Post the source code (embed the code in your response; DO NOT ATTACH THE C++ FILE).
Use python language for a program that modifies and sorts the content of a specific csv file based on the inputted column name. The program should ask Enter filename: Enter column name to be sorted: Additionally, the csv file must be modified and no additional csv files must be created. The application will catch and display an error message "the file does not exist" if the csv file does not exist. *if possibe, do not use pandas*

- 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.

Each line contains the following, separated by semicolons: • The name of the client, the service sold (such as Dinner, Conference, Lodging, and so on), • The amount of the sale, and the date of that event. • Write a program that reads such a file and displays the total amount for each service category. Display an error if the file does not exit or the format of the record is incorrect. No need to display anything else in this regard. Note that you can assume that the dates are entered correctly (no need to validate them). You may also assume that the name of the input text file is inputex4.txt. • Make sure you use a dictionary in your solution. • Sample run is included below for the given input file inputex4.txt Summary of total sales according to services Dinner 634.75 Conference 1133.25 Lodging Dinner and Lodging 550.25 625.14 Slide Tyne Fragment varrow_forward

- write the code to lookup, add and remove phoneentries from the phonebook text file . These are the code we use for the lookup, add and remove in the case statement.(Lookup)# Look someone up in the phone bookgrep $1 phonebook (add)echo "$1 $2" >> phonebooksort -o phonebook phonebook (Remove)grep -v "$1" phonebook > /tmp/phonebookmv /tmp/phonebook phonebook Write a complete Bash script which will accept up to three command-line arguments: the first one is either (lookup, add or remove), the second one is a name enclosed in single quotes and the third one (if doing an add) is a phone number enclosed in single quotes. Using a case statement to match on either lookup, add or remove, the script should then perform the requested operation. Again here, you should first check for null arguments before continuing with the rest of the script or requested operation. In addition, the person may not be in the phonebook for lookup or remove so, you need to account for this.arrow_forwardCreate a new text file using a notepad or any other software, The text file contains your name(first 8 chars) and the file must be exactly 8 bytes in size only and name it “your_ID.txt”.arrow_forwardUsing C++ Language Create a file called input9B.txt and type (or copy) the following text exactly as it appears below into that file.

C++ was developed by Bjarne Stroustrup, as an extension to the C language. C++ gives programmers a high level of control over system resources and memory. C++ is one of the world's most popular programming languages. C++ can be found in today's operating systems, Graphical User Interfaces, and embedded systems. C++ is an object-oriented programming language which gives a clear structure to programs and allows code to be reused, lowering development costs. Compile and run the program, using the input9B.txt file as the input file. Did this program produce the same exact output as shown above? What do you think the problem is?
