Matrix Multipliion in C++ | Multiply 2d Array

Follow is the program ofmultipliionof matrix in c++. we multiplymatrix'sby rows of firstmatrixwithcolumnof second matrix and store result in third matrix also shown in figure. Formultipliionof matrix it is necessary that row of first should be equal tocolumnof second matrix.
