Question

Transcribed Image Text:2. Lottery Number Generator
Design a program that generates a 7-digit lottery number. The program should have
an Integer array with 7 elements. Write a loop that steps through the array, ran-
domly generating a number in the range of 0 through 9 for each element. (Use the
random function that was discussed in Chapter 6.) Then write another loop that
displays the contents of the array.

- FYI: Please write the code in Pseudocode (no programming language please) 1. Write pseudocode to load a single array with data. Then search that array for a match. Here are the specifics. You do NOT have to write the entire program. Load the array with data from a file named customerNumbers Ask the user to enter their customer number Search the array for the customer number If you find a match output FOUND If there is no match output NOT FOUNDarrow_forwardLw//. 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.

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_forward
- Weight Statistics Write a program that monitors monthly weight loss each of 12 months into an array of doubles. The program should calculate and display the total weight loss for the year, the average monthly weight loss, and the months with the highest and lowest amounts. Input Validation: Do not accept negative numbers for monthly weight loss.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_forward1) Given row array vals of unknown size of 2 or greater, write an expression that yields a new array containing all elements except the first. For example, if vals = [10, 20, 30, 40], the expression would yield [20, 30, 40]. vals Check Show answer 2) Write an expression that results in a row array vals shifted to the right. For example, if vals = [1, 2, 3, ....., n-1, n], then a right shift will result in [n,1,2,3,.....n-1]. Check Show answer Incorrect vals(???)arrow_forward
- Alphabet Random Walk• Write a program to generate a random walk that spans a 10*10 character array (The initial values of the elements are all.). The program must randomly walk from one element to another, moving one element position up, down, left or right each time. The elements that have been visited are labeled with the letters A through Z in the order in which they were visitedarrow_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_forwardC# Question Assume that you have an array of integers called numbers that has been declared and filled with values.

- FYI: Please write the code in Pseudocode (no programming language please) 1. Write a pseudocode that outputs the contents of parallel arrays. You do NOT have to write the entire program. The first array will hold phone numbers The second array will hold company names You do NOT need to load the arrays. Your code can assume they are already loaded with data. arrays are named phone[] and company[]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
