Using C++.

Write a multithreaded program using SDL threads or POSIX threads. the program uses a number of threads to multiply two matrices. the multiplication of an MXL matrix A and an L X N matrix B gives an MXN matrix C, and is given by the formula, Basically, each element C_ij is the dot product of the i-th row vector of A with the j-th column vector of B. the program uses one thread to calculate a dot product. Therefore, it totally needs MxN threads to calculate all the elements of matrix C
