Thread: simple structure/linked list question

Code:

switch (input[0]) {
            case ('a'):
            case ('A'):
                add_to_list();
                break;
            case ('d'):
            case ('D'):
                delete_from_list();
                break;
            case ('p'):
            case ('P'):
                print_name();
                break;
            case ('l'):
            case ('L'):
                list_names();
                break;
            case ('q'):
            case ('Q'):
                free_list();
                return (0);
            default:
                printf ("Unknown command\n"); 
        }

You should look into tolower(), which is in <ctype.h>. It converts a character to lowercase. You could change the above code to

Code:

switch (tolower(input[0])) {
            case ('a'):
                add_to_list();
                break;
            case ('d'):
                delete_from_list();
                break;
            case ('p'):
                print_name();
                break;
            case ('l'):
                 list_names();
                break;
            case ('q'):
                 free_list();
                return (0);
            default:
                printf ("Unknown command\n"); 
        }
