Because I might have written some code in which I'm expecting that integer particular variable to have an integer value.
因为我可能写了一些代码,来把一些,变量的类型,指定为。
And unlike n, l can start all the way down at 0, and it increases by integer value, so we go 1, 2, 3, and all the way up.
不像n,l可以从0开始取,然后每次增加一个整数,所以我们可以去1,2,3,一直下去。
There's no decimal point; there's no point zero; there's no floating point value, it's just a hardcoded integer.
这里没有小数点,这里没有;,这里没有浮点数值,它只是一个整型数字。
