if (i%3) 的意思是，把i%3当做一个变量，这个变量只有真假两个值，0为假，非0为真。 所以如果i%3不等于零，即i不能整除3时，条件成立，执行下面语句。

In the complex plane, which is a special interpretation of a Cartesian plane, i is the point located one unit from the origin along the imaginary axis (which is perpendicular to the real axis).

Imaginary numbers are numbers that result in a negative number when squared. They are also defined as the square root of negative numbers. An imaginary number is the product of a non-zero real number and the imaginary unit "i" (which is also known as "iota"), where i = √ (-1) (or) i 2 = -1. Let's try squaring some real numbers: (−2) 2 = −2×−2 = 4.

“++”是编程语言中的自增运算符，其作用是将变量中的数值在每经过该语句后自动执行加一运算，++i和i++是有区别的，区别在于++i是先将i变量中的数值进行加一运算，然后再执行下面的语句，而i++是先执行下面的语句，即i还是以原来的值加入运算，然后再自加一。 i++和++i怎么算啊？ 设i=3,当i=3时,i++就是在循环中执行语句时i中的变量值还是3，在下一次循环时再次经过i++语句后，此时执行语句时i的取值才是4，++i是经过该语句后，一次循环中的下面的语句都执行i=4,等 …
