## How to find odd and even numbers in C#

### There are 2 methods find even or odd numbers in C#.

### Method 1: Modulus operator %

### Method 2: BitField Operator &

### Method 1: Modulus Operator %

Note:Find even or odd with modulus operator,When divided by 2 if remainder of the number is 0, then number is even otherwise odd.

for number 3 remainder is 1 so odd 3%2=1

for number 4 remainder is 0 so even. 4 %2=0

public bool isEven(int num)

{

if (num % 2 == 0) return true;

else return false;

}

{

if (num % 2 == 0) return true;

else return false;

}

### Method 2: BitField Operator &

public bool isEvenUsingBitFields(Int32 num)

{

if ((num & 1) ==0) return true;

else return false;

}
