Letter Frequencies
The letter e is the most frequently used letter in English prose, and the letter z is the least frequently used. A friend of yours doing a sociology experiment believes that this may not necessarily be true of the writings of first-year college students. To test his theory, he asks you to write a
Hint: Use an integer array of size 128, and use the ASCII values of letters to index into the array to store and retrieve counts for the letters.

- A positive integer greater than 1 is said to be prime if it has no divisors other than 1 and itself. Write a program that asks the user to input an integer greater than 1, then display all of the prime numbers that less than or equal to the number entered. The program should work as follows: • Once the user has entered a number, the program should display an array with all of the integers from 2 up through the value entered. • The program should then use a loop to step through the array. The loop should pass each element to a method that displays the element whether it is prime number. Your result should look like, for example: Enter an integer greater than 1: 9 2, 3, 4, 5, 6, 7, 8, 9 2 is prime 3 is prime 4 is not prime 5 is prime 6 is not prime 7 is prime 8 is not prime 9 is not prime Using java programmingarrow_forwardThe local driver’s license office has asked you to create an application that grades the written portion of the driver’s license exam. The exam has 20 multiple-choice questions. Here are the correct answers: B D A A C A B A C D B C D A D C C B D A Your program should store these correct answers in an array. The program should read the student’s answers for each of the 20 questions from a text file and store the answers in another array. (Create your own text file to test the application.) After the student’s answers have been read from the file, the program should display a message indicating whether the student passed or failed the exam. (A student must correctly answer 15 of the 20 questions to pass the exam.) It should then display the total number of correctly answered questions, the total number of incorrectly answered questions, and a list showing the question numbers of the incorrectly answered questions.

- Language is C++ Lab10B: Binary Bubbles. Binary search is a very fast searching algorithm, however it requires a set of numbers to be sorted first. For this lab, create an array full of 11 integers which the user will generate. Like in the previous lab, assume that the values will be between -100 and +100. Then, using the sorting algorithm called BubbleSort, put the array in the correct order (from lowest to highest number). After this, please printthe array to the screen. Finally, search the array for the target value using Binary Search.The BinarySearch code will implement the algorithm described in the lecture slides. During this, you should print out a few key values which help Binary Search function. For example, this algorithm focuses on a low, mid, and high which correspond to the indices in the array the algorithm is currently considering and searching. Printing these values during the search process will help with debugging and fixing any issues. • BubbleSort sorts the array…arrow_forwardAskForNumbers Declare an integer array locally with the size of 200. Create a program that asks the user how many numbers the have. Use your getChoice() function from before. Make sure it does not exceed 200 as the locally declared array has the size of 200 Use a for loop and ask the user to enter each value that must be stored in the array Use a second loop to display each number, and also determine the average of all values in the array After the for loop, display the average of all numbers. This program will let you enter a list of numbers into an array. It will then display all of the numbers, and finally display the average of all numbers. How many numbers would you like to enter?5 Please enter a number: 22 Please enter a number: 33 Please enter a number:44 Please enter a number: 55 Please enter a number: 66 lumber 1 is 22 lumber 2 is 33 lumber 3 is 44 lumber 4 is 55 lumber 5 is 66 The average is 44arrow_forwardMultiple Frequencies. In the last assignment, we calculated the frequency ofa coin flip. This required us to have two separate variables, which we used to record the numberof heads and tails. Now that we know about arrays, we can track the frequency of all numbers ina randomly generated sequence.For this program, you will ask the user to provide a range of values (from 1 to that number,inclusive) and how long of a number sequence you want to generate using that number range.You will then generate and save the sequence in an array. After that, you will count the numberof times each number occurs in the sequence, and print the frequency of each number.Hints: You can use multiple arrays for this assignment. One array should hold thenumber sequence, and another could keep track of the frequencies of each number.Sample Output #1:What’s the highest number you want to generate?: 5How long of a number sequence do you want to generate?: 10Okay, we’ll generate 10 number(s) ranging from 1 to 5!1,…arrow_forward

The Lo Shu Magic Square has the following properties: The grid contains the numbers 1 – 9 exactly The sum of each row, each column and each diagonal all add up to the same number. This is shown below: Write a program that simulates a magic square using 3 one dimensional parallel arrays of integer type. Do not use two-dimensional array. Each one the arrays corresponds to a row of the magic square. The program asks the user to enter the values of the magic square row by row and informs the user if the grid is a magic square or not.
