Given the following definition of a StudentRecord and #define's:

typedef struct {
	char 		name[MAX_NAME_LEN];
	int		stID;
	double		cse142Grade;
} StudentRecord;

#define	LESS		-1
#define	EQUAL		0
#define	GREATER		1

Write a function which:

• Swaps two StudentRecord's (implement this using pointers)
• Compares two StudentRecord's and returns if the first StudentRecord's is "less", "equal", or "greater" than the second. How do you determine that one StudentRecord is "greater" than another? You decide, but make sure you comment your assumption in the function comment! (for an extra challenge, implement this using pointers).
