A: Pogram code #1:
Determine whether the follwing array declarations are valid, if a declaration is invalid, explain why:
d. double[-50] ratings[];
e. string flowers[35];
f. int SIZE = 10;
double sales[2 * SIZE];
g. int MAX_SIZE = 50;
double sales[100 - 2 * MAX_SIZE];
(d)
The declaration is invalid due to multiple reasons. Firstly the array size should be specified after the array name, secondly the array size has to be a positive number. The correct declaration is double ratings[50];
(e)
The declaration is valid.
Step by step
Solved in 2 steps
- Determine whether the following array declarations are valid. If a declaration is valid, write VALID. If it is invalid, you can make assumptions and write a correct declaration. a) int x, y; char[x][y] board = new board[][]; b) int size; double[] list = new double[size]; c) int[] test = new int[-5]; d) double[] sales = new double[25.5]; e) int[50] list;Determine whether the following array declarations are valid. If a declaration is invalid, explain why. a. int list[61];b. strings names[20];c. double gpa[];d. double[-50] ratings[];e. string flowers[35];f. int SIZE = 10;double sales[2 * SIZE];g. int MAX_SIZE = 50;double sales[100 - 2 * MAX_SIZE];Determine whether the following array declarations are valid. If a declaration is valid, determine the size of the array. a. int list[] = {18, 13, 14, 16};b. int x[10] = {1, 7, 5, 3, 2, 8};c. double y[4] = {2.0, 5.0, 8.0, 11.0, 14.0};d. double lengths[] = {8.2, 3.9, 6.4, 5.7, 7.3};e. int list[7] = {12, 13, , 14, 16, , 8};f. string name[8] = {"John", "Lisa", "Chris", "Katie"};
- If the following array declarations are valid, write "VALID". Otherwise, make assumptions and write a correct declaration. int[50] list; 1. int size; double[] list=new double[size]; 2. int[] test=new int[-5]; 3. double[] sales=new double[25.5]; 4. int x,y; char[x][y] board=new board[][] 5.What is the value of J[2][1] in the following array declaration? int[][] J= {{5, 10 }, {15, 20, 25}, {30, 35}}; a. 20 b. 30 c. 35 d. 15For an array declartion of int number [25];, what will be the ending index? 0 1 24 25
- Define the meaning of the following array by illustrating the array list. i. int total[10] = {0}; ii. int total[10] = {8, 5, 12}; iii. int total[ ] = {5, 6, 3}; iv. total[2] = 3; v. int total[4] = {1, 2, 3, 4};Code an exam in Java that repeatedly asks the user to enter the capital for a province in Canada. Then, the program should report whether the answer is correct. Eventually, you must display how many answers the user guessed correctly.The requirements are as follows: - Use a 2D array to hold the provinces and their capitals (as implied by the table below)- Answers are not case-sensitive (e.g. Toronto and tOrOnto are considered the same)Determine whether the following array declarations are valid. If a declaration is invalid, explain why. (1, 2) A) int primeNum [99]; Valid B) int testScores [0]; C) string names [60]; D) int list100 [0..99]; E) double [50] gpa;
- 5.24 LAB: Shift right (JAVA) Write a program in java that reads a list of integers from input into an array and modifies the array by shifting each element to the right one position and by shifting the last element to the first position. The input begins with an integer indicating the number of values that follow. Output the modified array and end with a newline. Ex: If the input is: 6 2 4 6 8 10 12 the output is: 12 2 4 6 8 10 For coding simplicity, follow every output value by a space, including the last one. Code starts here: import java.util.Scanner; public class LabProgram { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); int[] userValues = new int[20]; // List of integers from input /* Type your code here. */ }}in java Declare and initialize an array with 8 integer elements. Use therandom method of the Math class to initialize the values with randomintegers between 1 and 50 (exclude 50) and print each of them onConsole.Write the pseudocode that will populate an array of type string with data.The array is called dogBreeds and the following values must be loaded: Labrador, Poodle, Terrier, Spanniel, Doberman
