Write a program that inputs the number of rows and columns from the user. It then inputs the elements to store in the matrix. The program calculates the product of each row and each column and displays on the screen. If it is a square matrix, it also calculates the sum of diagonal elements and displays it on screen.

(Statistics) a. Write a C++ program that reads a list of double-precision grades from the keyboard into an array named grade. The grades are to be counted as they’re read, and entry is to be terminated when a negative value has been entered. After all grades have been input, your program should find and display the sum and average of the grades. The grades should then be listed with an asterisk (*) placed in front of each grade that’s below the average. b. Extend the program written for Exercise 1a to display each grade and its letter equivalent, using the following scale: Between90and100=AGreaterthanorequalto80andlessthan90=BGreaterthanorequalto70andlessthan80=CGreaterthanorequalto60andlessthan70=DLessthan60=F

Solving system of linear equations with two variables using Cramer’s rule. In mathematics, the coefficients of linear equations are represented in the form of matrices. You’re required to automate all these steps by writing a program in C++ using two-dimensional arrays where required. Ask user to enter elements for coefficient matrix D and constant column C. Once the D and C are populated you should perform all steps above and display the values for x and y to the user. Note that in the case of a singular matrix, display a message for the system of equations can’t be solved.Rubrics:• The elements of coefficient matrix and constant column must be taken dynamically• Use of single structure of nested loop to find both x and y matrix• Use of single structure of nested loop to find the determinant of both x and y matrix
Please code in C Pascal’s Triangle Version 2 The Pascal triangle can be used to compute the coefficients of the terms in the expansion (a + b)n. For example, (a + b)2 = a2 + 2ab + b2 where 1, 2, and 1 are coefficients. Write a C program that creates a two-dimensional matrix a representing the Pascal triangle of size n. For example, a Pascal triangle of size 10 is shown below:
Q5. Write a program that reads from the user an integer matrix with 10x10, and then rotate that matrix 180° (UPSIDE DOWN) after that, calculate the sum and the average of the main diagonal. Print the matrix after the rotation and the values of the sum and the average of the main diagonal.
Write two functions using the following headers:int generate01()void printMatrix(int n)The first function generates and returns a random number either 0 or 1.The second function prints an n-by-n matrix. Each element of the matrix is using the number generated by thefirst function.Write a test program that prompts the user to enter n and uses printMatrix to display an n-by-n matrix. Hereis a sample run:Enter n: 30 1 00 0 10 0 0
O'caml Sliding tiles (35%) The mechanics described in this exercise can be used to implement a game sliding tiles. For basic description of the game see https://en.wikipedia. org/wiki/Sliding_puzzle. 1. Create a type slidingTile, consisting of a char matrix and two integers x and y. The integers x and y are the coordinates of an empty tile. 2. Create a function val slide : slidingTile -> int -> int -> slidingTile = that given a slidingTile and two integers, that represent a location in the matrix, it slides the tile from the specified location to the empty tile, then returns the altered slidingTile. If provided location is not adjacent to the empty tile, or out of bounds, then return the slidingTile unaltered. 3. Create a function val print_tile : slidingTile -> unit = that prints a slidingTile on screen with the corresponding characters from the matrix. However, print an empty space where the empty tile is instead.
Q.No.3. You are given a matrix of 3 rows and 4 columns. (implemented as a two dimensional array of type integer “int x[3] [4]”), you are required to write main and functions in C++ to do the following: A main function which inputs integer values from user and stores them in the array, then calls two functions display_row_sum( ) and display_column_sum( ). Function display_row_sum( ) gets the two dimensional array as argument and finds out the sum of each row and displays it separately. Function display_column_sum( ) also gets the two dimensional array as argument and finds out the sum of each column and displays it separately. So for the following array: 2 4 6 8 1 2 3 4 10 20 30 40 we might get: Sum of Row 1 = 20 Sum of Row 2 = 10 Sum of Row 3 = 100 Sum of Column 1 = 13 …… and so on
