如何在Go中将数字列表读入数组

Question

I want to read a list of numbers given by the user into an array and perform operations on them.

package main
import "fmt"

func main() {
    var n,c,i int
    var a []int    
fmt.Println("Enter the number of inputs")
 fmt.Scanln(&n)
fmt.Println("Enter the inputs")
 for i=0 ; i<n-1; i++ {
     fmt.Scanln(&c)
}
    fmt.Println(a[i]) 
}

Can someone help me out.

What you are using is slices not arrays. Arrays can only be used when you know the length at compile time.

package main

import "fmt"

func main() {
    length := 0
    fmt.Println("Enter the number of inputs")
    fmt.Scanln(&length)
    fmt.Println("Enter the inputs")
    numbers := make([]int, length)
    for i := 0; i < length; i++ {
        fmt.Scanln(&numbers[i])
    }
    fmt.Println(numbers)
}
