You would need to be way more specific than "something is wrong". Why are you creating a variable, multiple, and not using it? Why are you checking num 100 times? Do you really think that a single number is going to change whether it's odd or even if you check it enough times?

Solution 2

to check a num is even or not use this simple code :

static bool EvenNumber (int num)
{
if(num%2==0)
return true
else
return false
}

Thank you all.

Solution 3

You can use single line to check int value for even or odd

C#

public static bool IsEven(int num)
{
    return num%2 == 0;
}

public static bool IsOdd(int num)
{
    return num%2 != 0;
}

Do you understand the code? where did you get the code from?
Why is there a multiple that was never used and what is the use of the for loop?
Try this example:

C#

static bool EvenNumber (int num)
{
    bool isEven = true;

    if (Math.Abs(num % 2) == 1)
        isEven= false;

    return isEven;
}
