How to generate numbers sequentially in go language

Go language implements the method of sequentially generating numbers: first create a go code sample file; then customize a makeRange method; and finally use the "for i := range a {a[i] = min i}" method Just generate numbers sequentially.

There is no range equivalent to PHP in the Go standard library (this PHP function can return a range containing an array of elements between low and high).

We have to create one ourselves.

The easiest is to use a for loop:

func makeRange(min, max int) []int { a := make([]int, max-min+1) for i := range a { a[i] = min + i } return a }

Use this:

a := makeRange(10, 20) fmt.Println(a)

Output (try it on Go Playground):

[10 11 12 13 14 15 16 17 18 19 20]

Also note , if the range is small, you can use compound literals:

a := []int{1, 2, 3} fmt.Println(a) // Output is [1 2 3]
