The syntax of the typedef is wrong. try: ... typedef struct { ... //attributes ... } <struct_name_here>; i changed yours to define a type called student, then made two student variables: s1 & s2 EDIT: then deleted the second variable because it was unused Also, look at your string formatting. You are looking for %c 'characters' but passing %s 'strings' https://code.sololearn.com/cu5kZ6gQdpJ0/?ref=app
