In this program we compute addition of two matrices A and B which has same order. First we ask user to enter order or size of matrix, then enter numbers for matrix A and B. To understand the strategy, let us have look at the dummy matrices. Suppose matrices have order 3×3.

Matrix A :
3 7 3
9 1 4
0 2 6
Matrix B :
8 3 5
4 2 0
7 5 8
Resultant Matrix is addition of matrices A and B :
11 10 8
13 3 4
7 7 14
