Write a program that prints at least 10 characters of your name (last, first) in uppercase at the terminal. Use a n by m array (i.e., a two dimensional array, with n (=7) as size of the first dimension and m (=10) as the second dimension) to represent each oversize letter. C++, the name is "Krish"
I need help with creating a Java program described below: Minesweeper.Write a program that reads three numbers, m, n, and p and produces an m-by-n Booleanarray where each element is occupied with probability p. In the minesweeper game, occupiedcells represent bombs and empty cells represent safe cells.Print out the array using an asterisk for bombs and a period for safe cells.Then, create an integer two-dimensional array with the number of neighboring bombs (above,below, left, right, or diagonal). * * . . . * * 1 0 0. . . . . 3 3 2 0 0 . * . . . 1 * 1 0 0Write your code so that you have as few special cases as possible to deal with, by using an(m+2)-by-(n+2) Boolean array.
An array having a character subscript can be indexed using a computer language, as in CHR_ARRAY['A':'D']. In this scenario, the characters' ordinal numbers (ORDs), such as ORD('A') = 1, ORD('B') = 2, ORD('Z') = 26 and so on, are used to designate the array's elements, CHR_ARRAY['A'], CHR_ARRAY['B'], and so on. Beginning at position 500, two arrays called TEMP[1:5, -1:2] and CODE['A':'Z', 1:2] are now kept in the RAM. Furthermore, CODE outperforms TEMP in storage. Determine the locations of the following addresses: (i) TEMP[5, -1], (ii) CODE['N',2], and (iii) CODE['Z',1].

By using JavaScript find the sum of all the elements of a given array (before removing and after removing) and removes the last element from an array? [2, 3, 4, 6, 30, 23] Answer it as soon as possible to get the upvot.
Create a 2D array of size 14x14 having same values ranging from 0 to 255 in each row. You are free to specify the values of this array. For instance, consider a 3x3 array as;Array [3] [3]= {{12,12,12}, {75, 75, 75}, {247, 247, 247}}12, 75, and 247 pixel values are specified in a way that they are in a range of 0 to 255 and they are same in a row.Write a code namely arraytoimage.c using any pgm (portable gray map) format image that represents an image in a text file in which each pixel is represented by a number ranging from 0 and 255. In this code, write:-P2 (magic number)-Width and height of the image-Maximum grayscale value-Gray scale intensity values you specify in the arrayin an order to this image
How to write a program in java that ask the user to input an int size value into a 2d array, then output a table of random 0 and 1 of that size (table must be a perfect square), then output the fraction of your array that is ones and the fraction that is zeros, then output the sum for each row, the sum of colunms and which row and colunm have the largest sum, then determine if the largest row sum is greater than the largest column sum or vice versa, then output the sum of the diagonal(the diagonal starting at location [0][0] and going down to [N-1][N-1] for an array of size N) and determine if the diagonal sum is greater or equal to the largest row sum and greater than or equal to the largest column sum? output should look similar to screen shot
Suppose that longitude is assigned to the first column of an array and latitude is assigned to the second column of an array. If the user inputs the longitude and the latitude, how do you loop through the 2D array to find which row the longitude and latitude match up? Please use java to answer this question. Here are the variables: double longitude = Double.parseDouble(args[0]); double latitude = Double.parseDouble(args[1]);
Write a program that displays your first initial as a capital letter using an 8x8 array of blocks C programming. (my initial SA,) you must use at least one other color than black and white for at least one of your letters. This other color can be used either for the foreground or the background so I have the code I just need help with the cordinates of pixels letter S and A (7,0) is top left also could you do them separately
