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.

- CODE IN JAVA design a program that grades arithmetic quizzes as follows: (Use the below startup code for Quizzes.java and provide code as indicated by the comments) 1. Ask the user how many questions are in the quiz. 2. Use a for loop to load the array. Ask the user to enter the key (that is, the correct answers). There should be one answer for each question in the quiz, and each answer should be an integer. They can be entered on a single line, e.g., 34, 7, 13, 100, 8 might be the key for a 5-question quiz. You will need to store the key in an array called "key". 3. Ask the user to enter the student's answers for the quiz to be graded. There needs to be one answer for each question. Note that each answer can simply be compared to the key as it is entered. If the answer is correct, add 1 to a correct answer counter. need this in a separate for loop from the loop used to load the array. 4. When the user has entered all of the answers to be graded, print the number correct…arrow_forwardWrite a program that prompts the user to read two integers and displays their sum. Your program should prompt the user to read the number again if the input is incorrect. Hint: use the InputMismatchException 2-Write a program that meets the following requirements: Creates an array with 100 randomly chosen integers. Prompts the user to enter the index of the array, then displays the corresponding element value. If the specified index is out of bounds, display the message Out of Bounds Hint: use the ArrayIndexOutOfBoundsExceptionarrow_forwardProgramming in C language. RandomNumbers Declare an integer array locally with the size of 200. Create a program that asks the user how many numbers the have. Use your getChoicel) function from before. Make sure it does not exceed 200 as the locally declared array has the size of 200. Use a loop to assign random numbers from 1 to 10000 to the array elements. (Remember to use srand() to seed the random number generator). Use a second loop to display each number, and also determine the average of all values in the array. You must also find the largest and the smallest numbers. 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?10 Number 1 is 42 Number 2 is 8468 Number 3 is 6335 Number 4 is 6501 umber 5 is 9170 Number 6 is 5725 Number 7 is 1479 Number 8 is 9359 Number 9 is 6963 Number 10 is…arrow_forward

EX17:let you have array A[20], write a program that read the array and swap the content of odd index with 7/7 the content of even index .arrow_forwardThe Sports Department of an education institution collects students' names participating in various teams like cricket, football, hockey. A student is allowed to participate in only ONE team. Write a Java program that prompts the user to input names for the three teams and checks NO identical names are found in the arrays. i.e., while entering name for the second team, it should not appear in the first team and while entering name for the third team, it should not appear in first and second team.arrow_forward
- The 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. Need Visual Studio Code (C Language )arrow_forwardComputer Science Java Program Write a program in Java that takes in a user-submitted file that is a grid of 0s and 1s. Represent the grid as a two-dimensional array. Write a program that: a. computes the size of a group when a square in the group is given b. computes the numbers of different groups c. lists all groups Example: userInput.txt: 0 0 0 0 0 0 0 0 0 10 0 0 1 1 0 0 0 0 10 0 0 0 0 0 0 0 0 00 0 0 0 1 0 0 1 0 00 0 0 1 0 0 0 1 0 00 0 0 0 0 0 0 1 1 00 0 0 0 1 1 0 0 0 00 0 0 0 0 0 0 0 0 00 0 0 0 0 0 0 0 0 00 0 0 0 0 0 0 0 0 0 The program should output three things: The size of the group in which location specified by the user belongs. then if the user enters 1,2 the answer is 0 1,4 the answer is 2 3,4 the answer is 1 4,7 the answer is 4 The number of each size group Size Count 2 3 1 List of each group’s locations 1: (0,9) (1,9) 2: (1,3) (1,4) 3: (3,4) 4: (3,7) (4,7) (5,7) (5,8) 5: (4,3) 6: (6,4) (6,5)arrow_forwardA 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_forward
- Write a Java application for a grade book using arrays: Create an array to store 20 test grades, random numbers between 0-100, inclusive. Print these 20 grades Calculate and print the average grade Calculate and print the highest and lowest gradesarrow_forwardLanguage 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_forwardFYI: Please write the code in Pseudocode (no programming language please) 1.
