Using a pointer to array

Question

I\'m having a little play with google\'s Go language, and I\'ve run into something which is fairly basic in C but doesn\'t seem to be covered in the documentation I\'ve seen

Answer 1

Here's a working Go program.

package main

import "fmt"

func conv(x, h []int) []int {
    y := make([]int, len(x)+len(h)-1)
    for i := 0; i < len(x); i++ {
        for j := 0; j < len(h); j++ {
            y[i+j] += x[i] * h[j]
        }
    }
    return y
}

func main() {
    x := []int{1, 2}
    h := []int{7, 8, 9}
    y := conv(x, h)
    fmt.Println(len(y), y)
}

To avoid wrong guesses, read the Go documentation: The Go Programming Language.
