How to implement 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:

typ         


        

Answer 1

Hi we can simply do this in two ways

type mytype struct {
  a, b int
}

Just do like this

1. Without append

__

a := []mytype{mytype{1, 2}, mytype{3, 4}, mytype{4, 5}}

2. With append

__

a:=  append([]mytype{}, mytype{1, 2}, mytype{3, 4}, mytype{4, 5})

Add as much as you want. First one is an easy way to do this. Hope this will help you.
