I am working on a project that requires me to build a program that simulates particle aggregation. I have built the program. However when run on a windows machine it crashes for larger array size and number of particles. on linux machine for large numbers it runs for long time and eventually fails.
randwalk.c
the program crashes in the for loop beginning line 107 occasionally in the one begining 34. Any hints and tips would be great . Thinks guys
Part of your problems may be being caused by the following:

It's called "use after free"Code:for(i=0 ; i<N ; i++) { free(X[i]); } free(X); ..... for( i=0 ; i<N ; i++ ) { for( j=0 ; j<N ; j++ ) { if( X[j][i]==1 )
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
I have fixed the errors given and it still crashes i'm going through right now working out whats stopping it randwalk.c . I need to go through and tidy up as well it looks a mess ,more comments.
Good for you, Max! Code that looks a mess, is hard to study, and hard to debug.

That's funny, because your latest attachment is identical to the first one.
