WebbHere is a C++ program to multiply two matrices. In this program, we will multiply two matrices of size M X N and store the product matrix in another 2D array. Points to Remember. Let A, B, and C be M X N matrices, and let 0 denote the M X N zero matrix. Two matrices A (M X N) and B (P X Q) can be multiplied if and only if N is equal to P.
