#include <iostream>
#include <conio.h>
#include <cmath>
using namespace std;
int main()
{
char 'A''B','C','D','E','F';
int numbers;
cout<<"Enter numbers"<<endl;
cin>>numbers;
if (numbers==90)
{cout<<"Grade is A"}
else if(numbers==80)
{cout<<"Grade is B"<<endl;}
else if (numbers==70)
{cout<<"Grade is C"<<endl;}
else if (numbers==60)
{cout<<"Grade is D"<<endl;}
