3.3 Write a program to prompt for a score between 0.0 and 1.0. If the score is out of range, print an error. If the score is between 0.0 and 1.0, print a grade using the following table:
Score Grade
>= 0.9 A
>= 0.8 B
>= 0.7 C
>= 0.6 D
< 0.6 F
If the user enters a value out of range, print a suitable error message and exit. For the test, enter a score of 0.85.

#include<iostream.h>
#include<conio.h>
void main( )
{
clrscr( );
float score;
cout<<"enter score";
cin>>score; // score =0.85 (as test)
if(score>=0.9&&score<=1.0)
{
cout<<"A";
}
else if ( score<=0.9&&score>0.8)
{
cout<<"B"
}
else if(score <=0.8&& score>0.7)
{
cout<<"C";
}
else if(score<=0.7&&score>=0.6)
{
cout<<"D";
}
else if(score<0.6)
{
cout<<"F"
}
else
{
cout<<"error occurred";
}
getch( );
}
