Sam and Ella's Delicatessen wants you to write a program to take orders from the Internet. Your program asks for the item, its price, and if overnight shipping is wanted. Regular shipping for items under $10 is $2.00; for items $10 or more shipping is $3.00. For overnight delivery add $5.00.
Enter the item: Tuna Salad Enter the price: 450 Overnight delivery (0==no, 1==yes) 1 Invoice: Tuna Salad 4.50 shipping 7.00 total 11.50

The maximum possible efficiency of a steam engine depends on the temperature of the steam in the boiler and the temperature of the outside air:
efficiency = 1 - Tair / Tsteam
Tair is the air temperature
Tsteam is the steam temperature.
The temperatures are give in degrees above absolute zero.
Normal air temperature is about 300oK.
Boiling is 373oK.
Write a program that asks the user for the air temperature
and the steam temperature and writes out the
maximum possible efficiency of a steam engine.
if the steam temperature is less than 373oK
there is no steam, so the efficiency is zero.
Use integer or floating point input, but do the calculations in floating point.Click here to go back to the main menu.
A microwave oven manufacturer recommends that when heating two items, add 50% to the heating time, and when heating three items double the heating time. Heating more than three items at once is not recommended.
Write a program that asks the user for the number of items and the single-item heating time. The program then writes out the recommended heating time.
Hint: do this with four successive single-branch if statements each of which tests for one of the four cases: 1 item, 2 items, 3 items, more than three items. Look at the sports car purchase program in the chapter to see how to do this, if you are stuck.Click here to go back to the main menu.
In a new role-playing fantasy game players must design their character by picking a point value for each of three characteristics:
