Question

3. Write a program using switch-case statements that accepts an integer number between 0 and 100 and, based on its value, reports its equivalent letter grade (A, B, C, D, or F).

Answer 1

Since the Language to be coded was not mentioned, I have written it in C

#include<stdio.h>
 int main()
 {
     int marks;

     printf("Enter marks between 0 and 100: ");  //Asks for mark input
     scanf("%d",&marks);   //Stores in variable

     switch( score / 10 ) //Runs a switch case to check the grade
     {

     case 10:
     case 9:
         printf("Grade is : A\n"); //Prints the Grade in each case
         break;

     case 8:
         printf("Grade is: B\n");
         break;

     case 7:
         printf("Grade is: C\n");
         break;

     case 6:
         printf("Grade is: D\n");
         break;

     case 5:
         printf("Grade is: E\n");
         break;

     default:
         printf("Grade is: F\n");
         break;

     }
