使用矩阵接口作为参数的Go函数

Question

I don't know how to use an interface as a parameter for a function, I keep getting a syntax error:

syntax error: unexpected comma, expecting {

But it looks the same as any other function:

func getWall(array [][]interface, wallSize float64){
  var currentWall, highWallPrice float64 = 0, 0;
  err := false
  i := 0
  for highWall < wallSize {
    if i >= (len(array)) {
      fmt.Println("Not enough offers for pair " + pair)
      currentWall = wallSize
      err = true
    }else{
      price = getFloat(array[i][0].(string))
      amount = getFloat(array[i][1].(string))
      currentWall = currentWall + price * amount
       i++
    }
  }
  if !fail {
    wallPrice = getFloat(array[i][0].(string))
  }
  return wallPrice, err
}

I'm starting to learn golang any help is appreciated.

Answer 1

The error comes from func getWall(array [][]interface, wallSize float64){ because your parameter need to look like this [][]interface{}
