Question

Need help on a simple c program. Writing a TestValue program. The program runs but doesn’t return a letter grade.
This is what I have so far.

#include <stdio.h>
int main()
{
        double testValue;
        char getGrade;
        printf("Enter your score between o and 100:");
        scanf("%if", &testValue);
        printf("Your grade is %c\n", getGrade);
        return 1;
}
char getGrade(double value)
{
  if(value>=90)
    return'A';
  else if(value>=80)
    return'B';
  else if(value>=70)
    return'C';
  else if(value>=60)
    return'D';
  else if(value>=50)
    return'F';
  return 1;
}

Answer 1

%if Should be %lf

You have not called the getGrade function

You have two identifiers with the same name.

Remove the char getGrade; declaration and just call the getGrade function.
