Part I: Write a program to compress a source file into a target file using the Huffman coding method. First, use ObjectOutputStream to output the Huffman codes into the target file, then use BitOutputStream from Assignment #2 to output the encoded binary contents to the target file. Pass the files from the command line using something like the following command: C:\Users\.... > java Compress_a_File sourceFile.txt compressedFile.txt When I did this for my source file, I got a compressed file that looked something like the following: í w Zur [Ljava.lang.String;ÒVçé{G xp ppppppppppt 01101ppt 11010ppppppppppppppppppt 100pppppppppppt 10101pt 1111010ppppppppppppppppppt 011000pppppppppPPPPPPpt 1010011pt 1111011pt 1101110ppppppppppt 110110t 1101111t 00000t 01111 010t 101000pt 00001t 11111ppt 01110t 00010t 00011t 1110t 111100pt 1011t 001t 1100t 011001pppt 1010010pppppppppppppppPPPPPPPPpppppppppppppppppppppppPPPPPPPPppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppw 0§Ãµiów MieWM÷ttËDÏÌ£ïUÓXæ-...gògw Part II: Write a second program, Decompress_a_File.java, to decompress a previously compressed file so that it replicates the original source file in Part I above. You would do this at the command line with a command that looks like the following: C:\Users\...> java Decompress_a_File compressedFile.txt decompressedFile.txt When I ran this second program on my compressed file from Part I above I got: Roses are red, Violets are blue, Try to compress this file, And then decompress it too.

Each of the following files in the Chapter.02 folder of your downloadable student files has syntax and/or logical errors. In each case, determine the problem and fix the program. After you correct the errors, save each file using the same filename preceded with Fixed. For example, DebugTw01.cs will become FixedDebugTw01.cs. a. DebugTw01.cs b. DebugTw02.cs c. DebugTw03.cs d. DebugTw04.cs

1. Consider the following incomplete C++ program: #include int main() { … } a. Write a statement that includes the header files fstream, string, and iomanip in this program. b. Write statements that declare inFile to be an ifstream variable and outFile to be an ofstream variable. c. The program will read data from the file inData.txt and write output to the file outData.txt. Write statements to open both of these files, associate inFile with inData.txt, and associate outFile with outData.txt. d. Suppose that the file inData.txt contains the following data: Giselle Robinson Accounting 5600 5 30 450 9 75 1.5 The first line contains a person's first name, last name, and the department the person works in. In the second line, the first number represents the monthly gross salary, the bonus (as a percent), and the taxes (as a percent). The third line contains the distance traveled and the traveling time. The fourth line contains the number of coffee cups sold and the cost of each coffee cup. Write statements so that after the program executes, the contents of the file outData.txt are as shown below. If necessary, declare additional variables. Your statements should be general enough so that if the content of the input file changes and the program is run again (without editing and recompiling), it outputs the appropriate results. Name: Giselle Robinson, Department: Accounting Monthly Gross Salary: $5600.00, Monthly Bonus: 5.00, Taxes: 30.000 Paycheck: $4116.00 Distance Traveled 450.00 miles, Traveling Time: 9.00 hours Average Speed: 50.00 miles per hour Number of coffee Cups Sold: 75, Cost: $1.50 per cup Sales Amount = $112.50 e. Write statements that close the input and output files. f. Write a C++ program that tests the statements in parts a through e.
