I'm experiencing a weird problem with my program and finally nail it down
to what exactly went wrong, so that I can write a minimum program to
duplicate it. See the following program:
package main
import (
"fmt"
)
type Vertex struct {
X int
Y int
}
func main() {
vs := []Vertex{
Vertex{1, 2}, // has type Vertex
Vertex{X: 3}, // Y:0 is implicit
Vertex{}, // X:0 and Y:0
}
fmt.Printf("Vertex Slice %+v\n", vs)
var vp *Vertex = nil
for _, v := range vs {
if v.X == 3 {
vp = &v
}
}
fmt.Printf("Found: %+v\n", vp)
}
https://play.golang.org/p/R645C5plojx
I was expecting that the found Vertex is "v.X == 3", however the result is
not.
- what exactly is causing the problem?
- how to fix it so that I got what I was looking for?
Again, the snip is at
https://play.golang.org/p/R645C5plojx
Thanks
