Explanation of Solution
Two-dimensional array:
A two dimensional array is also called as a multi-dimensional array; a multidimensional array is that all the identical arrays are put together into a single array.
- This is useful for storing same type of multiple sets of data in same place.
- The main advantage is that one-dimensional array can hold only one set of value, whereas, two-dimensional array can hold multiple sets of data in the form of rows and columns.
- The structure of a multi-dimensional array is lookalike a table (that is combination of rows and columns); it contains same type of columns.
- The first size declarator in the two-dimensional array represents row and the second size declarator represents column.
- The two dimensional array can have multiple length fields, which holds the number of rows...

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…

- (Electrical eng.) Write a program that declares three one-dimensional arrays named volts, current, and resistance. Each array should be declared in main() and be capable of holding 10 double-precision numbers. The numbers to store in current are 10.62, 14.89, 13.21, 16.55, 18.62, 9.47, 6.58, 18.32, 12.15, and 3.98. The numbers to store in resistance are 4, 8.5, 6, 7.35, 9, 15.3, 3, 5.4, 2.9, and 4.8. Your program should pass these three arrays to a function named calc_volts(), which should calculate elements in the volts array as the product of the corresponding elements in the current and resistance arrays (for example ,volts[1]=current[1]resistance[1]). After calc_volts() has passed values to the volts array, the values in the array should be displayed from inside main().arrow_forward(Data processing) Write a program that uses an array declaration statement to initialize the following numbers in an array named slopes: 17.24, 25.63, 5.94, 33.92, 3.71, 32.84, 35.93, 18.24, and 6.92.

Using a for loop, input values for the current and resistance arrays. The entries in the volts array should be the product of the corresponding values in the current and resistance arrays (sovolts[i]=current[i]resistance[i]). After all the data has been entered, display the following output, with the appropriate value under each column heading: CurrentResistance Voltsarrow_forward(Data processing) Write an array declaration statement that stores the following values in an array named volts: 16.24, 18.98, 23.75, 16.29, 19.54, 14.22, 11.13, and 15.39. Include these statements in a program that displays the values in the array.arrow_forward(Statistics) Write a program that includes two functions named calcavg() and variance(). The calcavg() function should calculate and return the average of values stored in an array named testvals. The array should be declared in main() and include the values 89, 95, 72, 83, 99, 54, 86, 75, 92, 73, 79, 75, 82, and 73. The variance() function should calculate and return the variance of the data. The variance is obtained by subtracting the average from each value in testvals, squaring the values obtained, adding them, and dividing by the number of elements in testvals. The values returned from calcavg() and variance() should be displayed by using cout statements in main().arrow_forward
