Write a program that opens a specified text file then displays a list of all the unique words found in the file. Hint: Store each word as an element of a set. 5. Word Frequency Write a program that reads the contents of a text file. The program should create a dictio- nary in which the keys are the individual words found in the file and the values are the number of times each word appears. For example, if the word "the" appears 128 times, the dictionary would contain an element with 'the' as the key and 128 as the value. The

PROGRAM NEEDS TO MATCH EXAMPLE PHOTO Write a program ( lab6.cpp ) that gives and takes advice on program writing. The program starts by writing a piece of advice to the screen and asking the user to type in a different piece of advice. The program then ends. The next person to run the program receives the advice given by the person who last ran the program. The advice is kept in a file, and the contents of the file change after each run of the program. You can use your editor to enter the initial piece of advice in the file so that the first person who runs the program receives some advice. Allow the user to type in advice of any length so that it can be any number of lines long. The user is told to end his or her advice by pressing the Return key two times. Your program can then test to see that it has reached the end of the input by checking to see when it reads two consecutive occurrences of the character ‘\n’. Hints:- You need to look at each character as it is read to see if it is…
The function print_last_line in python takes one parameter, fname, the name of a text file. The function should open the file for reading, read the lines of the file until it reaches the end, print out the last line in the file, report the number of lines contained in the file, and close the file. Hint: Use a for loop to iterate over the lines and accumulate the count. For example: Test Result print_last_line("wordlist1.txt") maudlin The file has 5 lines.

Design a program that reads a file called sales.txt containing the following data: Jane, 215.5,445.5,910.0 John, 825.0,250.5,675.0 Bill,0.0,999.15 Each line has a employee's name and their weekly sales totals all separated by commas. Some employees have taken vacation some weeks so no numbers are captured for those weeks. Create a function that takes a list of floats and returns the average value for those numbers. After reading the information from the file, use a for loop to calculate the sales average using your new average function for each employee and display the following output to the screen. Jane, average sales: 523.67 John, average sales: 583.50 Bill, average sales: 499.56
Write this as Java code Exercise #3: Write a program that finds all students who score the highest and lowest average marks of the first two homework in CS (). Your program should read the data from a file called "hw2.dat" and displays the output to another file called "hw2.out" and on the screen. The first line of the input file contains the number of students, N. The next N lines contain information about the students. Each data line contains student name and his/her marks. The output should display all student names, marks, and grades. In addition, you should output the highest and lowest marks and those who earned them along with the average and the grade of the class.
