Given a struct definition like this:

struct Student { string name; int studentID; float gpa; }; 

...identify the "host object" in the following code block in the main program:

Student x; output(x); // where "output" is a function with a prototype and definition 

1

Student

2	trick question -- there is no host object

3

x

4	output's return value

5

output

Write a C++ statement to return a reference to the host object from a member setter function.
