I've got some values in a list in Go. I just need to be able to print them but every time I try it tells me test.FirstName undefined (type *list.Element has no field or method FirstName).
So how to I appropriately access the members of the list? Its the last couple of lines that are giving me trouble.
package main
import (
"bufio"
"fmt"
"log"
"strconv"
"strings"
"os"
"container/list"
)
type Student struct {
FirstName string
LastName string
testScore int
homeworkScore int
}
func main() {
fmt.Println("What is the name of your file?
")
var filename string
fmt.Scan(&filename)
file, err := os.Open(filename)
if err != nil {
log.Fatal(err)
}
scanner := bufio.NewScanner(file)
//var numLineCount int = 0
var gradeCount = 0
var student Student
var studentList list.List
var studentCount int = 1
for scanner.Scan() {
line := scanner.Text()
fields := strings.Fields(line)
student.FirstName = fields[0]
student.LastName = fields[1]
scanner.Scan()
line2 := scanner.Text()
sum := 0
gradeCount = 0
for _, field := range strings.Fields(line2) {
n, err := strconv.Atoi(field)
if err != nil {
log.Fatal(err)
}
gradeCount++
sum += n
}
student.testScore = sum/gradeCount
gradeCount = 0
scanner.Scan()
line3 := scanner.Text()
sum2 := 0
for _, field := range strings.Fields(line3) {
n, err := strconv.Atoi(field)
if err != nil {
log.Fatal(err)
}
gradeCount++
sum2 += n
}
student.homeworkScore = sum2/gradeCount
studentList.PushBack(studentCount)
studentCount++
fmt.Println("First:", student.FirstName, "Last:", student.LastName, "Test Avg:", student.testScore, "Homework Avg:", student.homeworkScore)
}
test:=studentList.Front()
fmt.Println(test.FirstName)
}
update: so I figured out i can't use test.FirstName in the println part, just Println(test) works and prints everything. but I still need to be able to access each element of the list. How can I do so?
