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…

Write a code segment that creates an ofstream object named outfile, opens a file named numfile.txt, and associates it with outfile. Then write the contents of the variable data to the file, followed by a newline, then close the file.
in C# Code in VS studio:
Create a program that has 2 options for a user to select.
The first option accepts information from the user and then save that data to a file on disk.
The second option loads all data stored on that file.

The total of the 3 quizzes constitutes 50% of the course grade. Final exam: The final exams is graded on a scale from 0 to 100. The final exam constitutes 50% of the course grade. Write a computer program in a script file that determines the course grade for a student. The program first asks the user to enter the 3 midterms grades (In a vector) and the grade of the final. Then the program calculates a numerical course grade (a number between O and 100). The course grade is rounded to one decimal points. Sample Output: Please enter Midterm 1 grade : 30 Input should be between 0 and 20, Please enter Midterm 1 grade : 20 Please enter Midterm 2 grade : 15 Please enter Midterm 3 grade : 17.8 Please enter final exam grade: 80 The course grade is 66.4 Click Below Matlab Link: https://matlab.mathworks.com For…arrow_forwardWrite a code segment that creates an ifstream object named infile, opens the numbers.txt file created by the code in the previous question, and associates it with infile.

- IN JAVA Arrange the data for your chart in a text file as follows: The first line of the file is the title for the chart The second line of the file is the units used in the chart The rest of the file contains data values for the chart alternating with the label to print with the value on the preceding line. The program must be able to produce a chart from any data file arranged as described above. The name of the data file and the output file are provided on the command line. The program must check that there are enough command line arguments and stop with a suitable message if not. The program saves the chart to the output file (2nd command line argument); it may also display the chart to the terminal, but it is not required to. In addition to the above, accept two additional command line arguments: The maximum width for the chart (just the bar itself, not including the labels) The symbol to use for the barsarrow_forward#function read file and display reportdef displayAverage(fileName):#open the fileinfile = open(fileName, "r")#variable declaration and initializationtotal = 0count = 0#read filefor num in infile:total = total + float(num)count = count + 1#close the fileinfile.close()#calculate averageaverage = total / count#display the resultprint("Average {:.1f}".format(average)) #method callingdisplayAverage("numbers.txt")arrow_forwardC++ Assignment Setup Part 1: Working With Process IDs Modify the getProcessID() function in the file named Processes.cpp The function must find and store the process's own process id The function must return the process id to the calling program.

- Write a statement that defines a file stream object named people. The object will be used for file output.arrow_forwardanswer in python Design and write a program that calculates and displays the number of minutes over the monthly contract minutes that a cell phone user incurred. The program should allow users to enter into a file minutes allowed in a month, minute used during a month and minutes over during a month for 12 months. The program reads the data from the file. The program validates the data as follows: - The minimum minutes allowed should be at least 200, but not greater than 800. Validate data accordingly. - The minutes used must be over 0. Validate data accordingly. Once correct data is read, the program should calculate the number of minutes over the minute allowed. If minutes were not over, print a message that they were not over the limit. If minutes were over, for every minute over, a .20 fee should be added to the monthly contract rate of 74.99. Be sure not to add the .20 fee for minutes 1 to the number of minutes allowed, but rather just minutes over.
