Question

I wanted to get an opinion here. Would it be possible to write a C program that deshuffles a text file? What do I mean by that? Say I have the following data in a textfile:

1  X
4  T
3  Z
2  L

And I wanted to deshuffle it and output another file as so:

1  X
2  L
3  Z
4  T

Such that all of the data following the number is preserved with the actual index number. Do know that I have 40,500 shuffled entities, so that should probably be taken into account since that could take a long time if the program needs to loop through all of the entities for each entity…And I only used letters for representation. The actual data files don’t have letters, but rather have floats. Sorry if this causes any confusion

So, bottom line, would this be possible with C? And if so, could I get a hint at where to start? I could obviously input all of the textfile data into an array dat[][], but how should I deshuffle it then?

Thanks!

I’d just use sort -n instead of writing a program.
