Alternating row colors Alternating row colors

What is alternating row colors?
- Alternating row colours is when every second value is a different color.

Code: This is our main code, this checks what $i is equal to and if it is 0 the background is black and if it is not then it is white.

- black
- white
- black
- white
and so on..

Now for the second part we need to increse and decrease the value of $i so it will loop through the background colors.

Code: Now all we have added is $i and $i-- we need to do this otherwise it wouldent loop properly. $i-- will set $i to 0 and $i will set $i to 1.
