#include <stdio.h>
int main () 
{
int id;
float gpa;
int flag; // 1=A+,2=A,3=B+,4=B,5=C+,6=C,7=D+,8=D
printf("Please Enter your ID : ");
scanf("%d",&id);
printf("Please Enter your GPA : ");
scanf("%f",&gpa);
if ( gpa > 5 && gpa < 0 ) printf("Error, the GPA is False.");
else 
{
if (gpa >= 4.5) flag = 1;
else if (gpa >= 4) flag = 2;
else if (gpa >= 3.5) flag = 3;
else if (gpa >= 3) flag = 4;
else if (gpa >= 2.5) flag = 5;
else if (gpa >= 2) flag = 6;
else if (gpa >= 1.5) flag = 7;
else if (gpa >= 1) flag = 8;
printf("\nYour ID : %d\n",id);
switch (flag) 
{
case 1 :
printf("Your GPA is A+ .");
break;
case 2 :
printf("Your GPA is A .");
break;
case 3 :
