[Exercise 20] Two-dimensional arrays: The Matrix

0 like 0 dislike

Please write a program receive 2 sets of two-dimensional arrays: a[ ][ ] and b[ ][ ]; size 3*3. Then add a value of each element from a to b for example: a[0][0] + b[0][0], a[0][1] + b[0][1] and so on. Finally, output the summation of each addition.
