Exercise on Pointers

In an earlier exercise (in the Complex Data Types section), we saw how to print a matrix and how to multiply two matrices. But the size of the matrix was a fixed constant. Now, we want to accomplish the same using a matrix that’s created using dynamic memory allocation, so that the number of rows and columns of the matrix are passed as variables to a function createMatrix.

Question

Complete the definitions of the functions createMatrix, destroyMatrix, printMatrix, and matrixMult provided below.

Note: For the printMatrix and matrixMult functions, you may make minor modifications to the solution seen in the earlier exercise.
