Advice please

Hi there.

I have to create (through a number of computational methods) a matrix of data. As an example here is one:

    A   B   C
A   0   8   9
B   8   0   7
C   9   7   0

What I need to do is store this matrix in a text file, tab-delimited.

What I would like to know is whether it would be easier to create a 2-dimensional [n][n] array first and then copy the contents of it over to the file, or form the matrix in the file directly.

Thanks

I would think not only easier, but far cleaner. Separating your I/O code and your computational code into different methods (or even different classes) will make the whole thing easier to develop.

I agree. Make sure that you have a class holding your data and later think serializing it to a file.
