Question

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.

Answer 1

Explanation:

score = float(raw_input("Enter score between 0.0 and 1.0: "))

if score>1.0 or score<0.0 :

print "error"

elif score>=0.9 :

print 'A'

elif score>=0.8 :

print 'B'

elif score>=0.7 :

print 'C'

elif score>=0.6 :

print 'D'

else :

print 'F'

Answer 2

#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( );

}

output:- (for 0.85)

B
