• 2 pts: Attendance(at start and end of lab)
• 7 pts: Participation
• 1 pts: Style(comments, line wraps, variable names)

Collaboration policy:

You will be working in pairs during labs. Pairs will be randomly selected and will be announced by the TA. Each week you will have a new random partner. You will discuss the programs with your partner, but you will still be typing in your own code to show to the TA. You can help each other debug, give plenty of suggestions and hints, **explain** why things work or don't work, etc.

Part 1:

Write a program that generates possible email addresses. The program should read in the users first name, then their middle initial, followed by their last name. It should then output 4 suggestions for email addresses. The 4 suggestions should be determined as follows:

• The first letter of their first name followed by their complete last name.
• Their complete first name followed by the first letter of their last name.
• Their initials followed by the number of characters in their last name.
• Their complete first name followed by the first letter of their last name followed by the total number of characters in their first and last names.

You do not need to save these email addresses in a string object using concatenation. Just output them.

Example 1: (user input is bold and underlined)

    Enter your first name: Kris
    Enter your middle initial: T
    Enter your last name: Miller

    Here are some suggestions for email addresses:

    KMiller
    KrisM
    KTM6
    KrisM10

Example 2:

    Enter your first name: George
    Enter your middle initial: W
    Enter your last name: Bush

    Here are some suggestions for email addresses:

    GBush
    GeorgeB
    GWB4
    GeorgeB10

Part 2:

Write a program that reads in 4 items at a department store, the quantity to be purchased of each item, and the cost for each item. Calculate the price for each item before and after sales tax and then calculate the total amount of the purchase including sales tax. The sales tax is 7.75%. Your output should look like the following example.

Example: (user input is bold and underlined)

Enter item 1: T-shirts
Enter quantity: 5
Enter cost of item: 13.99

Enter item 2: Socks
Enter quantity: 4
Enter cost of item: 4.99

Enter item 3: Shorts
Enter quantity: 2
Enter cost of item: 15.99

Enter item 4: Shoes
Enter quantity: 1
Enter cost of item: 69.99

   Item            Quantity     Cost(Before Tax)  Sales Tax    Total
--------------------------------------------------------------------
1. T-shirts	          5	           69.95       5.42    75.37        
2. Socks                  4                19.96       1.55    21.51
3. Shorts		  2		   31.98       2.48    34.46
4. Shoes                  1		   69.99       5.42    75.41
                                                               -----

Part 3:

Fix all syntax and logic errors in the following program so that it compiles and runs correctly. You should copy-and-paste this code to your file rather than type it.

#include <iostreem>
using namespace std;

int main
{   
   double num1, num2;

   // Get 2 floating-point values from user
   cout << "Enter 2 floating-point values:";
   cin >> num1, num2;

   // Use fixed notation and 2 digits after the decimal for all outputs
   cout << fixed << setprecision(2);

   // Demonstrate arithmetic operators
   cout << "num1 + num2 = " << num1 + num2;
   cout << "num1 - num2 = " << num1 - num2;
   cout << "num1 * num2 = " << num1 * num3;
   cout << "num1 / num2 = " << num1 / num2;
   cout << "num1 % num2 = " << num1 % num2;

   // Output average of inputs
   cout << "\nAverage of num1 and num2 =  
        << (num1 + num2) / 2.0

   return 0;
}
