You many choose to use the hardwired data or have user to input the test data from the console.The program should ask the user to enter three test scores, which are stored in the TestScores object.The application program, lab9.cpp, should display the average of the scores, as reported by the TestScores object.Submit this lab in thee files: lab9.cpp, testScores.h, and testScores.cpp.

consider a demand-paging system with a paging disk that has an average access and transfer time of 20 milliseconds. addresses are translated through a page table in main memory, with an access time of 1 microsecond per memory access. thus, each memory reference through the page table takes two accesses. to improve this time, we have added an associative memory that reduces access time to one memory reference, if the page-table entry is in the associative memory. assume that 80 percent of the accesses are in the associative memory and that, of the remaining, 10 percent (or 2 percent of the total) cause page faults. what is the effective memory access time?

Write a program that first reads in the name of an input file and then reads the input file using the file.readlines() method. The input file contains an unsorted list of number of seasons followed by the corresponding TV show. Your program should put the contents of the input file into a dictionary where the number of seasons are the keys, and a list of TV shows are the values (since multiple shows could have the same number of seasons). Sort the dictionary by key (least to greatest) and output the results to a file named output_keys.txt, separating multiple TV shows associated with the same key with a semicolon (). Next, sort the dictionary by values (alphabetical order), and output the results to a file named output_titles.txt. Ex: If the input is: file1.txt and the contents of file1.txt are: 20 Gunsmoke 30 The Simpsons 10 Will & Grace 14 Dallas 20 Law & Order 12 Murder, She Wrote the file output_keys.txt should contain: 10: Will & Grace 12: Murder, She Wrote 14: Dallas 20: Gunsmoke; Law & Order 30: The Simpsons and the file output_titles.txt should contain: Dallas Gunsmoke Law & Order Murder, She Wrote The Simpsons Will & Grace Note: There is a newline at the end of each output file, and file1.txt is available to download.
