c++ Lab9A: N by NNow we have moved from 1-D arrays onto 2-D arrays; please keep in mind that while with 1-D arrays weused one for-loop to traverse the array, with 2-D arrays we need to use a nested for-loop to traverse it.Ideally, a rule of thumb, is that the outer loop (the “i" loop) would be representative of the row number,and the inner loop (the "j" loop) would be representative of the column number. Together the row numberand column number decide what cell is being executed on.Create a simple program that asks the user for a row and column size for a 2-D integer array, have theprogram then create such an array. At this point this array's cells should be filled with zeros sincenothing has been done to change the cell values.Next, have that program dynamically adapt to the sizes of the array (that were provided by the user) andfill the array with numbers ascending from 1 →n (n being the number of the nth cell in that 2-D Arraydepending on the size). Please then print the array out. Remember, you cannot just print an arrayout, you have to use loops and print each cell individually.Please refer to the sample output below for visualization and match its style. Sample Output #1:Please enter the number of rows: 4Please enter the number of columns: 4I have 4 rows and 4 columns. I need to fill-up 16 spaces.The 4x4 array:1|2|3|4|5|6|7|8||9|10|11|12|13|14|15|16||Sample Output #2:Please enter the number of rows: 3Please enter the number of columns: 2I have 3 rows and 2 columns. I need to fill-up 6 spaces.The 3x2 array:1|2|3|4|5|6|

Debugging challenge: Consider the code example below. This program is designed to compare the contents of two arrays: if they are equal, the program should display "TRUE," if the arrays are not equal, the program should display "FALSE". However, even when the arrays have the same value, the program always prints "FALSE", regardless of the values in arrays a and b. What is going on here? What about the program causes the comparison to always fail? int a[4] {1, 2, 3, 4}; int b[4] = {1, 2, 3, 4}; if (a == b) { display ("TRUE"); else { display ("FALSE");
Assignment Write a program that reads a 2D array of chars, checks, and corrects each char within this array, and print out the corrected 2D array. First the program will read the row count (rowCount) and column count (columnCount) of the 2D array, both as int values. Then, the chars constituting the 2D array will be read on a row-by-row basis. After reading the 2D array, the program will check and correct each char within the 2D array according to the rules below. This process MUST be done by using a void function by sending the appropriate cell of the 2D array with a call-by-reference fashion. • If the row index is an even number, a char can only be a lowercase English value. • If the row index is an odd number, a char can only be ?, 7', or X'. • Any incorrect value MUST be changed into Finally, the checked and corrected 2D array will be printed out to the screen. NOTE: Checking the correctness of a char and correcting it (if necessary) MUST be done in the function with a…
initialise a variable named Min and set its value equal to first item of array. start a for loop to iterate through every element of marks array. check if item<Min. if 4 is true: set Min = item, else continue after the loop will finish, Min variable will have lowest marks For total marks for all the students. initialise a variable named Sum and set its value equal to zero. start a for loop to iterate through every element of marks array. for every iteration, do sum = sum+item after the loop will finish, sum variable will have total marks of all students The overall average. initialise a variable named Sum and set its value equal to zero. initialise another variable count =0. start a for loop to iterate through every element of marks array. for every iteration, do sum = sum+item, and increase count by 1. after the loop will finish, sum variable will have total marks of all students and count will have total count of marks. 5. to calculate average, do average = sum/count.
Please do not give solution in image format thanku Create a test program that creates 4 array lists. Make use of the random function and place 8 (matching/pairs of) different int values in the four lists. Remember the objective of the game is to find matching pairs so you must make sure that each value you enter has got another matching value. But it will also create problems if a value is entered more than 2 times in the 4 lists. Hint make use of getCount. (10) Test the methods created and the working of the placement of the default values.
1. initialise a variable named max and set its value equal to first item of array. 2. start a for loop to iterate through every element of marks array. 3. check if item> max. 4. if 4 is true: set max = item, else continue 5. after the loop will finish, max variable will have maximum marks
Java Objective:Design and implement simple matrix manipulation techniques.Details:Your java program should use 2D arrays to implement simple matrix operations.Your program should do the following:• Read the number of rows and columns of a matrix M1 from the user. Use an input validation loop to make sure the values are greater than 0. • Read the elements of M1 in row major order• Print M1 to the console; make sure you format as a matirx• Repeat the previous steps for a second matrix M2• Create a matrix M3 that is the transpose of M1 and print it to the console• Check if M1 and M2 can be added (should have the same dimensions). If possible, add M1 and M2 and print the result to the console. Otherwise print an error message.• Multiply M1 and M2 if possible and print to the console. If the matrices cannot be multiplied, print an error message.

C++ Coding: Arrays Implement a 4x4 two-dimensional array of integers. Use a nested loop to populate the array with random values 0 to 100 inclusive. Use a nested loop to output the array as a grid. Use a single loop to output all elements in the third row. Use a single loop to output all elements in the first column. Use a single loop to output all elements in the first diagonal (r==c). Use a single loop to output all elements in the opposing diagonal. Example Output: 10 75 67 8820 66 55 4831 57 93 3943 76 81 71Row 3: 31 57 93 39Col 1: 10 20 31 43Diagonal 1: 10 66 93 71Diagonal 2: 88 55 57 43
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

Correct answer will be upvoted else Multiple Downvoted. Computer science. assume mid=⌊max(array)+min(array)2⌋, where max and min — are capacities that track down the maximum and the base array components. At the end of the day, mid is the amount of the maximum and the base component of array separated by 2 adjusted down. Then, at that point, the array is parted into two parts left and right. The left array contains all components which are not exactly or equal mid, and the right array contains all components which are greater than mid. Components in left and right maintain their relative control from array. During the third step we pick which of the left and right arrays we want to keep. The picked array replaces the current one and the other is permanently discarded. You want to assist Mike with discovering the aftereffects of q beauty tests. Note that you test the attractiveness of the array a, so you start each beauty test with the primordial (initial) array a.…
