Im looking for question 5. I havvve attatched the sortedlist.h and sortedlist.cpp

SOTEDLIST.CPP

SORTEDLIST.H

Many instructors like to see the distribution effective prompts, and program working for an art of scores on an exam before they assign are at that will all of the scores from an exam and print out a bar chart that most distribution. The range of professor who has asked you to develop a chapter as 250 students the scores varies from exam to exam, necessary to in the class. Use modify the from this help you do this task. The integer scores are entered into a file called exams dat in random order. Your program\'s job is to read in the data, sort it, first bar in a bar chart (star) for each exam that has a particular score. The the chart should be the highest score, and the last bar in the chart should be the lowest score. Each line of output should start with the score value, followed by the appropriate number of stars. When there is a score value that didn\'t appear on any exams, output the value and no stars, then go to the next line. 4 Enhance the program in Problem 3 as follows: The data file now contains a score and a name. Modify the sortedList class so that it uses a struct consisting of the score and the name as its fields. The program should input the file data into the modified list. In addition to displaying the bar chart, the program should output the sorted list to a file called by score dat. 5. You\'ve gathered lists of email addresses from a variety of sources, and now you want to send out a mass mailing to all of the addresses However, you don\'t want to send out duplicate messages. All of the email addresses as combined on a single file called rawl You need to write a program that reads all of the addresses and discards any that have been previously input. of the list classes from this chapter, modifying it as necessary to work with string data, and to deal with as many as 1000 items. After all of the data have been read, output the new mailing list to a file called clean list. dat.
