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

1- Write a user-defined function that accepts an array of integers. The function should generate the percentage each value in the array is of the total of all array values. Store the % value in another array. That array should also be declared as a formal parameter of the function. 2- In the main function, create a prompt that asks the user for inputs to the array. Ask the user to enter up to 20 values, and type -1 when done. (-1 is the sentinel value). It marks the end of the array. A user can put in any number of variables up to 20 (20 is the size of the array, it could be partially filled). 3- Display a table like the following example, showing each data value and what percentage each value is of the total of all array values. Do this by invoking the function in part 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];

The following definition has errors. Locate as many as you can. A) int size;    double values[size];B) int collection[-20];C) int hours[3] = 8, 12, 16;

C++ 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.

Question 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 average
