在Go中声明并未使用的变量

Question

In the following code:

func PrimeF(n uint64) {
var i,t uint64 = 2,3


for ; i < n; {
    if n%i == 0 {
        n /= i
    }

   }
}

Why do I get the error message: "t declared and not used"?

Answer 1

Because you declared a variable called t here:

var i,t uint64 = 2,3

but never used that variable.
