Chapter 8, Problem 2PP

(Data processing) a. Store the following data in a file, or use the numbers.dat file provided on this book’s Web site.

5 96 87 78 93 21 4 92 82 85 87 6 72 69 85 75 81 73

b. Write a C++ program to calculate and display the average of each group of numbers in the file created in Exercise 2a. The data is arranged in the file so that each group of numbers is preceded by the number of data items in the group. Therefore, the first number in the file, 5, indicates that the next five numbers should be grouped together. The number 4 indicates that the following four numbers are a group, and the 6 indicates that the last six numbers are a group. (Hint: Use a nested loop. The outer loop should terminate when the end of file has been encountered.)

2. [20 pts] Student A B will enjoy his picnic on sunny days that have no ants. He will also enjoy his picnic any day he sees a hummingbird, as well as on days where there are ants and ladybugs. a. Write a Boolean equation for his enjoyment (E) in terms of sun (S), ants (A), hummingbirds (H), and ladybugs (L). b. Implement in Logisim, the logic circuit of E function. Use the Circuit Analysis tool in Logisim to view the expression, include an image of the expression generated by Logisim
How would I go about creating this computer database in MariaDB with sql? Create a database name "dbXXXXXX" Select the database using the "use [database name]" command. Now you are in the database. Based on the above schema from Enrolment System database, create all the tables with the last 6 digits of  "123456", then the table name for table Lecturer should be "123456_Lecturer". Refer to basic SQL lecture note to create table that has primary keys and Foreign Keys. Provide the datatype of each attributes. Add a column called "Department" with datatype "VARCHAR(12)" to the table "Lecturer". Shows the metadata of the updated "Lecturer" table. (Use Describe command) Drop the "Department" column from the table "Lecturer", and show the metadata of the updated "Lecturer" table. Insert three (3) data to each of the table in the tables created.  Note: If you have foreign key issues, please disable foreign key constraints before inserting the data, see below SET FOREIGN_KEY_CHECKS=0;…
