我正在尝试通过实现一个随机图来学习 go。我在 n.value undefined(int 类型没有字段或方法值)和 n.neigbours undefined(int 类型没有字段或方法 neigbours)上收到错误。我无法理解编译错误,因为我在 g.nodes = make([]node, g.nodesnr) 中创建了一个新的 nodenr 大小的空节点切片。问题是什么?
package main
import (
"fmt"
//"math/rand"
)
type node struct {
value int
neigbours []int
}
type edge struct {
source int
sink int
}
type graph struct {
nodesnr, edgesnr int
nodes []node
edges chan edge
}
func main() {
randomGraph()
}
func input(tname string) (number int) {
fmt.Println("input a number of " + tname)
fmt.Scan(&number)
return
}
func randomGraph() (g graph) {
g = graph{nodesnr: input("nodes"), edgesnr: input("edges")}
g.addNodes()
for i := 0; i < g.nodesnr; i++ {
fmt.Println(g.nodes[i].value)
}
//g.addEdges()
return
}
func (g *graph) addNodes() {
g.nodes = make([]node, g.nodesnr)
for n := range g.nodes {
n.value = 2
n.neigbours = nil
return
}
}
func (g *graph) addEdges() {
g.edges = make(chan edge)
for i := 0; i < g.edgesnr; i++ {
//g.newEdge()
return
}
}
/*
func (g* graph) newEdge(){
e := new(edge)
e.source, e.sink = rand.Intn(g.nodesnr), rand.Intn(g.nodesnr)
g.edges <-e*
//g.addEdge()
}
*/
func (g *graph) edgeCheck(ep *edge) string {
if ep.source == ep.sink {
return "self"
}
//if(g.neigbourCheck(g.nodes[ep.source].neigbours, ep.sink) OR g.neigbourCheck(g.nodes[ep.sink].neigbours, ep.source){
// return "present"
return "empty"
}
func (g *graph) neigbourCheck(neigbours []node, node int) bool {
for neigbour := range neigbours {
if node == neigbour {
return true
}
}
return false
}
