multiplication of matrices

Question

please help me wih this code in C++ . i am not getting it right.

Answer 1

C++ doesn't come with built-in matrix functionality, and while multi-dimensional arrays are similar, they aren't matrices. However, while C++ doesn't have matrices built-in, the Boost libraries do come with matrix functionality.
