Write a Program: DNA Sequence Analysis



Every DNA sequence consists of four nucleotides: Adenine, Thymine, Cytosine, and Guanine,



referred to by the first letters of their chemical names (A, T, C, and G). I have provided an



entire DNA sequence in the file


dnaSequence.txt.




You goal is to provide a report of the number of each nucleotide within the sequence, and the



percent each nucleotide makes up of the total. You should include your output file in the



submission in addition to our usual submission format (console output + code).




Consider a system with 13 dedicated devices of the same type and all jobs currently running on this system require a maximum of three devices to complete their execution but they each run for long periods of time with just two devices and request the remaining one only at the very end of the run. Assume that the job stream is endless and that your operating system’s device allocation policy is a very conservative one: No job will be started unless all the required drives have been allocated to it for the entire duration of its run. a. What is the maximum number of jobs that can be in progress at once? Explain your answer.



Write a program that will display a calendar given a month and year as an input to the program. Will display only single month of year given. Here it’s that if given input as ( April 2003) will display only the given month of the year.


Using a do-while loop create a program that will prompt the user for a number and then print out a list 5 odd numbers above the given number(inclusive).

input: -25

output: -25 -23 -21 -19 -17
Design a Car model class under package :package6 with the following attributes:

Member Field Name
Type
licenceNumber
String
Model
String
currentMileage
Double
engineSize
Intege
Mark all the attributes as private & create appropriate Getters & Setters

Design another class as Main under package :package6, where you need to implement logic as follows:
Declare an array as Car with size 10.
Take 10 Carà ƒ ¢ € ™s information from user and store them in specified array.
Call findCarList method from Main class to get all cars information related to a given current Mileage & engine Size
Current Mileage & engine Size values should be taken from Main class and pass to findCarList method as argument as well as Car array (with size 10).
Design findCarList method in Car class as follows:

Create a do-while loop that ask the user to enter two numbers. The numbers should be added and sum displayed. The loop should ask whether the user he or she wishes to perform the operation again. If so the loop should repeat; otherwise it should terminate


Write a program to allow multiple sets of scores to be averaged. Valid entries must be numeric and in the range of 0 to 100. Calculate the average of the scores entered. Allow any number of scores to be entered per data set but assume that there will be at least one score entered. Use a sentinel-controlled loop variable to terminate the loop. After values are entered and average is calculated, test the average to determine whether an A, B, C, D or F should be recorded. The scoring rubric is as follows: A: 90 to 100; B80 to 89; C 70 to 79; D 60 to 69 and F <60.

Write a C++ program to find maximum marks stored in marks.txt file:

  1. Display it
  2. find average and display it.
  3. Write the average in given file.

Write a C++ program that reads the record stored in marks.txt file and display the maximum marks
