Write a program that reads two matrices and determines their product matrix. For example: M1 = 1 2 3 3 2 1 and M2 = 1 2 3 4 5 2 5 3 1 4 5 4 3 2 1 then P = 20 24 18 12 16 12 20 18 16 24 Requirements: Implement the following functions: void readm(matrix [] [], int rows, int cols); void writem(matrix[][], int rows, int cols); void mulmatrix(float matrixl [] [], int rowsl, int colsl, matrix2 [] [], int cols2, float product [][]); Input the row size and column size for matrix M1 and M2 Input the matrix Validate the product matrix dimension
