On every third iteration C# [duplicate]

Answer 1

This problem can be solved with the modulo (or division remainder) operator as follows.

if (0 == waveCounter % 3)
{
    // do stuff
}
else
{
    // do other stuff
}

Answer 2

if((waveCounter % 3) == 0)

Modulo arithmetic: it divides a number by 3 and checks for the remainder. A number that is divisable by 3 has no remainder (and thus ==0)

Answer 3

Use the modulus operator, which, in simple terms, gets the remainder after division. https://msdn.microsoft.com/en-us/library/0w4e0fzs.aspx

If the remainder is 0, then you know the number is divisible by 3:

if(waveCounter % 3 == 0)
{ 
    //do something
}
