For these three arrays: int A[4][3] = {4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48} and int B[4][3] = {5, 8, 11, 14, 17, 20, 23, 26, 29, 32, 35, 38} Rewrite A and B in row by column format and...

For these three arrays:

int A[4][3] = {4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48} and

int B[4][3] = {5, 8, 11, 14, 17, 20, 23, 26, 29, 32, 35, 38}

Rewrite A and B in row by column format and perform the following operation on A and B:

int C[4][3] = A[4][3] + 2*B[4][3].

Then the value in C[2][1] is:  _______
