Grade Evaluator

Hi, I dont really know how to write the function to compute the final score, which is equal to 0.75(quiz1+quiz2+quiz3)+0.25(exam1+exam2+exam3).

Code:

#include<stdio.h>

#define NAME 25
#define SOCIAL 12
#define PHONE 15
#define QUIZ 13
#define EXAM 13
#define FINAL 3
#define SIZE 2

struct {
	char first[NAME];
	char last[NAME];
}typedef Name;

struct {
	int first3;
	int middle2;
	int last4;
}typedef Social;

struct {
	int code;
	int first3;
	int last4;
}typedef Phone;

struct {
	int quiz1[QUIZ];
	int quiz2[QUIZ];
	int quiz3[QUIZ];
}typedef Quiz;

struct {
	int exam1;
	int exam2;
	int exam3;
}typedef Exam;

struct {
	Name name;
	Social social;
	Phone phone;
	Quiz quiz;
	Exam exam;
} typedef Grade;

void enterGrade(Grade *cptr);

int Final(int quiz int exam);

int main()
{
	Grade grade[SIZE];
	int x;
	
	for(x=0;x<SIZE;x++);
		enterGrade(&grade);

	return 0;
}

void enterGrade(Grade *cptr)
{
	
	printf("Enter first name: ");
	gets(cptr->name.first);
	printf("Enter last name: ");
	gets(cptr->name.last);
	printf("Enter social sercurity number: ");
	scanf("%s", &cptr->social.first3, &cptr->social.middle2,
		  &cptr->social.last4);
	printf("Enter phone number: ");
	scanf("%s", &cptr->phone.code,&cptr->phone.first3,&cptr->phone.last4);
	printf("Enter 1st quiz score: ");
	scanf("%d", &cptr->quiz.quiz1);
	printf("Enter 2nd quiz score: ");
	scanf("%d", &cptr->quiz.quiz2);
	printf("Enter 3rd quiz score: ");
	scanf("%d", &cptr->quiz.quiz3);
	printf("Enter 1st exam score: ");
	scanf("%d", &cptr->exam.exam1);
	printf("Enter 2nd exam score: ");
	scanf("%d", &cptr->exam.exam2);
	printf("Enter 3rd exam score: ");
	scanf("%d", &cptr->exam.exam3);


}

int Final (int quiz int exam)
{
	Final = 0.75(&cptr->quiz.quiz1+&cptr->quiz.quiz2+&cptr->quiz.quiz3)+
			0.25(&cptr->exam.exam1+&cptr->exam.exam2+&cptr->exam.exam3);
	return x;
}

Code:

#include<stdio.h>

#define NAME 25
#define SOCIAL 12
#define PHONE 15
#define QUIZ 13
#define EXAM 13
#define FINAL 3
#define SIZE 2

struct {
	char first[NAME];
	char last[NAME];
}typedef Name;

struct {
	int first3;
	int middle2;
	int last4;
}typedef Social;

struct {
	int code;
	int first3;
	int last4;
}typedef Phone;

struct {
	int quiz1[QUIZ];
	int quiz2[QUIZ];
	int quiz3[QUIZ];
}typedef Quiz;

struct {
	int exam1;
	int exam2;
	int exam3;
}typedef Exam;

struct {
	Name name;
	Social social;
	Phone phone;
	Quiz quiz;
	Exam exam;
} typedef Grade;

void enterGrade(Grade *cptr);

int Final();

int main()
{
	Grade grade[SIZE];
	int x;
	
	for(x=0;x<SIZE;x++);
		enterGrade(&grade[x]);

	return 0;
}

void enterGrade(Grade *cptr)
{
	fflush(stdin);
	printf("Enter first name: ");
	gets(cptr->name.first);
	printf("Enter last name: ");
	gets(cptr->name.last);
	fflush(stdin);
	printf("Enter social sercurity number: ");
	scanf("%s", &cptr->social.first3, &cptr->social.middle2,
		  &cptr->social.last4);
	printf("Enter phone number: ");
	scanf("%s", &cptr->phone.code,&cptr->phone.first3,&cptr->phone.last4);
	printf("Enter 1st quiz score: ");
	scanf("%d", &cptr->quiz.quiz1);
	printf("Enter 2nd quiz score: ");
	scanf("%d", &cptr->quiz.quiz2);
	printf("Enter 3rd quiz score: ");
	scanf("%d", &cptr->quiz.quiz3);
	printf("Enter 1st exam score: ");
	scanf("%d", &cptr->exam.exam1);
	printf("Enter 2nd exam score: ");
	scanf("%d", &cptr->exam.exam2);
	printf("Enter 3rd exam score: ");
	scanf("%d", &cptr->exam.exam3);


}

int Final ()
{
	int quiz1,quiz2,quiz3,exam1,exam2,exam3,Final;

	Final = 0.75(quiz1+quiz2+quiz3)+ 0.25(exam1+exam2+exam3);
	
	return Final;
}

i got 2 errors thats the same and it saids

error 2064:term does not evaluate to a function taking 26447744.

can someone please help me and tell me what that means

I think you're supposed to put typedef before struct.

Did the error give a line number or anything?

Oh yeah, and don't use gets().

Final = 0.75(quiz1+quiz2+quiz3)+ 0.25(exam1+exam2+exam3);

This is invalid in C. Try this:

Code:

Final = 0.75*(quiz1+quiz2+quiz3)+ 0.25*(exam1+exam2+exam3);

I don't think you ever call Final(). (Was this intentional?)

Another thing I just noticed is that you have a variable called Final in the function Final(). I don't think this will work.

When you access a member of a pointer to a struct, you don't use an ampersand (&):

Code:

int x;
struct {
    int i;
} s, *p;

p = &s;
x = s.i;
x = p->i;

Well, one problem is that your quiz1, quiz2, and quiz3 data members are declared as arrays when it seems (?)they should not be. Haven't looked beyond that, this just jumped out at me.

Code:

#define QUIZ 13

struct {
    int quiz1[QUIZ];
    int quiz2[QUIZ];
    int quiz3[QUIZ];
}typedef Quiz;

struct {
    Name name;
    Social social;
    Phone phone;
    Quiz quiz;
    Exam exam;
} typedef Grade;

...

printf("Enter 1st quiz score: ");
scanf("%d", &cptr->quiz.quiz1);
printf("Enter 2nd quiz score: ");
scanf("%d", &cptr->quiz.quiz2);
printf("Enter 3rd quiz score: ");
scanf("%d", &cptr->quiz.quiz3);
