- in c++: Assume that you have a text file named file1.dat contains some text written into it, write a function named vowelwords(), that reads the file file1.dat and creates a new file named file2.dat, to contain only those words from the file file1.dat which start with a lowercase vowel (i.e., with 'a', 'e', 'i', 'o', 'u').Average grades bar chart Write a python program grades.py that reads a file of assignment grades and draws a bar chart of the average grades for each assignment. Save the figure as grades.png in the current working directory. The format of a line in the file is: assignment_type grade Note that there is a single space between the assignment type and the grade. E.g. exam 92.80 Your program must contain the following functions: Function name Function description Function input(s) Function return value(s) get_grades() This function takes a file name as input and populates a dictionary containing the assignment types and grades. Filename string Dictionary of grades main() This function prompts for the grades file name. Next, it calls the functions get_grades(). Next, it draws the bar chart of the average grade for each assignment. Hint: You can use the mean function of the statistics module to calculate the average of a list. None None Use the starter…1.

(write c++ code)Program: final.py Specification First, download the template file, final.py. This file contains the function names and documentation. You are required to add a header comment block with your name, the file name, the current semester, and year. Do not change the function headers, just add your implementation for each function where indicated. Add descriptive comments to your code. Remember to indent all the code for the function. Here are the functions that you will write: • Calculating tips is a common operation and the first function you write for the final project will do exactly that. The function calculate_tip accepts two parameters, the bill amount and the percent to tip, and returns the amount of the tip to write into the bill. The function should return the string "Invalid charge amount" if the charge is not more that 0 and "Invalid tip percent" if the tip is less than 0. Function heading: def calculate tip(charge, tip_percent): Parameter Specification: charge is the total ch…

- String data type is not allowed you can make use of CString instead (char arrays with null termination). Write a menu driven C++ program to perform the following four tasks in a single file, if user press option 1 the task 1 get solved and so on: 1. Display the Item_Id of the products which are not available in stock on screen. 2. Copy all the available products data in a separate file. 3. Read the original input file and update the price of each item by 10 percent increase in the original price and save the complete information in separate file. 4. Try to save the information processed in part 3 in the original file by updating it instead of using separate file.Project 8 Specifications Using OOP, write a C++ program that will read in a file of names and a file of birth years. The file of names is called Names.txt and the file of birth years is called BirthYear.txt. Both input files should be located in the current directory of your program. The list of names in the Names.txt file corresponds to the list of birth years in the BirthYears.txt file. This means:The first name in the names.txt file corresponds to the first birth year in the birthyear.txt file. The second name in the names.txt file corresponds to the second birth year in the birthyear.txt file...and so on.Read in and store the names into an array of 30. Next read in and store the birth years into another array of 30 integers.Sort the arrays using the selection sort or the bubblesort code found in your textbook. List the roster of names in ascending alphabetical order displaying their birth years beside their names.Next, prompt the user to enter a birth year. Validate this…Please use Python for this question. Please format code properly when answering the question. Write a standalone function partyVolume() that takes accepts one argument, a string containing the name of a file. The objective of the function is to determine the Volume object that is the result of many people at a party turning the Volume up and down. More specifically: the first line of the file is a number that indicates the initial value of a Volume The remaining lines consist of a single character followed by a space followed by a number. The character will be one of ‘U” or ‘D’ which stand for “up” and “down” respectively. The function will create a new Volume object and then process each line of the file by calling the appropriate method of the Volume object which changes the value of the Volume. The function then returns the final Volume object. Guidelines/hints: This is a standalone function, it should NOT be inside (indented within) the class. It should be listed in…
