@ -80,6 +80,7 @@ There are three kinds of ways to initialize variables:
var v1 int = 10 // method 1 var v1 int = 10 // method 1
var v2 = 10 // method 2 var v2 = 10 // method 2
v3 := 10 // method 3 v3 := 10 // method 3
v4 := [3]int{1, 2, 3} //initialize a slice
``` ```
It can be observed that the compiler can deduce the data type automatically. However, when we use **method 3**, the variable should not be declared before, which will contribute to the error.

# To_get_start
## Structure and Compilation
Let's first create a file called "Hello_JOJ.go", and write in:
```go
package main
import (
"fmt"
)
func main(){
fmt.Println("Hello "+ "JOJ")
}
```
Observe the structure it is similar to both Python and C++, as it needs to import certain library and need some special package to run the program. We will also see further that the syntax of Go is like the combination of both C++ and Python.
If you want to run the program, you can either choose to directly run it:
```bash
$ go run Hello_JOJ.go
```
or choose to compile it as a binary file:
```bash
$ go build Hello_JOJ.go
$ ./Hello_JOJ
```
