- We will use the file classlist.txt. Note that it contains a list of usernames. 3. Write a script called finduser that is to be called as follows, where classlist is the name of the classlist file, and username is a particular student's username, either first name or last time. ./finduser classlist username The script should check that the correct number of arguments was received and print an error message if not, check whether the classlist file exists and print an error message if not, print the line of the given username in the classlist file If you have not been doing so all along, you should now add some comments to your script and thoroughly test it! 4. Write the script into your lab report.Verify that seven ADT list procedures, list index out of bounds exception, and list exception work.How to code this assignment JSON objects.

Recall that packages are loaded with the library function, e.g. Below these, add another line of code to read in the data from the pokemon.csv file using the read_csvfunction, and store it as a variable called pokemon. You should do this in setup chunk at the top of the Rmd file. (You can leave the columns as their default datatypes.) Make sure you use read_csv and not read.csv (read_csv is a more modern function that is part of the tidyverse).write a batch file which it can Sort based on the column in file.

If the first option is chosen, then the game should progress in the same fashion as in the tasks above. If the second option is chosen, then the following actions should be taken: Firstly, the player should be asked to enter a filename. If the player enters an invalid filename, they should be re-prompted until they enter the name of a file that actually exists. This file should then be read and interpreted as a text file, where each line contains a separate guess. For example, a sample file input.txt may contain the following text: 1234 4321 5830 8437 1489 3271 2530 You may assume that each line of the file contains a valid guess. Once the file has been read, then the game should proceed as normal. However, when the player would be prompted to enter a guess, the next guess in the list of pre-supplied…
