[go-nuts] New to Golang : Passing Array of struct to function

Hi,

I am new to Golang and trying my hand on basic Student class to search for
student for the corresponding roll number but it is giving many errors and
I am not able to understand how to call this function exactly. Here is my
complete code and also please guide me , where I can improve more (I know I
have a lot to :P) and any particular place from where I can study golang in
depth.

package main

import (
     "fmt"
)

type student struct {
     name string
     roll int
     marks [3]int
}

func (s student) totalMarks() (int) {
     total:=0
     for i,_:=range s.marks {
         total=total+s.marks[i]
     }
     return total
}
  func (s student) search(stud *[]student,roll int) (student) {
     for i:=0;i<len(stud);i++ {
         if stud[i].roll==roll {
             fmt.Println("Found the student")
             return stud[i]
         }else{
             fmt.Println("No such student exists")
             return
         }

     }

  }

func main() {
     var name string
     var roll int
     var marks [3]int
     var num int

     fmt.Print("Enter number of students you want to enter in record : ")
     fmt.Scan(&num)
     stud:= make([]student,num)

     for i:=0;i<num;i++ {

     fmt.Println("Enter the name : ")
     fmt.Scan(&name)
     fmt.Println("Enter roll number : ")
     fmt.Scan(&roll)
     fmt.Println("enter marks of 3 subjects")
     for i:=0;i<3;i++ {
         fmt.Scan(&marks[i])
     }
     s:=student{name,roll,marks}
     avg:=s.totalMarks()/3
     fmt.Println("the total is ",s.totalMarks())
     fmt.Println("average is ",avg)
     stud[i]=s;

  }


  }

Any comment or suggestion appreciated.

Thanks & Regards
