Write a program that performs the addition of two matrices A and B of the same dimensions R and C.

Matrix B is added to A.

\(\begin{pmatrix} a & b & c & d \\e & f & g & h \\ i & j & k & l \end{pmatrix} + \begin{pmatrix} a' & b' & c' & d' \\e' & f' & g' & h' \\ i' & j' & k' & l' \end{pmatrix} = \begin{pmatrix} a+a' & b+b' & c+c' & d+d' \\e+e' & f+f' & g+g' & h+h' \\ i+i' & j+j' & k+k' & l+l' \end{pmatrix}\)
