Question

Write a program that asks the user for their grade (integers only from 0-100). Depending on the grade number, assign a letter grade. Le. 0.50: F, 51.65: D, 6675: C, 76-85: B, 86-100: A. Use nested conditionals here. (Be sure to convert the string! Bonus: how would you handle cases where the user enters-1 or 101?)

#include <stdio.h>

int main()
{
   char letter;
   int score = 0;
   do{
      if(!(score>=0 && score<=100)){
         printf("Invalid input\n");
      }
      printf("Enter score: ");
      scanf("%d",&score);
   }while(!(score>=0 && score<=100));
   if(score < 50)
        letter = 'F';
    else if(score < 65)
        letter = 'D';
    else if(score < 75)
        letter = 'C';
    else if(score < 85)
        letter = 'B';
    else
        letter = 'A';
    printf("\nLetter grade = %c\n",letter);
    return 0;
}
