C programming question

Question

The function named findNote, which returns a student's letter grade according to the data(score out of 100, class average, standard deviation) sent to it.

Answer 1

Here is a function to do what you're saying. You didn't say what percentage range applies to each letter so I assumed some.

char findNote(int data)
{
if (data >= 80)
return 'A';
else if (data >= 70)
return 'B';
else if (data >= 60)
return 'C';
else if (data >= 50)
return 'D';
else
return 'F';
}
