STEP ONE: stock commission program

Description / Specifications
This program was taken from page 82, Exercise 2-17 in the book Starting out with C++ From Control Structures through Objects by Tony Gaddis. Kathryn bought 750 shares of stock at a price of $35.00 per share. She must pay her stockbroker a 2 percent commission for the transaction. Write a program that calculates and displays the following:
- The amount paid for the stock alone (without the commission)
- The amount of the commission
- The total amount paid (for the stock plus the commission)
Dollar amounts should always display exactly 2 decimal places. In order to do this, you will need to #include<iomanip> at the top of your program (above or below #include<iostream>) and then right after you define your variables type:
cout << setprecision(2) << fixed;
Save this program as lab2a.cpp. Make sure your program compiles and runs like the sample output below.
Sample OutpuT
Amount paid for the stock: $26250.00
Commission paid on the sale: $525.00
Total amount paid for stock: $26775.00

DESCRIPTION / SPECIFICATIONS
This program was taken from page 82, Exercise 2-18 in the book Starting out with C++ From Control Structures through Objects by Tony Gaddis. A soft drink company recently surveyed 16,500 of its customers and found that approximately 15 percent of those surveyed purchase one or more energy drinks per week. Of those customers who purchase energy drinks, approximately 58 percent of them prefer citrus-flavored energy drinks. Write a program that displays the following:
- The approximate number of customers in the survey who purchase one ore more energy drinks per week
- The approximate number of customers in the survey who prefer citrus-flavored energy drinks
You should always end up with a whole person.
Save this program as lab2b.cpp. Make sure your program compiles and runs like the sample output below.
SAMPLE OUTPUT
Num of people who drink more than one a week: 2475
Num of people who drink more than one a week and prefer Citrus flavored: 1436

Description / Specifications
Take the program given to you in ilearn named lab2c_given.cpp. Rename this file lab2c.cpp.
Pat Smith and Kelly Jones are engaged. This program shows the possible last name combinations once they get married (listing Pat first). Extend this program to print the two hyphenated last name options (Smith-Jones, and Jones-Smith). Also make sure to modify the author information in the comment to be yours and your partner’s names
SAMPLE OUTPUT
The yellow highlighted parts are user input and the green highlighted part is what you are adding to the code.
What is the first person’s first name?
Pat
What is the first person’s last name?
Smith
What is the second person’s first name?
Kelly
What is the second person’s last name?
Jones
Here are some common married-couple names:
Pat Smith and Kelly Jones
Pat and Kelly Smith
Pat and Kelly Jones
Pat Smith and Kelly Smith-Jones
Pat Smith and Kelly Jones-Smith
What to Turn In
