Output :
Enter Row & Column of Matrix A : 2 3
Enter Row & Column of Matrix B : 3 2
Matrix can be Multiplied
Input Matrix A : 1 2 3 4 5 6
Input Matrix B : 6 5 4 3 2 1
Matrix A :
1 2 3
4 5 6
Matrix B :
6 5
4 3
2 1
Multiplication of Matrix A & B :
6 8 6
20 15 6
Press any Key to Continue…………………
SAMPLE DATA 2 :
Enter Row & Column of Matrix A : 3 3
Enter Row & Column of Matrix B : 3 2
