How to create resizable arrays in Go

Question

I come from a C++ background and I'm used to using the std::vector class for things like this. Lets assume I want a dynamic array of these:
type a struct {
    b int
    c string
}

What is the standard way of doing this

Use the append() builtin Example: package main import "fmt" type mytype struct { a, b int } func main() { a := []mytype{mytype{1, 2}, mytype{3, 4}} a = append(a, mytype{5, 6}) fmt.Println(a) } https://play.golang.org/p/OmI87N3nrq4 In-depth reading: blog.golang.org/go-slices-usage-and-internals
