here's my running program, but my instructor want it to be sorted alphabetically... so someone help me with this...
its 2 dimensional array of strings but not yet sorted...
pls give me some function how to sort it by alphabetical order...

can you use the sort library funtion, e.g.
http://www.cplusplus.com/reference/clibrary/cstdlib/qsort.html

or do you have to write you own?

you can use function strcmp() to compare a pair of strings

#include<string.h>
main (void){
    char name[20][20];
    int i,x;    
    char hold;
    clrscr();
        for(i=0;i<=4;i++){
        printf("Enter the Names:\n",i);
        scanf("%s",&name[i]);
        }
 
        //sorting//
 
 
        for(i=0;i<=4;i++){
          for(x=i;x<=4;x++){
            name[i]="abc";
            hold[x]="afs";
            if(name[i]>hold[x]){
             printf("%s\n",name[i]);
            else
            printf("%s\n",hold[x]);
            }
            }
         }
       for(i=0;i<=4;i++){
        printf("%s\n",name[i]);
        }
    getch();
    return 0;
}

anybody can sort by this by alphabetical order??
to sort pls start at the statement //sorting//

No one is going to write your code for you. Horace gave you the tool that you need to compare two strings, why don't you try to use it to compare a few strings and see if you can determine how you might be able to tell which one comes before the other in alphabetical order.

You should also state what you ment by sorting a 2D array as this could mean a few different things. Also describe any restrictions and post your solution (working or not) so that we can see that you are trying.

thats it, i don't know how to do it the sorting part, thats y i need your help...

I assume you are sorting the 2D char array (char name[20][20]) as above.

Then I would assume this means that as you increase the first index (name[0], name[1], ... , name[19]), the strings stored in the second index (name[0][0] through name[0][19]) should be getting lexicographically larger, or alphabetically larger. If you have "Animal" and "Baseball", then "Baseball" is lexicographically larger - thus, "Baseball"s index will be greater than "Animal"s.
