Chapter 7.2, Problem 7.9CP
Program Plan Intro
Array:
An array is defined as a group that consists of similar data types.
- The array size must be specified by an “int” value and not long or short.
- In Java, all arrays are allocated dynamically.
- An array is always indexed, starting from 0.

Look at the following statements:int[ ] numbers1 = { 1, 3, 6, 9 };int[ ] numbers2 = { 2, 4, 6, 8 };int result;Write a statement that multiplies element 0 of the numbers1 array by element 3 of the numbers2 array and assigns the result to the result variable.
An array definition reserves space for the array.
true or false
Largest/Smallest Array Values
Write a program that lets the user enter 10 values into an array. The program should then display the largest and smallest values stored in the array.
Do question 7(above) again this time using 5 functions.
void getValues(int [], int);
void displayValues(const int[], int);
int largest(const int[],int);
int smallest(const int[],int);
void displayLargestSmallest(int,int);

- Movie Data Write a program that will be used to gather statistical data about the number of movies college students see in a month. The program should ask the user how many students were surveyed and dynamically allocate an array of that size. The program then should allow the user to enter the number of movies each student has seen. It should then sort the scores and calculate the average. Modularity: Main: The main function should accept the number of students from the user and dynamically create an array large enough to contain number of movies watched for each student. Input validation: The number of students should be a positive integer. Print the average and free the allocated array when complete. Get the data: This function should get the number of movies watched by each college student. Input validation: The number of movies should be a positive integer. Sort the data: This function should sort the array in ascending order.

- Programming: Multi-Array Assignment Instructions Overview Using a two-dimensional array, you will create the game battleship using a text file that contains the board. The user will enter coordinates to try and find ships and sink them. Instructions Imagine you are using a two-dimensional array as the basis for creating the game battleship. In the game of battleship, a `~' character entry in the array represents ocean (i.e., not a ship), a `#' character represents a place in the ocean where part of a ship is present, and a `H' character represents a place in the ocean where part of a ship is present and has been hit by a torpedo. Thus, a ship with all `H' characters means the ship has been sunk. Declare a two-dimensional array that is 25 x 25 that represents the entire ocean and an If statement that prints "HIT" if a torpedo hits a ship given the coordinates X and Y. Create a text file of 25 line. Each line has 25 characters. ~ represents water and # represents part of…arrow_forwardProgramming: Multi-Array Assignment Instructions Overview Using a two-dimensional array, you will create the game battleship using a text file that contains the board.
