Here's a Python program that multiplies two matrices using arrays (lists of lists):

def matrix_multiplication(matrix1, matrix2):
rows1 = len(matrix1)
cols1 = len(matrix1[0])
rows2 = len(matrix2)
cols2 = len(matrix2[0])

if cols1 != rows2:
print("Matrix multiplication not possible.")
return None

result = [[0 for _ in range(cols2)] for _ in range(rows1)]

for i in range(rows1):
for j in range(cols2):
for k in range(cols1):
result[i][j] += matrix1[i][k] * matrix2[k][j]

return result
