Concept explainers

Passing Array as Argument

An array is a data structure that holds only fixed-size data and its contents are arranged in contiguous memory slots. The primary purpose of using an array is to store data items of the identical type together. An array can stockpile any one of the following types of data: int, float, char and so forth. The elements are stored from index 0, and the difference between the two indexes of the array is termed as an offset. The array has a fixed size. Once the size is defined during array declaration, it cannot be changed later.

Question

int lastElement = num[num.length];
int lastElement = num[num.length-1];
int lastElement = num[length];

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…

Problem2 Write a program that display the position of a given element in an array. You should print the index (i.e. the position) of the element. If the element appears more than one time than you should print all its positions. The size of the array should be entered by the user. If the element does not occur then you should display element not found. Sample1: Enter the size of the array: 5 Enter an array of size 5: 44 5 13 44 67 Enter the element to find: 44 44 is found at position 44 is found at position 44 occurs 2 time(s) Sample2: Enter the size of the array: 4 Enter an array of size 4: 12 150 17 20 Enter the element: 18 18 is not found
