#include <stdio.h>

int main() {
  int age;
  int cnt_baby = 0, cnt_school = 0, cnt_adult = 0;
  int count = 0;

  while (count < 15) {
    printf("Enter age of person [%d]: ", count + 1);
    scanf("%d", & age);

    if (age >= 0 && age <= 5)
      cnt_baby++;
    else if (age >= 6 && age <= 17)
      cnt_school++;
    else
      cnt_adult++;

    //increase counter
    count++;
  }

  printf("Baby age: %d\n", cnt_baby);
  printf("School age: %d\n", cnt_school);
  printf("Adult age: %d\n", cnt_adult);

  return 0;
