- Please solve and show steps, work, and information related to this problem. Thank you. The following C++ code performs a set of various arithmetic operations using both pointers and references: Fill in a memory table that shows the final values for both function a and function b. Indicate the final values of each parameter, passed in variable(s), and the return value of the function. Provide a separate copy of this memory table for each function.Write a C++ function to find the norm of a matrix. The norm is defined as the square root of the sum of squares of all elements in the matrix Note: the use of pointers is not allowed and code should be simple.The user should input the matrix he wants.We cannot initialize the matrix on our own.7. using c++, Write a void function that accepts an integer array a and a integer SizeA, and an integer n, and adds n to every element in that array. Be sure to develop an appropriate name for your function.
- (a) Write the C++ function, operator+(const Matrix& b) const, which returns the matrix *this + b.Define what the following do in C in relation to pointers: *, &, [], +, Note that there are 2 functions for *. Write code that uses all 5.Write a programme in c that will substrate 2 matrix and print the output matrix.Matrix will be 4 by 4 matrix.Take the elements of the first matrix from the user as input.Then transpose the first matrix to create the second matrix and substrate transpose matrix from the first matrix.Use function prototype : Void subtractMatrix( int rowsize,int colsize,int matA[rowsize][colsize],int matB[rowsize][colsize])
- Write a C++ function that takes two integer arrays and adds each element of both arrays using pointers not by index and function must check the array size to ensure same number of elements.Write a program in C++ of how to use two-dimensional dynamic arrays. Follow the instruction below; - Declare the function of fill and print - Create main function and include your information details - Declares 'board' to be a pointer to a pointer of type int - Declare the 'rows' and 'columns' as integer variables - Prompt user to enter the number of rows and colums - Get the user input of rows and colums - Create the rows of board - Create the columns of board - Insert elements into board - Print the elements of boardProblem Statement: Consider an input string TAM of letters ‘A’, ‘M’, and ‘T’. This string, which is given by the user, ends with ‘#’. It should be stored in a table (or array), called TAMUK. The number of each of these letters is unknown. We have a function, called SWAP(TAM,i,j), which places the ith letter in the jth entry of string TAM and the jth letter in the ith entry of TAM. Note that SWAP(TAM,i,j) is defined for all integers i and j between 0 and length(TAM)–1, wherelength(TAM) is the number of letters of TAM. Using our algorithmic language, write an algorithm, called Sort_TAM, which sorts the letters in the array TAMUK in a way that all T’s appear first, followed by all A’s, and followed by all M’s. The algorithm Sort_TAM should have one parameter: The array TAMUK. Also, your solution is correct only if the following four constraints are satisfied: - Constraint 1: Each letter (‘A’, ‘M’, or ‘T’) is evaluated only once. - Constraint 2: The function SWAP(TAM,i,j) is used…
