Recursive function help!

sh129951 (24)
Im stuck. Im having trouble making the linked list print all 'Z' if the elements in the list are capital. void make_Zs can only pass a parameter that is a pointer to the list.

make_Zs needs to be called inside its definition to "loop" through the list and change the capital letters to Zs

I keep getting invalid conversion from char to list_node?

This
void sub1_skip (list_ptr front);


and this
void sub1_skip (list_ptr stuff)


are different. I know your not at that point yet, but thought i should point that out.

In what way are they different Myangryplatypus?
