    Names into Alphabetic Order

    Lo all
    I am wanting to sort a list of names into alphabetic order, however, I don't want to use a 2d array. I can get it to work using a 2d array and qsort, but how would I go about using an array of pointers to char and adjusting the pointers rather than copying the strings?

    If ne1 can give me ne tips to get me on the right lines it will be greatly appreciated.

    I would create a linked list of chars, then perform a bubble sort on the list.

    Have you done bubble sort try that with strings..

    #include <stdio.h>
    #include <stdlib.h>
    int main()
     char *ch[] = {"Welcome ","to ","C"};
     int cnt=0;
     while ( cnt < 3 ){
           printf("%s", ch[cnt] );
     }     cnt++;
          return 0;
    Implementation of cha *[] .....SO you can use bubble sort or qsort to sort them out remeber you dont compare strings with a == ...use your strcmp() function which resides in your string.h for comparison between 2 strings ..

    i think you best use a tree for something alphabetical. it's easiest and definitely fastest.
