Program Plan Intro
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.
- Each row in the two dimensional array has a length field which holds the number of columns.
Syntax:
The syntax of two dimensional arrays is as follows:
datatype array_name [number_of_rows][number_of_columns];
From the given syntax, a two-dimensional array named “grades” of type “int” has been created with 30 rows and 10 columns.

Using C# in Microsoft Visual Studio Create an application that simulates a game of tic-tac-toe. The application should use a two-dimensional int array to simulate the game board in memory. When the user clicks the New Game button, the application should step through the array, storing a random number in the range of 0 through 1 in each element.The number 0 represents the letter O, and the number 1 represents the letterX. The form should then be updated to display the game board. The application should display a message indicating whether player X won, player Y won, or the game was a tie.

- (Electrical eng.) Write a program that specifies three one-dimensional arrays named current, resistance, and volts. Each array should be capable of holding 10 elements. 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(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(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.
