I have to do a programm in C on codeblocks. And I don't find algorithm which can execute what I want:
So I explain,
I must do a treatement of file, I have to read a file and create another file with some informations of the file read.
example information in the file to read:
A 16 18 A 15 13 A 22 17 A...
and I have to do a program that allow associate all numbers which not associate, for example:
A 16 18 (is a combinaison), A 15 13 (is another combinaison),...
and in the new file, I must have:
16 15
16 13
16 22
16 17
18 15
18 13

Hi there,
I can't tell you exactly how to do this, but here's what I'll think you'll need to do the job:
The letters are actually a separator for the numbers, so if you can "scan" the string character by character, you know that as long as you don't find a letter the current character should be on the same line as the previous. In pseudo code:
Hope that makes sense and will get you started.
There may be more effective ways to do this, but as it appears that your first file contains just a string (no seperate lines) I'm guessing the above is the way to go.
Another route may be to load the string and loop over a first position search of 'A', then using substring to fetch the data and strip it from the loaded string.
All the best,
NwN

filestream f;
temp string tmp;
read f character by character;
if character != A then add character to tmp
else add '\n' to tmp (for linebreak)
