Thread: Question on reading matrices from file

Ok, I am supposed to read the input from a file that holds info where the matrix dimensions are given, followed by the actual values of each matrix separated by spaces

Code:

3 - Rows of first matrix
4 - Cols of first matrix
8 2 0 1
6 7 2 9
3 6 1 7

4 - Rows of second matrix
2 - Cols of second matrix
5 6
9 2
1 7
0 6

My question is, is there a way to differentiate between what is the dimensions, and what are the values of the matrix.

Also, I imagine the best way to know I am moving on to the 2nd matrix is once I have looped through the dimensions of the first?

In the end I am multiplying the two, but I THINK I have that part down, because if I ask the user for each individual input, it works.

Hope this makes sense, Thanks in advance.

You know the first two numbers are the dimensions, then you have to read (mxn) numbers for the data, then two numbers for dimensions, then (mxn) numbers for data, ....
