Programming instruction: your program should read the data from a file. The file name is provided as command-line argument at execution time. The data file format is as follows: first line has 4 integer numbers, separated by single spaces, specifying dimension of two matrices. For example, 3 2 2 3 means matrix A has dimension 3 A????1 2 and matrix B has dimension 2 A????1 3. Your program should check, at the beginning, whether two matrices are eligible for multiplication (that is, the middle two
