

10 2.6 10.50

The output is:

Friday Night Party

4 Pizzas: $42.00

Tax: $2.94

Delivery: $8.99

Step 3. Calculate and output the total including pizza, tax and delivery. 
Ex: If the input is:

10 2.6 10.50

The output is:

Friday Night Party

4 Pizzas: $42.00

Tax: $2.94

Delivery: $8.99

Total: $53.93

Step 4. Repeat steps 1 - 3 with additional inputs for Saturday night (one order per line). Maintain and output a separate total for both parties.
Ex: If the input is:

9 2.5 10.95

14 3.2 14.95

The output is:

Friday Night Party

3 Pizzas: $32.85

Tax: $2.30

Delivery: $7.03

Total: $42.18

Saturday Night Party

6 Pizzas: $89.70

Tax: $6.28

Delivery: $19.20
Total: $115.17

Weekend Total: $157.35

Step 5. Repeat steps 1 - 3 with additional inputs for Sunday night (one order per line). Maintain and output a total for all parties. 
Ex: If the input is:

6 2.8 10.95

22 2.1 12.95 1

2 1.8 14.95

The output is:

Friday Night Party

3 Pizzas: $32.85

Tax: $2.30

Delivery: $7.03

Total: $42.18

Saturday Night Party

6 Pizzas: $77.70

Tax: $5.44

Delivery: $16.63

Total: $99.77
