Problem description Write a program that will read in a file of student academic credit data and create a list of students on academic warning. The list of students on warning will be written to a file. Each line of the input file will contain the student name (a single String with no spaces), the number of semester hours earned (an integer), the total quality points earned (a double). The program should compute the GPA (grade point or quality point average) for each student (the total quality points divided by the number of semester hours) then write the student information to the output file if that student should be put on academic warning. A student will be on warning if he/she has a GPA less than 1.5 for students with fewer than 30 semester hours credit, 1.75 for students with fewer than 60 semester hours credit, and 2.0 for all other students. Do the following:

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…
Python - Next Birthdate In this task, we will write a program that reads birthdate data from a given CSV file, and given the current date, determines which person's birthday will be celebrated next. Create a function with the following signature: nextBirthdate(filename, date) filename: parameter, which represents the CSV filename. date: parameter, which represents the current date. The function should open the CSV file, read the birthdate data, and determine which person's birthday will be celebrated next, given the current date. The name of the person should be returned. In other words, given a date, find the person whose birthday is next. Sample Run birthdates.csv Draven Brock, 01/21/1952 Easton Mclean, 09/02/1954 Destiny Pacheco, 10/10/1958 Ariella Wood, 12/20/1961 Keely Sanders, 08/03/1985 Bryan Sloan,04/06/1986 Shannon Brewer, 05/11/1986 Julianne Farrell,01/29/2000 Makhi Weeks, 03/20/2000 Lucian Fields, 08/02/2018 Function Call nextBirthdate("birthdates.csv", "01/01/2022") Output…
C++ formatting please Write a program (not a function) that reads from a file named "data.csv". This file consists of a list of countries and gold medals they have won in various Olympic events. Write to standard out, the top 5 countries with the most gold medals. You can assume there will be no ties. Expected Output: 1: United States with 1022 gold medals 2: Soviet Union with 440 gold medals 3: Germany with 275 gold medals 4: Great Britain with 263 gold medals 5: China with 227 gold medals
Body Mass Index Write a program that reads names, weights, and heights from bmi.dat (provided with starter code; do not change the file name). Use the information to calculate and displays a person’s body mass index (BMI). The BMI is often used to determine whether a person with a sedentary lifestyle is overweight or underweight for his or her height. A person’s BMI is calculated with the following formula: BMI = weight × 703 / height2 where weight is measured in pounds and height is measured in inches. The file is in the format name weightInKG heightInCM You will read the name, weight and height for 4 people from the file, and you will need to convert the weights in the file to pounds (note that 1 kilogram = 2.2 pounds) and the heights to inches (2.54 cm = 1 inch). The program should display the person's name along with the calculated BMI and a message indicating whether the person has optimal weight, is underweight, or is overweight. Your output should look like A person’s weight…
C++ Write a program that reads the student information from a tab separated values (tsv) file. The program then creates a text file that records the course grades of the students. Each row of the tsv file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student. A sample of the student information is provided in StudentInfo.tsv. Assume the number of students is at least 1 and at most 20. Assume also the last names and first names do not contain whitespaces. The program performs the following tasks: Read the file name of the tsv file from the user. Open the tsv file and read the student information. Compute the average exam score of each student. Assign a letter grade to each student based on the average exam score in the following scale: A: 90 =< x B: 80 =< x < 90 C: 70 =< x < 80 D: 60 =< x < 70 F: x < 60 Compute the average of each exam. Output the last names, first names, exam scores, and letter grades of the…

In C++ code: Design and write a C++ class that reads text, binary and csv files. The class functions: Size: Returns the file sizeName: Returns the file nameRaw: Returns the unparsed raw dataParse: A external function to Parse the data. The function accepts the raw data and returns the data parsed by the function. This type of function is called a "Call-Back Function". A Call-Back is necessary for each file as each file requires different regular expressions to parse. Call-back.cpp #include <string>#include <functional>#include <iostream>#include <vector>using namespace std; string ToLower(string s){ string temp; for (char c : s) temp.push_back(tolower(c)); temp.push_back(NULL); return temp;} string ToUpper(string s){ string temp; for (char c : s) temp.push_back(toupper(c)); temp.push_back(NULL); return temp;} struct Append{ string operator()(string a, string b) // function object { return a…
