Q2.Write a program to accept a number and count number of even, odd and zero digits within that number. [25 Marks]
#include <stdio.h>

int num, digit, even = 0, odd = 0, zero = 0;
printf("Enter a number: ");
scanf("%d", &num);
while (num > 0) {
digit = num % 10;
if (digit == 0)
zero++;
else if (digit % 2 == 0)
even++;
else
odd++;
num /= 10;
}
printf("Even digits: %d\n", even);
printf("Odd digits: %d\n", odd);
printf("Zero digits: %d\n", zero);
return 0;
