This assignment is about array operations.
Create an array with 1000 items and fill it with random numbers from the range of -100, 100 (including -100 and 100). Then, your program asks user to enter a number. The program keeps running until user enters a out-of-range (-100,100) number. An example run is given below.
Enter a number: -4Frequency of -4: 54
Enter a number: 4
Frequency of 4: 15
Enter a number: 35
Frequency of 35: 8
Enter a number: 43
Frequency of 43: 2
Enter a number: 101

- In visual basic Print out the last value in a single-dimensional array.arrow_forwardJAVA ARRAY MANIPULATION QUESTION: make a method called manipulator that takes a double array as parameter and modifies it. The method will modify the array then print the array. The method must modify the existing array, it CAN NOT create a different array as the solution. The manipulator method will be a void method. Remember: To get an average of 2 digits you add them together then divide by 2. Average of x and y = (x+y)/2 Modifications the method will do: For every 2 consecutive elements in the array, both the elements are replaced by their average. If the number of elements in an array is odd don't modify the last number of the array. Basically, you find the average of 2 consecutive elements then replace both of the elements with that value. Examples: Array = {2.0,3.0} will be changed to {2.5,2.5} when passed to the manipulator method Array = {2.0,3.0,45} will be changed to {2.5,2.5,45} when passed to the manipulator method Array = {2.0,3.0,45,55} will be changed to...arrow_forwardFYI: Please write the code in Pseudocode (no programming language please) 1.

Two-Dimensional ArrayInstruction:Create a java program that generates elements (randomly from 10 – 75) of a 2-dimensional array (5x5) using the Random Class then perform the following:1) Output the array elements2) Output the sum of prime numbers in the array3) Output the elements in the main diagonal.4) Output the sum of the elements below the diagonal.5) Output the sum of the elements above the diagonal.6) Output the odd numbers below the diagonal.7) Output the even numbers above the diagonal. NOTE: Please do not use the array methods available on the internet. Use the for loop, while loop or do-while loop statement in your codes..arrow_forwardCreate Array of Random Dates In this task you are required to write a function that will generate a column array (a variable called dates) containing N random dates. N is an integer (whole number) entered by the user and will indicate to the function how many random dates the user requires. The dates array will be structured as follows: • The array shall have two columns; column 1 will contain numbers indicating the day of each month (1-31) and column 2 will contain numbers indicating the month (Jan 1, Feb=2, Mar = 3.... Dec = 12). . Each day must be randomly generated (using the randi() function) taking into account the maximum number of days in each month (i.e. Jan, Mar, May, Jul, Aug. Oct and Dec have 31 days, Apr. Jun, Sep and Nov have 30 days and Feb will have 28 days). You must use an if-elseif-else statement to decide this. • We are assuming no leap years (e. February can only have days between 1-28). For example, the output from calling the function: output = dategen (3) could...arrow_forwardProblem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive. Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations. Remember to validate the input and display an error message if the user inputs invalid data. Documentation and the screenshot(s) of the results. Example: 1 2 3 4 5 6 7 8 9 the result will be : 1 4 7 2 5 8 3 6 9arrow_forward
- Payroll Write a program that uses the following arrays: empId: an array of seven long integers to hold employee identification numbers. The array should be initialized with the following numbers: 5658845 4520125 7895122 8777541 8451277 1302850 7580489 hours: an array of seven integers to hold the number of hours worked by each employee payRate: an array of seven doubles to hold each employee's hourly pay rate wages: an array of seven doubles to hold each employee's gross wages The program should relate the data in each array through the subscripts. For example, the number in element 0 of the hours array should be the number of hours worked by the employee whose identification number is stored in element 0 of the empId array. That same employee's pay rate should be stored in element 0 of the payRate array. The program should display each employee number and ask the user to enter that employee's hours and pay rate. It should then calculate the gross wages for that employee (hours times...arrow_forwardpart a- 2point) for 3 students find the average of a student by asking him how many grades do you have. The answer to this question, determine the size of the array(list of grades) and then ask the user to enter grades(the number of the grades is equal to the size of the array) then calculate the average for each student. Hence, you will calculate 3 averages. to calculate the average, use the array accumulator. Also when you get each grade validate it. validation for grade means that you check whether a grade is between 0 and 100. if the grade is negative or a grade is more than 100 then it is not valid and you have to ask the user to enter a grade again. Part b- 1 point) Find the maximum and minimum grades for each student. Part c- 1 point) Print the sorted list of the grades for each student. example: if grades user entered are: 60 78 98 23 45 then sorted list is:23 45 60 78 98 (Array not vector)arrow_forwardWrite a program that reads student scores into an array, gets the best score, and then assigns grades based on the following scheme: • Grade is A if score is • Grade is B if score is • Grade is C if score is • Grade is D if score is • Grade is F otherwise. best - 10 best - 20; best - 30; best - 40; The program prompts the user to enter the total number of students, then prompts the user to enter all of the scores, and concludes by displaying the gradesarrow_forward
- JAVA PROGRAM: Monkey Business A local zoo wants to keep track of how many pounds of food each of its three monkeys eats each day during a typical week. Write a program that stores this information in a two-dimensional 3 ×ばつ 5 array, where each row represents a different monkey and each column represents a different day of the week. The program should first have the user input the data for each monkey, or use constant values rather than asking user for input. Then it should create a report that includes the following information: Display 3X5 array first. Average amount of food eaten per day by the whole family of The least amount of food eaten during the week by any one The greatest amount of food eaten during the week by any one Input Validation: Do not accept negative numbers for pounds of food eaten.arrow_forwardC++ c++ write a hangman game that randomly generates a word and prompts the user to guess one letter at a time, as shown in the sample run. Each letter in the word is displayed as asterisk. when the user makes a correct guess, the actual letter is then displayed. When the user finishes a word, display the number of misses and ask the user whether to continue to play with another word. Declare an array to store word as follow: Store 20 different words in a text file, read them into an array. Randomly pick a number 1..20 and use this word for the current round.arrow_forwardQuestion 1 Write a program that declares an array of 100 doubles. The program asks the user to enter a number N between 100, and then: initializes the first N elements of the array to random numbers between 1 and 100. calculates the average of these numbers and displays it. A final loop displays the elements of the array, each on a line, with an indication as to whether that number is lower or higher than the average. For example, if the numbers generated are 5, 28, 3, 8, 15, 7, 22, 6, 1, 4, then the program will print: Average = 9.9 5 28 3 8 15 7 22 6 1 4 11 11 11 -- 11 11 1- —— 11 lower than average higher than average lower than average lower than average higher than average lower than average higher than average lower than average lower than average lower than averagearrow_forward
