C Sharp Random Number File writer Create an application that writes a series of random numbers to a file. Each random number should be in the range of 1 through 100. The application should let the user specify how many randome numbers the file will hold and should use a SaveFileDialog control to let the user specify the file's name and Location.

Menu option B -- Determine GradeThe program will READ in data from a text file named Grades.txt. The user corrects any bad data. The program updates the information in Grades.txt file. For example, if the file contains 55 credits which exceeds the max credits you can take during one semester. You will create and submit a text file with a minimum of 5 records in addition to the example below. The file is named Grades.txt and contains the following format: first line full namesecond line number of creditsthird line study hours Such asPatrick Mahomes1236DesHAun waTson9appledrew BrEeS5515JULIO JONES1545 The program determines the grade, assuming it’s the same grade for each classAll data must be displayed in proper case such as Wendy Payne, i.e. no names should be in all lower case or all upper case or a mix such as wendy or PaYNe. Use module(s) to convert to proper case.The program displays the student’s name, number of credits, total weekly study hours, and desired gradeThe information…

BAGGINS Trucking maintains a trip file in which each record contains the following data:DRIVER nameMILES driven on tripHOURS driven on trip Design an application that inputs records from the file (until reaching "eof") and, for each record, displays the DRIVER's name and the average Miles-per-Hours (MPH) for the trip where MPH is calculated by dividing the MILES by the HOURS. The program should also accumulate a GRAND total of the MILES driven. At the end, the program should display the GRAND total of the MILES driven. For example, if the trip file contained the following:Smith, 300, 5Williams, 750, 10Jones, 880, 11 then the program should display:Smith averaged 60 mphWilliams averaged 75 mphJones averaged 80 mphGrand total of miles is 1,930 Pseudocode:

Consider the following method: public a(String s) {int v = 0;for(int x = 1; x < s.length; x=x+1) {if(s[x] == 'a' || s[x]=='e' || s[x] == 'i' || s[x] == 'o' || s[x] == 'u') { v = v + 1; }}return v;} Exactly how many lines of code (statements) are executed by the method a() in the worst case?    Express your answer in terms of n, the length of the string s. Hint:  simplify your final answer as much as possible, and do not put spaces in your answer.  Use juxtaposition for the multiplication operator, for example to write "nine times n" write "9n" not "9xn" or "9*n";  to write "four times (n+2)" write "4(n+2)", not "4x(n+2)" or "4*(n+2)".  Do not write your answer in Big-O notation.  Write the exact number of lines executed.

python function that creates and saves data in a file. the saved data represents exam grades. in the function , you will create n random numbers in the range 1-100, where n is the number of students. The function can be called as follows: createFile(filename, n)    main function, in which the user inputs the file name and the number of students, then the main calls function createfile. the main should preform validation for n (should be > 0), and the filename(should end with .txt)

Files Class Activity Write a program to write your first name (hard coded) to the screen and possibly to a file whose name is passed into the program from the command line. It can be written in upper or lower case or mixed case as the default. Usage: writer [-f filename] If the -f option is included with a filename, then create a file with that name or overwrite a previously existing file and write your name in on the first line. If the -f option is not included, then only write your name to the screen followed by a newline. Use a copy of the original getopt to parse the command line. Be sure to test whether a file open succeeds or not and close any file you open when done.
