I'm having some trouble knowing where to start with this code, any help would be appreciated

Instructions For this lab, your task is to first define a NxM matrix (e.g. two-dimensional array). Then you should prompt the user to enter the values for the matrix. Your program should be able to work with any values of N and M (i.e. declare N and M, or more clearly stated, your ROWS and COLUMNS as constants at the beginning of your program). Once the user has entered in all the values, print the matrix back to the user. Be sure to align the values so the matrix is easily readable by the user. Now define a new matrix of size MxN to represent the transpose. Store the transpose of the user's matrix and then print the transposed matrix to the user
