lesson 6 pass by pointers

problem 1 on the worksheet-- when passing by pointers, the variables remain in scope so to speak so their values are changed

A struct is sorta like an object in python or something but not really it's basically just a bucket of crap
see lsn6.c

pass pointers to structs-- printf("Name: %s\n", (*stu).name);

alternatively use the arrow-- printf("Name: %s\n", stu->name);
