I'm new to c++ and was wondering how to sort a 2 dimensional array. I'm
using a select sort for 1 dimensional arrays but it is not working for a 2
dimensional array. The 2 dimensional array are float elements. Thanks in
advance
You don't specify anything at all about what you expect the results to be
after sorting your 2D array. I'm not sure exactly what it means to sort a
2D array!
You can easily sort each row (or column, whatever), but then what? Must
every element in the next row be greater (or less) than every element in the
preceding row? Or is there some other criteria for what you desire? Is it
a sparse array? Are elements allowed (or supposed) to move between columns
as well as rows? See my problem? If you have a clear definition of the
problem and its restrictions, the answer will likely be easy to see.
Try working a small example on paper first, and that may help.
By the way, this is not so much a C++ question as an algorithm question.
Once you have a design, and implement it in C++ code, we can surely help you
correct that code if it's giving you problems. But we can also help point
you in the right direction initially, provided we have enough info.
