The deleteFirst function, as the name suggests, deletes the first element of the list. To do this, simply point the listHead to the second element in the list! You may need to handle the special case of listHead pointing to NULL (i.e. an empty list) If done correctly, your output should look like this: inserting first element with data 2000 inserting element with data 2018 printing list: 2000 2018 inserting element with data 2001 inserting element with data 1998 inserting element with data 0 inserting element with data 1999 inserting element with data 2021 inserting element with data 2020 printing list: 2000 2018 2001 1998 0 1999 2021 2020 deleting first element from list: printing list: 2018 2001 1998 0 1999 2021 2020
