- Write a program that writes user input to a text file and then reads the contents from that file. You will need to perform the following steps. Prompt the user for the name of a file to append to and then another prompt for them to enter a sentence. Open the file they requested in append mode and write the user_sentence to this file. Don't forget to close the file when you are done writing to it (explicitly or implicitly). Open the file you just wrote to in read mode and read the contents of the file. Print the complete file contents to the console/shell. Provide comments in your code to explain the logic used. Ensure your program works as expected by testing it with different sentences.arrow_forwardInstructions 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%,…arrow_forwardInstructions The history teacher at your school needs help in grading a True/False test.

- Last lab, we modified the inventory program to write a file. This lab, we’ll modify it to read a file. First, take your program from the last lab. Add one more feature: at the end, just before you close the file, write the word “END” all by itself on a line. Run that program once to create a file of items with “END”. Now, copy that program to a new file cp lab7.cpp lab8.cpp so you can use it as a basis for this lab. Modify lab8 so instead of reading from cin and writing to a file, you read from your file and write to cout. The only tricky part is deciding when to stop reading. In lab7, you stopped reading when the user said they didn’t want to continue. For lab8, keep reading until you read “END” for the name of the produce. You can use “==” on strings, so if (product name == ”END”) will tell you that you can stop reading.

The user of the program has four options: Add a new person, delete a person, modify the data of a person, and search for a person by giving the name. Use the AddressBook class, either the original one from the chapter or the modified one from the previous exercises. You have to decide how to allow the user to enter the values for a new person, display person information, and so forth.arrow_forwardWrite a program that allows the user to navigate the lines of text in a file. The program should prompt the user for a filename and input the lines of text into a list. The program then enters a loop in which it prints the number of lines in the files and prompts the user for a line number. Actual line numbers range from 1 to the number of lines in the file. If the input is 0, the program quits. Otherwise, the program prints the line associated with that number.arrow_forward

The program then enters a loop in which it prints the number of lines in the file and prompts the user for a line number. Actual line numbers range from 1 to the number of lines in the file. If the input is 0, the program quits. Otherwise, the program prints the line associated with that number. An example file and the program input and output is shown below: example.txt Line 1.Line 2.Line 3. Enter the input file name: example.txt The file has 3 lines. Enter a line number [0 to quit]: 2 2 : Line 2. The file has 3 lines. Enter a line number [0 to quit]: 4 ERROR: line number must be less than 3. The file has 3 lines. Enter a line number [0 to quit]: 0 Make sure the program gracefully handles a user entering a line number that is too high.arrow_forwardWrite a program that allows the user to navigate the lines of text in a file.

- Write a program (in Java or C++), allowing to: • Create a folder "Main" • Create a file in the folder "File1" Add Read, Write permissions to "File1" Write in "File1" ● ● Read the content of "File1" ● Modify the content of "File1" Remove the Write permission of "File1" Try to write again in "File1" ● A screenshot is needed showing the results of the program execution.arrow_forwardC++ A teacher is requiring her students to line up in alphabetical order, according to their first names..For example, in one class Chapel, Christine would be at the front and Uhura, Nyota would be last. The program will get the names from a file using getline since the file name includes spaces. The names should be read in until there is no more data to read. The program should prompt the user for the file name and read the data from the file. Note that these names might include spaces; handle your input accordingly. The expected output is two names; do not show the entire file. Do not use arrays or sorting for this problem.arrow_forwardPlease do this in Python: Write a program that allows the user to navigate lines of text in a file. The program should prompt the user for a filename, read the file and input the lines of text into a list. The program then enters a loop in which it prints the number of lines in the file and prompts the user for a line number. Actual line number range from 1 to the number of lines in the file. If the input is 0, the program quits. Otherwise, the program prints the text associated with that number.arrow_forward
