Counting A and B Students Based on Grades

This C program prompts the user to enter grades for 10 students and counts how many received A (above 85) and B (above 75) grades. It ensures that the grades entered are between 0 and 100, requesting re-entry for invalid inputs. At the end, it displays the number of A and B students.

#include <stdio.h>

int main() {
	
	int i;
	int grade;
	int a_students = 0;
	int b_students = 0;
	
	for (i = 0; i < 10; i++) {
		printf("Please enter student %d grade: ", i+1);
		scanf("%d", &grade);
		
		if (grade <= 100 && grade >= 0) {
			if (grade > 85) {
				a_students++;
			}
			else {
				if (grade > 75) {
					b_students++;
				}
			}
		}
		else {
			printf(">> Please enter grade from 0 to 100\n");
			i--;
		}
	}
	
	printf("A students = %d | B students = %d\n", a_students, b_students);
	
	return 0;
}
