Pointers: Warning C4028

Good morning!
Though my l'il program seems to be working just fine, I get this warning when compiling from the command line:

"Warning C4028:formal parameter 1 different from declaration"
Header file:

Code:

#ifndef GRADES_H
#define GRADES_H

	float calcAssignment (void);
	float calcExam (void);
	float calcTotal (float, float);
	void  displayInfo (char* name);
	void studentName(char* name);
	void grades (void);

	typedef struct {

	char name[50];
	int assignment[100];
	int exam[100];

} StudentGrades;

StudentGrades student = {0};

#endif

Source:

Code:

void grades (void)

{
	
	char firstlast[BUFSIZ] = {0};

	DEBUG_PRINT("Entering grades function ");

    studentName(firstlast); 
	displayInfo(firstlast);


}

void studentName(StudentGrades *student)//<<<-------- warning!!
{

	DEBUG_PRINT("Entering studentName function ");

	printf	("\n\nPlease enter student's name:");	
	scanf	( "%[^'\n']", student ->name );

}


void displayInfo (StudentGrades *student)// <<<------------  warning!!
...

(shortened for brevity...)
What is causing this? Do I need more coffee? Golly it's late!

In the header file they're defined as using char* parameters, yet in the implementation they're defined as using the type StudentGrades.


Switch one or the other and it'll work.

Code:

void studentName(char* name);

Code:

void studentName(StudentGrades *student)

Notice the difference in the function declarations? Well your compiler notices the difference too, and it doesn't like it.

Wonderful - thank you so much, I wasn't even looking at the friggin' header...
