package main

import (
	"fmt"
)

// SIZE 定义数组大小
const SIZE = 5

func main() {
	arr1 := [SIZE]int{11, 23, 45, 66, 89}
	arr2 := [SIZE + 1]int{}
	num := 0

	fmt.Println("arr1 = ", arr1)
	fmt.Println("请输入一个待插入的整数")
	fmt.Scanf("%d", #)
	count := 0
	for i := 0; i < SIZE; i++ {

		if arr1[i] < num {
			arr2[i] = arr1[i]
		} else if arr1[i] >= num {
			arr2[i] = num
			for j := i; j < SIZE; j++ {
				arr2[j+1] = arr1[j]
				count++
			}
			count++
			break
		}
		count++

	}
	if count == SIZE {
		arr2[SIZE] = num
	}

	fmt.Println("arr2 = ", arr2)
}  

运行效果如下：
