Write a C++ program to accept two matrices of size defined by the user (user should enter row size and column size), display their sum and difference. If size doesn't match, show an error message. Q2. Write a C++ program that accepts two arrays of same size (user required to input the size) and calculate the following: 3A-4B (where A is the first matrix and B is the second matrix) Q3. Write a C++ program that accepts two arrays of size defined by the user and calculate product of two matrices. If the size doesn't match, show an error message. Q4. Write a C++ program that accepts two arrays of size 4x4, calculate AA + 2AB and display the result, where A is the transpose of A. Q5. Write a C++ program to create a matrix that has 33 on the diagonal line, 66 in locations above the diagonal line and 11 in locations below the diagonal line. See the example given below. 33 66 66 66 11 33 66 66 11 11 33 66 11 11 11 33 Q6. Write a C++ program that accepts two arrays of size 4x4, calculate AA, ATA and display the results, where A is the transpose of A.
