Let's study aggregates structures

Hello !  If you can observe everything build something. Let's say if i draw a picture i need my tools which are paper and pencil. If i build my own house i need bricks, wood, iron etc. if i build my own software platform then I need open my toolkit. As a programmer we need language, problem and solution.

Everything you see in this universe, so complex. We need basic or simplified version, so that we know how this work.

1. Array
2. Slice
3. Maps
4. Structs  

Array:

          Array you familiar about. This is old concept 

 Array is just like a memory. Array allocate space continuous form. As you seen above.

In golang array have fixed sized.  

This Program store one student performance in whole semester. 

package main
import (
"fmt"
)
func main() {
array := [5]float64{30.0,60.0,50.0,20.0}
var total float64 = 0.0
for i , _ := range array{
total+= array[i]
}
t := total/float64(len(array))
fmt.Println(t)
} 

Array are comparable with arrays. Array of different sizes can't compare. You can omit size by adding "..." between []

        data := [...]int{1,2}

There's few problems that array is not a good choice.

    fixed length

    mutate 

The better version is called Slice which is totally new and interesting topic. 

 Multidimensional Array:

If I know how to create array, i try to make tic toc game for better understand how this works. When Yesterday, i was doing that first problem is how i create multidimensional array, then i figure out how i create this.

          seed := [fixed size of rows ][fixed size of columns]int{}

   Tic toc is easy board game and best example for multidimensional array. Try yourself
