Explore Standard Candy Vector Operations in C++

Learn how to work with vectors in C++ to manage lists of standard candies like 3 Musketeers, Milky Ways, and Snickers. Practice creating, printing, modifying, and interacting with candy lists using while and for loops. Develop functions to copy and expand candy collections, as well as to sample random candies from the list.

1. Chapter 10 Paul Bodily

2. Few reminders with vectors Always have to remember #include <vector> using namespace std; Also,

3. Example

4. Problem spec: Trick or Treat! 1. Create a vector of strings standardCandyBowl representing standard types of candy: 3 Musketeers, Milky Ways, and Snickers Write a function printVector() to print out the list of strings using a while loop 2.

5. Problem spec: Trick or Treat! 1. Create a vector of strings standardCandyBowl representing standard types of candy: 3 Musketeers, Milky Ways, and Snickers Write a function printVector() to print out the list of strings using a while loop Modify the program to use a for loop instead of a while loop 2. 3.

6. Problem spec: Trick or Treat! 1. Create a vector of strings standardCandyBowl representing standard types of candy: 3 Musketeers, Milky Ways, and Snickers Write a function printVector() to print out the list of strings using a while loop Modify the program to use a for loop instead of a while loop Write a function to create a vector myCandyBowl that starts by copying the vector standardCandyBowl and then prompts the user to add another candies 2. 3. 4.

Create a vector of strings standardCandyBowl representing standard types of candy: 3 Musketeers, Milky Ways, and Snickers Write a function printVector() to print out the list of strings using a while loop Modify the program to use a for loop instead of a while loop Write a function to create a vector myCandyBowl that starts by copying the vector standardCandyBowl and then prompts the user to add another candies Write a function selectRandom() to sample a random string from a vector 2. 3. 4. 5.

10. Example Standard Candies: 0. Milky Way 1. 3 Musketeers 2. Snickers EXAMPLE

11. Example Standard Candies: 0. Milky Way 1. 3 Musketeers 2. Snickers My Candy Bowl: 0. Milky Way 1. 3 Musketeers 2. Snickers 3. Reese's PB Cups

12. Example Standard Candies: 0. Milky Way 1. 3 Musketeers 2. Snickers My Candy Bowl: 0. Milky Way 1. 3 Musketeers 2. Snickers 3. Reese's PB Cups ***** Austin ***** 0. Reese's PB Cups

13. Example Standard Candies: 0. Milky Way 1. 3 Musketeers 2. Snickers My Candy Bowl: 0. Milky Way 1. 3 Musketeers 2. Snickers 3. Reese's PB Cups ***** Austin ***** 0. Reese's PB Cups 1. Snickers 2. 3 Musketeers 3. Reese's PB Cups 4. 3 Musketeers 5. Reese's PB Cups

14. Example Standard Candies: 0. Milky Way 1. 3 Musketeers 2. Snickers My Candy Bowl: 0. Milky Way 1. 3 Musketeers 2. Snickers 3. Reese's PB Cups ***** Austin ***** 0. Reese's PB Cups 1. Snickers 2. 3 Musketeers 3. Reese's PB Cups 4. 3 Musketeers 5. Reese's PB Cups Austin had 3 Reese's PB Cups

15. Example Standard Candies: 0. Milky Way 1. 3 Musketeers 2. Snickers My Candy Bowl: 0. Milky Way 1. 3 Musketeers 2. Snickers 3. Reese's PB Cups ***** Austin ***** 0. Reese's PB Cups 1. Snickers 2. 3 Musketeers 3. Reese's PB Cups 4. 3 Musketeers 5. Reese's PB Cups Austin had 3 Reese's PB Cups Random Dad tax = 0.335223 Austin owes dad 1.00567 Reese's PB Cups

16. Example ... Standard Candies: 0. Milky Way 1. 3 Musketeers 2. Snickers ***** Siena ***** Siena had 1 Reese's PB Cups Random Dad tax = 0.513401 Siena owes dad 0.513401 Reese's PB Cups My Candy Bowl: 0. Milky Way 1. 3 Musketeers 2. Snickers 3. Reese's PB Cups ***** Autumn ***** ... Autumn had 1 Reese's PB Cups Random Dad tax = 0.0163006 Autumn owes dad 0.0163006 Reese's PB Cups ***** Austin ***** 0. Reese's PB Cups 1.

18. Histograms/Bar charts A frequency chart Example: How many trees are 100-150 cm: 4 150-200 cm: 30 200-250 cm: 26 250-300 cm: 50 300-350 cm: 11 A bar chart is like a histogram except x values can be categorical rather than numerical Example: How many candy bars are Almond Joy: 3 Crunch: 3.6 Krackel: 2.1 etc.
