为什么Go编程中没有while循环？ 试图让用户输入数字1到12？ [关闭]

Question

package main
import (
    "fmt" 
)

func main() {
    var intN, intCounter int32
    var ulngFact int32

    for {
        fmt.Println("Enter a number (0 < N <= 12): ")//A do while loop
        fmt.Scanf("%d", &intN)                      // Until user enters
        if intN > 0 && intN < 12 {                  // a num 1 through 12
                break;
        }
    }
    ulngFact = 1
    for intCounter = 1; intCounter <= intN; intCounter++{
            ulngFact = ulngFact * intCounter
    }

    fmt.Printf("Required factorial is %d
", ulngFact)
    fmt.Printf("Thank you.
") }

Here is your "while" loop. Go simply doesn't have a while loop because it's for loop already covers that.

for !(intN > 0 && intN <= 12) {
    fmt.Println("Enter a number (0 < N <= 12): ")
    fmt.Scanf("%d", &intN)
}

Not sure if you wanted the 12 included or not (the print statement suggests it should be included, so I did include it).

Hope this helps.
