Answer 1

#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
int ID;
double First, Second, Final, Total;
char Grade;
cout<<"Enter ID : ";
cin>>ID;
cout<<"Enter First mark : ";
cin>>First;
cout<<"Enter Second mark : ";
cin>>Second;
cout<<"Enter Final mark : ";
cin>>Final;
Total = First + Second + Final;
if (Total>=90 && Total <=100) Grade = 'A'; else if(Total >= 80 && Total < 90) Grade = 'B';
else if(Total >= 70 && Total < 80) Grade = 'C';
else if(Total >= 60 && Total < 70) Grade = 'D';
else Grade = 'F';
if(Total > 100)
{
