• It may not be necessary to keep the break point in the above part of the program. So we will see the code around line 15.

(gdb)   list   15

10.       }

12.        length = strlen(argv[1]);
13.        mid = length/2;
14.        for (i=0; i<=mid; ++i){
15.              if (argv[1][i] != argv[1][lengthi]){
16.              printf("\"%s\" is not a palindrome.\n", argv[1]);
17.                       exit(0);
18.                       }
19. }
