Thread: sorting...

hi,

I have an array of strings and want to be able to sort them alphabetically. I was wondering if someone could point me in the right direction. Are there any functions to assist me with this or do i have to write my own function from scratch?

thanks, Robert.

Hi,
I think that you would find it easier to make your own function which sorts the array alphabetically.

My suggested sorting method is Bubble sort, since its short and easy.

I will experiment with it for a bit and let you know on whether it is successful or unsuccessful.

I hope you get it working

thanks... i'm experimenting with qsort now.

go to AI Horizon for all the different methods of sorting.
You never know when you might need it.

i'm having trouble getting qsort() working...

Code:

char* allsongs[MAXSONGS];

int compare( const void *arg1, const void *arg2 )
{
   /* Compare all of both strings: */
   return _stricmp( * ( char** ) arg1, * ( char** ) arg2 );
}

qsort((void*)allsongs, 10, sizeof(char*), compare);

this is my modification of the example given in the MSDN. but it gets an access voilation. (btw allsongs is sucessfully filled with about 300 strings)

if i do the following:

Code:

sprintf("%s\n", allsongs[10]);

it outputs a song fine. have i overlooked somthing?

Do yourself a favor and have a look at the bubble sorting method, or another one.

Just goto aihorizon.com and then click on Basic CS, there is a whole lot of algorithms for sorting.

thanks for all the help.. but i got qsort working. its seems fast enough for what i'm doing.

Its always a pleasure sharing some of my knowledge.
