write a function to add two matrices, and (b) and save the result in . The function should accept the two matrices as parameters and return their addition through the use of a 3rd parameter. reference parameter for the output matrix. Note that by default, arrays are pass by pointer, which works similarly to pass by reference, except there is no extra syntax (&) needed when defining the parameter. We will learn more about pointers later in this course (enazz an)-(bu ha ha)-(11+b a11 a12 a13b b2 bi3 021 a22 a23 a31 a32 a33/ Each element cy is aj+ bi, Write a test program that prompts the user to enter two 3 x 3 matrices and displays their addition.
