The final exams are graded. Due to time constraints, I counted the best three of four programs towards your final score. Also, there was one question on the sorts and searches page that I tossed since everyone missed it.
Comp 137 officially ended with the end of last night's exam. In the best interest of certain students, I am willing to accept lab submissions up until 6pm tomorrow (Wednesday) evening.
This assignment requires that you generate 100 pseudo-random numbers, between 0 and 9, inclusive. You need to use an array to keep track of how many times each digit is generated. The most efficient way to do this is to create one ten-integer array, named counts, and to increment the contents of the appropriate array location each time its value is randomly generated. That is, each time your code generates a 0, you increment the contents of counts[0]; each time your code generates a 1, you increment the contents of counts[1]; and so on.
Write a program that reads in an unknown number of integer values from a text file and stores them in a vector. Display the unsorted values then sort and sum the values. Display the sorted values, the average value, and total count to the user. Make sure to use an iterator to process the vector.
Register for the spring term before the end of the fall semester! You will have a better selection of classes and sections if you do. Also, you should be aware that if you wait too long, there is the possibility that a section you want could be cancelled due to insufficient enrollment.
Read chapter 10, Applications of Arrays (Searching and Sorting) and the vector Type.
I strongly suggest that each student develop a C++ solution to the following problems in preparation for the coding portion of the first exam. While I do not promise that the practical part of the exam will be *exactly* the same as any one of these problems, the actual test question will at least be very similar to one or more of these practice problems.
Your final exam is scheduled in class for December 19th. Keep an eye on the blog for test preparation suggestions. Programming problems on exams are often very similar to the end of chapter exercises.
As one of the requirements to earn an A- or higher, you must complete exercise 9 on pp 541-542 regarding temperature highs, lows, and averages. Please note that I have changed the requirements from the exercise in the book slightly: you are to track a single week's data, not an entire year's.
You are to complete exercise 7, p540, writing a program which contains four user-defined functions. One function reads in the data from the user; one sums the votes received by all candidates; one calculates the percentage of the total received by each individual candidate; and one displays a table of the final results.
Read chapter 9, Arrays and Strings.
You are to complete Lab 8, the programming assignment on page 11 of the course syllabus. You will need to use several of the functions of the string class in order to complete this assignment. I am inserting notes for the functions required in the bullet list of requirements below.
Read chapter 9, Arrays and Strings, pages 496-502.
Read chapter 8, User-Defined Simple Data Types, Namespaces, and the string Type.
As of dinner time last night, connectivity was restored to campus. The IT staff continues to monitor the situation any signs of instability or trouble and Brookdale email seems to be working just fine now.
For those who came to class and took the second exam, the tests are graded and five students earned full credit.
I strongly suggest that each student develop a C++ solution to the this second set of practice problems in preparation for the coding portion of the second exam. While I do not promise that the practical part of the exam will be *exactly* the same as any one of these problems, the actual test question will at least be very similar to one or more of these practice problems.

Your second exam, on chapters 5 through 7 of the textbook, is scheduled for next Tuesday, November 22nd. Keep an eye on the blog this week for test preparation suggestions. Programming problems on exams are often very similar to the end of chapter exercises.
As one of the requirements to earn a B- or higher, you must complete exercise 5 on p 409, a program to calculate which day of the year the user entered. At the very minimum, you will need to write two functions. These are their headers:
You are to complete exercise 9, pp 409-410, writing a program which contains three user-defined functions: generateOutputFile, calculateAverage, and calculateGrade. Please note that I have changed the requirements from the exercise in the book slightly, in order to have a more intuitive solution. These are the headers:
Read chapter 7, User-Defined Functions II.
Priority registration is underway! In order to give yourself the best chance of getting all of the classes you need as well as the days and class meeting times you prefer, you should register early.
As one of the requirements to earn a B- or higher, you must complete exercise 6 on pp 341-342, which requires you to solve a set of problems regarding the calculation of properties of a circle.
You are to complete exercise 2, p 340, writing a program which contains a user-defined function, isVowel. This is its header:
You are to complete exercise 5, p 341, writing a program which contains a user-defined function, reverseDigit. This is its header:
I have finished grading the first exam. Several students did very well prior to the application of the curve. Several students did not. The five no-shows (Fs in the table) must see me in order to make arrangements for make up exams.
These are solutions to the programming problems from this week's exam. Please note that the methods presented are not the only way to solve the problems assigned. If you used a different approach and your code generated a valid answer, you could still earn full credit.
I am still in the process of grading the exams from Monday night. In the meanwhile, you might like to review the following solutions to the short answer section of the exam. I am planning to also post some source code solutions to the programming problems presented on the test.
Read chapter 6, User-Defined Functions I.
I was reviewing today's batch of source code submissions and I noticed that an awful lot of people were not making good use of their whitespace. Please observe the following rules in your code:
I strongly suggest that each student develop a C++ solution to the following problems in preparation for the coding portion of the first exam. While I do not promise that the practical part of the exam will be *exactly* the same as any one of these problems, the actual test question will at least be very similar to one or more of these practice problems.
I reviewed Monday's pretest answers today. Looking at only the first page, the seven multiple choice questions, the class average was 51.6%. Three students tied for the highest score of 71.4%. All other scores were below 60%
These are the solutions to the last two programming problems at the end of Monday night's pretest.
Quite a few students seemed to have difficulty with the questions requiring code to be written, whether on paper or in the computer. Instead of responding to each student individually, I am providing the source code solutions to the last four problems on the pretest. Questions 8 and 9 are solved here and questions 10 and 11 are in the next post.
Your first exam, on chapters 1 through 5 of the textbook, is scheduled on Monday. Keep an eye on the blog this week for test preparation suggestions. Programming problems on exams are often very similar to the end of chapter exercises.
Today is the end of the third WebAdvisor monitoring interval. Students with attendance issues, poor homework performance, and/or missing assignments should take this warning seriously.
You are to write a program that calculates a random number from 1 to 10. Ask the user to guess the number. If the user guesses correctly, display a congratulatory message. If the user displays an incorrect answer, give the user two more tries. If after three attempts the user still has not guessed the number, display a message to that effect and terminate the program.
Notice to all students:
If you would like to write an enhanced version of the second homework assignment, you can read in a char (instead of an int) and you can switch on the character entered. If you apply the tolower() function to that input character, you can make your program transparently deal with case sensitivity:
Notice to all students:
The first annual Brookdale Community College 5K run/walk to raise money for scholarships for the International Center Study Abroad Program is scheduled for Sunday, October 30th at 9:00 at Thompson Park. The cost is $25, and if you register before the 14th it includes a commemorative T-shirt. All of the donations go to the program.
The results for this first quiz were fairly well mixed. Some students had a firm grip on the logical operators and produced complete and correct output. Some students had mostly correct output with one or two errors. Some students were able to correctly use cout to send text to the console but couldn't remember the truth tables. All in all, not unexpected results for a first quiz.
You are to complete exercise 2, p 300.
You are to complete exercise 7, p 226.
You are to finish completing exercise 20, p 27 by creating a working console application which implements the algorithm which you developed as the solution to the problem for Lab 1.
