Question

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

C language

#include<stdio.h>

int main()

{

int i;

printf("enter the score");

scanf("%d",&i);

if( i>=0.9 && i<=1)

printf("A");

else if( i>=0.8)

printf("B");

else if( i>=0.7)

printf("c");

else if( i>=0.6)

printf("D");

else if( i <0.6)

printf ("F");

else

printf("invalid");

return 0;

}
