What does the following code do? FileInputStream fis = new FileInputStream("test.dat"); It creates a new file named test.dat if it does not exist and opens the file so you can write to it. It creates a new file named test.dat if it does not exist and opens the file so you can write to it and read from it. It creates a new file named test.dat regardless of whether it exists or not and opens the file so you can write to it. It creates a new file named test.dat regardless of whether it exists or not and opens the file so you can write to it and read from it. It creates a FileInputStream for test.dat if test.dat exists.

Please in C Language Write a program that uses an existing text file (text.txt) to determine the number of occurrences of each letter. You can assume that the file is filled with only lowercase letters and only the letters from a-z are present! Write the result in a new file to be created by the program! Errors when opening and closing the files must be caught Data.txt I love my money
Instructions The history teacher at your school needs help in grading a True/False test. The students’ IDs and test answers are stored in a file. The first entry in the file contains answers to the test in the form:TFFTFFTTTTFFTFTFTFTTEvery other entry in the file is the student ID, followed by a blank, followed by the student’s responses. For example, the entry:ABC54301 TFTFTFTT TFTFTFFTTFTindicates that the student ID is ABC54301 and the answer to question 1 is True, the answer to question 2 is False, and so on. This student did not answer question 9. The exam has 20 questions, and the class has more than 150 students. Each correct answer is awarded two points, each wrong answer gets one point deducted, and no answer gets zero points. Write a program that processes the test data. The output should be the student’s ID, followed by the answers, followed by the test score, followed by the test grade. Assume the following grade scale:90%–100%, A; 80%–89.99%, B; 70%–79.99%, C; 60%–69.99%,…
1. Write a program that opens an output file with the filename my_name.txt, writes your name to the file, then closes the file. 2. Write a program that opens the my_name.txt file that was created by the program in problem 1, reads your name from the file, displays the name on the screen, then closes the file. Write code that does the following: opens an output file with the filename number_list.
File encryption is the science of writing the contents of a file in a secret code. Your encryption program should work like a filter, reading the contents of one file, modifying the data into a code, and then writing the coded contents out to a second file. The second file will bea version of the first file, but written in a secret code.Although there are complex encryption techniques, you should come up with a simple one of your own. For example, you could read the first file one character at a time, and add 10 to the character code of each character before it is written to the second file. Write a program that decrypts the file produced by the program in above.The decryption program should read the contents of the coded file, restore the data to its original state, and write it to another file.
Write a code segment that creates an ofstream object named outfile, opens a ﬁle named numbers.txt, and associates it with outfile. The code should then use a loop to write the numbers 1 through 100 to the ﬁle before closing it.

Prog 1. File Encryption: File encryption is the science of writing the contents of a file in a secret code. Your encryption program should work like a filter reading the contents of one file, modifying each character in the input file into a code, and then writing the coded characters out to a second file. The second file will be a version of the first file but written in a secret code. In Notepad or something similar, you will create a file with text in it. It should be several lines long. Your program should read the file character by character and make some change to the character before writing that character to a second new encrypted file. See program 13-8 to see how to read and write one character at a time. You may come up with an encryption technique of your own or use something simple like adding 10 to the ASCII code of each character in the file before it is written to the second file.
Write a code segment that creates an ifstream object named infile, opens the numbers.txt ﬁle created by the code in the previous question, and associates it with infile. The code should then use a loop to read and display all of the numbers in the ﬁle before closing it.
Create a program named FileComparison that compares two files. First, use a text editor such as Notepad to save your favorite movie quote. Next, copy the file contents, and paste them into a word-processing program such as Word. Then, write the file-comparison application that displays the sizes of the two files as well as the ratio of their sizes to each other. To discover a files size, you can create a System. 10. Filelnfo object using statements such as the following, where FILE_NAME is a string that contains the name of the file, and size has been declared as an integer: FileInfo fileInfo = new FileInfo(FILE_NAME); size = fileInfo.Length;
CODE IN PYTHON PLEASE The objective is to create a code in Python that can extract the columns highlighted in blue (Column T and AB3) and output them to a .txt file. The code should be able to generate the text file with the columns that are highlighted in blue and store them on a separate folder. Below shows how the Test.xlsm file looks like as well as how the text file should look like when the code extracts and outputs it. Google drive to access Test.xlsm file: https://drive.google.com/drive/folders/16utzb5_h7yMCN8_13E_JqasfcpykZOYr?usp=sharing What my code outputs is shown in the picture (O1.png) What I would like for my code to output is the columns next to each other (Right Example.png) The current code is able to output Columns T and AB3 but I am not able to output them next to each other as shown above. We would also like for the code to be capable of storing the text file to a separate folder. Below is the code I have been working on. #package to read xlsm file import openpyxl…

The Springfork Amateur Golf Club has a tournament every weekend. The club president hasasked you to write two programs:1. A program that will read each player’s name and golf score as keyboard input, then savethese as records in a file named golf.txt. (Each record will have a field for the player’sname and a field for the player’s score.)2. A program that reads the records from the golf.txt file and displays them.
