Question

In C programming

Write a program that displays the appropriate prompt to input 5 scores. Once the user inputs the five integer values, your program calculates and prints the average. You do not need to declare five different variables, think of how you can get away with a single variable. The second part of this program will print A if the average of these 5 numbers is greater than or equal to 90 but less than 100, B if greater than or equal to 80 but less than 90 …. or F if the average is less than 60.

Answer 1

#include <stdio.h>

int main()
{
   char letter;
   int val = 0, i = 0, s = 0;
   double score;
   while(i<5){
      printf("Enter score: ");
      scanf("%d",&val);
      s += val;
      i++;
   }
   score = s/5.0;
   if(score < 60)
        letter = 'F';
    else if(score < 70)
        letter = 'D';
    else if(score < 80)
        letter = 'C';
    else if(score < 90)
        letter = 'B';
    else
        letter = 'A';
    printf("
Letter grade = %c
",letter);
    return 0;
}
