902. The level
of educational achievements
Determine the
level of educational achievements for the pupil (elementary, average, sufficient,
high) according to the given grade (from 1 to 12).
Input. One number that is a grade for the pupil.
Output. Print Initial for elementary level
(grade from 1 to 3), Average for
average level (grade from 4 t 6), Sufficient for sufficient level (grade from 7 to 9)
and High for high level (grade
from 10 to 12).

conditional statement
To solve the problem,
implement the conditional statement.
Algorithm realization
Read the grade of the
student. Print the answer by implementing the
conditional operator.
scanf("%d",&n);
if (n <= 3) printf("Initial\n"); else
if (n <= 6) printf("Average\n"); else
if (n <= 9) printf("Sufficient\n"); else
printf("High\n");
