qsort() and strings/numbers
Hi all!
someone could help me to sort a string?
char strings[10000][100];
The strings have letters and numbers. Ex.:
256_test
test.435.433
Code:
/* qsort example */
#include <stdio.h>
#include <stdlib.h>
int values[] = { 40, 10, 100, 90, 20, 25 };
int compare (const void * a, const void * b)
{
return ( *(int*)a - *(int*)b );
}
int main ()
{
int * pItem;
int n;
qsort (values, 6, sizeof(int), compare);
for (n=0; n<6; n++)
{
printf ("%d ",values[n]);
}
return 0;
}
in this example (I found on google) I didn't understand the function compare. I think this one is just for numbers. What should I do to sort string and numbers?
Thank you in advance!
