[Solved] How to access struct’s instance fields from a function?

by


Here is one example:

package main

import (
    "fmt"
)

// example struct
type Graph struct {
    nodes   []int
    adjList map[int][]int
}

func New() *Graph {
    g := new(Graph)
    g.adjList = make(map[int][]int)
    return g
}

func main() {

    aGraph := New()
    aGraph.nodes = []int {1,2,3}

    aGraph.adjList[0] = []int{1990,1991,1992}
    aGraph.adjList[1] = []int{1890,1891,1892}
    aGraph.adjList[2] = []int{1890,1891,1892}

    fmt.Println(aGraph)
}

Output:&{[1 2 3 4 5] map[0:[1990 1991 1992] 1:[1890 1891 1892] 2:[1790 1791 1792]]}
