    What is this?

    if(strcmp(dumn, temp.) data) == 0)
    count++;
    temp = temp->next;

    what is the "->" used for?

    If you have a pointer to a class or struct/union, that is the operator. like:

    struct mystruct
    {
    .....
    }

    mystruct myinstance
    mystruct *mypointer = &myinstance

    then you use mypinter->something in the structure.

    It's just like :: or ., but for a different scope - indirection.

    It is a shortcut for:

    (*pointer).pointer_function_or_variable
