Go 程序打印奇数

此 Go 程序中从 1 到 n 打印奇数的 for 循环从一开始，在 oddnum 处停止。在循环内部，if 条件 (x % 2 != 0) 检查数字除以二的余数是否不等于零。如果为真，则打印该奇数。

package main

import "fmt"

func main() {

    var odnum int

    fmt.Print("Enter the Number to Print Odd's = ")
    fmt.Scanln(&odnum)

    for x := 1; x <= odnum; x++ {
        if x%2 != 0 {
            fmt.Print(x, "\t")
        }
    }
}

Enter the Number to Print Odd's = 10
1       3       5       7       9 

Golang 程序打印从 1 到 N 的奇数

在此 Golang 程序中，for 循环从一开始，每次增加二 (x = x + 2)。这表明所有数字都将是奇数，无需添加额外的 if 条件来检查余数。

package main

import "fmt"

func main() {

    var odnum int

    fmt.Print("Enter the Number to Print Odd's = ")
    fmt.Scanln(&odnum)

    for x := 1; x <= odnum; x = x + 2 {
        fmt.Print(x, "\t")
    }
}

Enter the Number to Print Odd's = 20
1       3       5       7       9       11      13      15      17      19

此 Go 程序显示从最小值到最大值的奇数。第一个 if 语句 (Oddmin % 2 == 0) 检查最小值是否为偶数，如果为真，则最小值增加一 (oddmin++) 以变为奇数。在 for 循环中，我们将 odd 值增加了二，以便所有数字都是奇数。

package main

import "fmt"

func main() {

    var oddmin, oddmax int

    fmt.Print("Enter the Minimum to Start Printing Odd's = ")
    fmt.Scanln(&oddmin)
    fmt.Print("Enter the Maximum to End Printing Odd's = ")
    fmt.Scanln(&oddmax)

    if oddmin%2 == 0 {
        oddmin++
    }
    fmt.Print("The Odd Numbers from ", oddmin, " to ", oddmax, " are \n")
    for i := oddmin; i <= oddmax; i = i + 2 {
        fmt.Print(i, "\t")
    }
}

Enter the Minimum to Start Printing Odd's = 10
Enter the Maximum to End Printing Odd's = 30
The Odd Numbers from 11 to 30 are 
11      13      15      17      19      21      23      25      27      29

这个 Golang 奇数 示例 与第一个示例相同。但是，它打印从最小值开始并在最大限制处结束的奇数。

package main

import "fmt"

func main() {

    var oddmin, oddmax int

    fmt.Print("Enter the Minimum to Start Printing Odd's = ")
    fmt.Scanln(&oddmin)
    fmt.Print("Enter the Maximum to End Printing Odd's = ")
    fmt.Scanln(&oddmax)

    fmt.Print("The Odd Numbers from ", oddmin, " to ", oddmax, " are \n")
    for i := oddmin; i <= oddmax; i++ {
        if i%2 != 0 {
            fmt.Print(i, "\t")
        }
    }
}
