Assignment 10.1: Buying More Pastries (10 pts)

Let's alter it to also print a receipt at the bottom of the order.

Each pastry will also now need a price displayed to the user.

Assume each pastry is priced according to the following table:

• Your program should also print out a subtotal for each type of pastry purchased, as well as the final total at the end.

• Note that each price must be displayed to exactly two decimal places.
• Below is an example run of the program (note that user input will vary):

• When your program works identically to the example above, please upload it to Canvas.

Assignment 10.2: Weight in Space (10 pts)

• Remember our class activity where we calculated a user's weight on the moon?
• Let's see if we can expand it to provide more options for the user.
• Instead, we will calculate how the user's weight changes on different planets.
• Open Eclipse and create a project called Planet with a file name planet.cpp.
• Your program should prompt the user to enter his or her weight, as well as the name of a planet.
• Note that the user should be allowed to enter both lower and upper case names of planets.
• Next, you will need a series of if-else if-else statements, like the following:

if (//test for planet name) {

    weight = weight * MERCURY_MULT;

} else if (//test for a second planet name) {

    //statement goes here

}
//rest of else ifs go here

} else {

    //ERROR CHECKING!   

}

• To calculate the user's weight on the planet of his or her choice, you will need to know the conversion rate for each of the planets. The conversion is as follows:

Planet	Multiplier
Mercury	0.38
Venus	0.91
Mars	0.38
Jupiter	2.54
Saturn	1.08
Uranus	0.91
Neptune	1.19
Pluto	0.06

• Note that to avoid magic numbers, you will need to declare a const variable for each of the multipliers above. Your const variables should look like this:

const double MERCURY_MULT = 0.38;

• At the end of the program, you should display the message "You weigh X.X pounds on <Insert Planet Name Here>." (See sample output below)
  
• Important: The output for the weight should only have one number after the decimal point.
  
• Finally, take a moment to make sure your indentation is correct. Your indentation should look like the following

#include <iostream>

#include <iomanip>

using namespace std;

int main() {
     if (test condition) {

         //statements

     } else if {

         //statements

     } else if {

         //statements

     } else {

         //statements

     }
}

• Your program should work identically to the following (except user input may vary):
  

Welcome!

What do you weigh on other planets?

Enter your weight in pounds: 123

Now, select from one of the following planets:

    Mercury

    Venus

    Mars

    Jupiter

    Saturn

    Uranus

    Neptune

    Pluto

Please enter the planet: mercury

You weigh 46.7 lbs on Mercury

• Another example (upper case planet name input):
  

Welcome!

What do you weigh on other planets?

Enter your weight in pounds: 189

Now, select from one of the following planets:

    Mercury

    Venus

    Mars

    Jupiter

    Saturn

    Uranus

    Neptune

    Pluto

Please enter the planet: Neptune

You weigh 224.9 lbs on Neptune

• Alternately, your program should output the following if the user provides an invalid entry:

Welcome!

What do you weigh on other planets?

Enter your weight in pounds: 147

Now, select from one of the following planets:

    Mercury

    Venus

    Mars

    Jupiter

    Saturn

    Uranus

    Neptune

    Pluto

Please enter the planet: Marz

You entered an invalid planet name.

Please rerun the program to try again.
