**Introduction**

In this post, I am going to write a c program to count the number of even, odd and zero digits in a number. That means we will read a single number and then count how many even, odd and zeros are there. See the following expected output.

**Expected Output**

From the above expected output, we are reading a single number and counting the even number of digits, odd number of digits and number of zero’s. For this, you need to understand the logic of this program.

**Logic of this Program**

- Read any number from the console through the keyboard. Suppose that number is stored in the variable
**num.** - We need to separate each and every digit. So we will use the modulo operator to find the remainder.
- Find the remainder by dividing the number by 10 (
**Say rem=num%10**) - Now, check whether the value of that remainder is Zero or Even or Odd.
- Divide the same number by 10 to get the quotient (
**num=num/10**) - Now, repeat steps 3, 4 and 5 until the value of the variable
**num**is greater than zero.

I hope you have understood the above steps that we are performing. Now, see the following program.

**C Program to Count Even, Odd and Zero Digits in a Number**

```
#include <stdio.h>
#include <stdlib.h>
int main()
{
int num,rem,ne=0,no=0,nz=0,anum;
printf("Enter any Number\n");
scanf("%d",&num);
printf("In the given number %d\n",num);
while(num>0)
{
rem=num%10;
if(rem==0)
{
nz++;
}
else if(rem%2==0)
{
ne++;
}
else
{
no++;
}
num=num/10;
}
printf("EVEN number of digits except 0 are %d\n",ne);
printf("ODD number of digits are %d\n",no);
printf("number of ZERO digits are %d\n",nz);
return 0;
}
```

In the above c program, variables ne, no and nz are used to count the total number of even numbers, odd numbers and zeros respectively in the given number i.e. num.

I hope you have understood this program. If you have any difficulty to understand this program, please feel free to contact me.

Thank you.
