Addition of Two Matrix

Using the functions of task 2 to create another 2-D array of user defined size. Add this
2-D array to the 2-D array created in task 2 and store the result in 3rd 2-D array. Be careful
because both the arrays may be of different sizes so the 3rd array should be able to hold
the result properly
