#include 
#include 
using namespace std;

struct grades
{
int grade1;
int grade2;
int grade3;
int grade4;
} mygradesi,mygradeso;

int main ()
{
int answer;
do
{
coutanswer;
if (answer==2)
{
struct grades * mygradesptri;
mygradesptri=&mygradesi;
ifstream myfilei;
myfilei.open ("binary.bin", ios::in|ios::binary);
if (myfilei.is_open())
{
read(mygradesptri, sizeof(grades));
cout
