Write a c++ program to compute the product of two matrices. you are required to use the template class vector to represent a matrix. (see matrix. cpp on the main course page, which is an example of how to create and initialize a 2d-matrix using vectors.) specifically, your program will include the main( ) function and a second function multiply_matrices( ). the main() function will

allow the end-users to provide the dimensionality of the two matrices a and b, and subsequently the content of a and b

call the multiply_matrices() function to compute the product of a and b

print out the multiplication result
