# Identify whether the number is Even or Odd in C-language

If any number is exactly divisible by 2 then it’s an even number else it’s an odd number.

In this tutorial we’ll see how to check whether the provided number is even or odd number using Modulo(`%`

).

### Flowchart

#### Note

- The
**remainder**calculated with`%`

(Modulo) on dividing by**2**, will always be`0`

for all**even**numbers. - Whereas the
**remainder**on dividing by**2**, will always be`1`

for all**odd**numbers.

### Code

```
int main()
{
int a = 256;
int rem = a % 2;
printf("\nA: %d", a);
printf("\nRemainder: %d", rem);
if(rem == 0)
{
printf("\n%d is an even number", a);
}
else
{
printf("\n%d is an odd number", a);
}
/*
Divided by 2
12 -> 0
13 -> 1
14 -> 0
15 -> 1
16 -> 0
17 -> 1
18 -> 0
19 -> 1
20 -> 0
21 -> 1
22 -> 0
*/
printf("\n");
return 0;
}
```

### Output

```
256 is an even number
```

Happy 😄 coding
