Matrix Multiplication

Write code for matrix multiplication.

Answer:

(M x N) * (N x P) = (M x P) matrix
     ^^^^^^^

  N
---->
1 2 3   x 1 4 |
4 5 6     2 5 | N
          3 6 \/

From the above diagram, it can be infered that
M and P will form the outer loops and N will be the
innermost loop.

for ( i = 0 to M )
  for ( j = 0 to P )
  {
    a[i][j] = 0;
    for ( k = 0 to N )
    {
       a[i][j] += a[i][k] * a[k][j];     
         
    }
  }
