Question
Write a
For example, this would be an acceptable file:
Your program should open this file and:
- print all its contents;
- write the median of all numbers to a new file called result.txt.
IMPORTANT NOTES:
- the median is the element in the middle when you sort the values;
- the median of values (2, 1, 3) is 2, because when you sort them, you get 1, 2, 3, and 2 is the value in the middle.
- you can assume there will be no empty lines;
- there might be any arbitrary number lines in the file;
- there might be any arbitrary number of elements in a single line;
- you can assume there will always be an odd number of elements.
Example 1:
If input is:
file1.txtand the contents of file1.txt are:
1 2 2you should first print the content, and then write 2 to result.txt.
Example 2:
If input is:
file2.txtand the contents of file2.txt are:
1 2 3 4 5 1 7you should first print the content, and then write 3 to result.txt.
The elements sorted are: 1, 1, 2, 3, 4, 5, 7. In this sequence, 3 is the middle value, so it is the median.

- In this project, you will develop algorithms that find road routes through the bridges to travel between islands. The input is a text file containing data about the given map. Each file begins with the number of rows and columns in the map considered as maximum latitudes and maximum longitudes respectively on the map. The character "X" in the file represents the water that means if a cell contains "X" then the traveler is not allowed to occupy that cell as this car is not drivable on water. The character "0" in the file represents the road connected island. That means if a cell contains "0" then the traveler is allowed to occupy that cell as this car can drive on roads. The traveler starts at the island located at latitude = 0 and longitude = 0 (i.e., (0,0)) in the upper left corner, and the goal is to drive to the island located at (MaxLattitude-1, MaxLongitudes-1) in the lower right corner. A legal move from an island is to move left, right, up, or down to an immediately adjacent…arrow_forwardWord Puzzle GameIn this assignment is only for individual. You are going to decode the scrambled word into correct orderin this game. One round of play is as follows:1. Computer reads a text file named words.txt2. Computer randomly picks one word in the file and randomly scrambles characters in the wordmany times to hide the word3. Computer displays the scrambled word to user with indexes and gives the user options to1. Swap two letters in word based on index given2. Solve the puzzle directly3. Quit the game4. If a player chooses to swap letters, the computer reads two indexes and swaps the letters. Thegame resume to step 3 with the newly guessed word. If the resulted word after swapping is thesecret word, the game is over.5. If a user chooses to solve directly, computer prompts the user to enter the guessed word. If it’scorrect, the game is over, otherwise goes to step 3.6. After game is over, display how many times the player has tried to solve the puzzle.The following is sample…arrow_forwardGiven a text file containing the availability of food items, write a program that reads the information from the text file and outputs the available food items. The program first reads the name of the text file from the user. The program then reads the text file, stores the information into four separate arrays, and outputs the available food items in the following format: name (category) -- description Assume the text file contains the category, name, description, and availability of at least one food item, separated by a tab character. Ex: If the input of the program is: food.txt and the contents of food.txt are: Sandwiches Ham sandwich Classic ham sandwich Available Sandwiches Chicken salad sandwich Chicken salad sandwich Not available Sandwiches Cheeseburger Classic cheeseburger Not available Salads Caesar salad Chunks of romaine heart lettuce dressed with lemon juice Available Salads Asian salad Mixed greens with ginger dressing, sprinkled with sesame Not available Drinks Water…arrow_forward
- In C++ Query the user for the name of a file. Open and process that file, reporting the number of words in the file and the number of words containing each letter, and the length of that word. Assume that any word exceeding nine characters is counted as a ten character word. If the same letter appears more than once, it is counted only once. The result should be a matrix of 26 rows (one row for each letter) and ten columns (one column for each word length (1-10), and the contents of the matrix must be displayed. As an example, assume the file contains only two words - “rotten” and “egg”. When processing “rotten”, rows for r, o, t, e and n would have the contents of column 6 incremented because “rotten” is a six letter word. When processing “egg”, rows for e and g would have the contents of column 3 incremented because “egg” is a three letter word.arrow_forwardC++ Write a program that reads the student information from a tab separated values (tsv) file. The program then creates a text file that records the course grades of the students. Each row of the tsv file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student. A sample of the student information is provided in StudentInfo.tsv. Assume the number of students is at least 1 and at most 20. Assume also the last names and first names do not contain whitespaces. The program performs the following tasks: Read the file name of the tsv file from the user. Open the tsv file and read the student information. Compute the average exam score of each student. Assign a letter grade to each student based on the average exam score in the following scale: A: 90 =< x B: 80 =< x < 90 C: 70 =< x < 80 D: 60 =< x < 70 F: x < 60 Compute the average of each exam. Output the last names, first names, exam scores, and letter grades of the…arrow_forwardWrite a program that reads movie data from a csv (comma separated values) file and output the data in a formatted table. The program first reads the name of the CSV file from the user.

A space is placed before and after each vertical separator (|) in each row. Column 1 displays the movie titles and is left justified with a minimum of 44 characters. If the movie title has more than 44 characters, output the first 44 characters only. Column 2 displays the movie ratings and is right justified with a minimum of 5 characters.
