Odd or Even

A number which is divisible by 2 is known as even number.

If it’s not divisible by 2, it will be considered as odd numbers.



Divisible by N

In general, a number is divisible by N, if and only if the number % N becomes zero.

In other words, if we divide that number by N, the remainder should be zero.

Number = Divisor * Quotient + Remainder.

Any number can be expressed using this format,

Number = Q * D + R

10 is divisible by 5.

Because,

10 = (2*5) + 0

Here Remainder is zero. So, 10 is divisible by 5.



Analysis

Let’s take first 10 numbers and perform modulo 2 operation.

Pictorial Explanation

Odd or Even

If we observe the about results, we can notice that odd numbers are yielding remainder 1 while performing mod 2 operation.

And even numbers are resulting 0 while performing mod 2 operation.

Let’s a write code for this logic.



Procedure

Get input from user.

If num % 2 is zero, Print even

else, print odd



Example

Case 1

Input

10

Output

Even

Case 2

Input

13

Output

Odd

Case 3

Input

125

Output

Odd



Program

Example

#include<stdio.h>

int main()
{
    int num;
 
    scanf("%d",&num);
 
    if(num % 2 == 0)
        printf("Even");
    else
        printf("Odd");
     
    return 0;
}
