C++

Write a program that performs the addition of two matrices A and B of the same dimensions N and M. Recap: a b c d (a' b c d (a + a' b + b c + d + d' e f g h +le' f' g' h' = e+e' f+f' g+g' h+h' i i k li' j' k' i +i' j+j' k +k' 1+l' 1. The result of the addition will be stored in a third matrix C which will then be displayed. 2. Matrix B is added to A
