title: Initializing single element of string array into another string variable in Go lang
body: <p>In this code, I read a text file for input (A1,B2) and Im using the split function to separate them at comma and store in strs, according to the function definition its returns a array in this case it is strs array, i want the first element in strs to be in currentSource and the second element to be in CurrentDest.I tried printing both the variables individually to check if its working,but the program exits after that and  I get a error saying Panic: index out of range. 
  Can anybody help me out..!!!</p>
  
  <pre><code>var currentSource string
  var currentDest string
  
  func main() {
  
      file, err := os.Open("chessin.txt")
      if err != nil {
          fmt.Println(err)
      }
      defer file.Close()
      scanner := bufio.NewScanner(file)
      for scanner.Scan() {
          strs := strings.Split(scanner.Text(), ",")
  
          currentSource = strs[0]
          currentDest = strs[1]
  }
