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)
Car maintenance booking provide the user the information for booking purposes. Theinformation of the booking services has several information such as slot number and status thatare stored in a file named “Services.txt”. In this case, the slot number will be used to locate theslot, while the status will be used to know the availability of the slot (i.e. ’1’ indicate the slotis occupied and ’0’ indicate the slot is available). Assuming there are 12 slot available, andhave been indexed from 1 to 12. You are required to develop a C program that can access thedata from “Services.txt”. file, and manage the slot information with the following requirements:Based on user selection, the program will perform one of the two following options:1 – Search. The program should be able to display the status, based on the slot numberentered by user.2 – Booking. A function (in 3 (a)) is called to list out all available slot (which isindicated by status ’0’). Another function (in 3 (b)) will be called to…

Data File: Example #1AAAAABBBBBCCCCCDDDDDAAEBCBAFBBCDCECDADDEFEEFFFExample #2AAATAABTBBBBCCCCTCDDTDDDAASAABBSBBCCSCCDSDDDEEEAEEFBFFFDDF Write a program that will give the user a brief introduction, then allow the user to type in the name of the file to be analyzed, the name of the data file to generate, and then process the data to match the output that is shown below. This DNA test measures the various parts of the sequence and assigns them a letter. While the letters could be anything from A to Z, the only letters that matter for this test are the letters {A,B,C,D} all other letters can be ignored completely. A sample will be tested, given a length of time and then tested again. Each time the scientist will generate a line of data. Here is one Example: Example #1 AAAAABBBBBCCCCCDDDDD AAEBCBAFBBCDCECDADDEFEEFFF At first glance the sample looks significantly different after the second test. But if you look at the data, you will note that since we only care about A,B,C,D’s that the…
Open the project or solution named mpg in this folder: ex_starts\ch07_ex1_mpg Review the code and run the program to refresh your memory on how it works. Notice that, unlike the program in this chapter, this program lets the user perform more than one calculation, it stores the values the user enters in a text file, and it displays the total miles, total gallons, and average miles per gallon when the program starts and after each entry. Add a function that calculates the miles per gallon Define a function named calculate_mpg() before the main() function that calculates the miles per gallon. This function should accept two double values for the miles and gallons, round the result to two decimal places, and return the result as a double type. Modify the code in the main() function so it uses the calculate_mpg() function. Note that the miles per gallon is calculated in three different places. Move the definition for the calculate_mpg() function after the main() function. When you run…
File redirection allows you to redirect standard input (keyboard) and instead read from a file specified at the command prompt. It requires the use of the < operator (e.g. java MyProgram < input_file.txt) True or False
True or FalseAs items are read from the file, the read position moves forward, toward the end of the file.
