I’m getting this error: expected expression syntax
Not sure why it’s happening. I’m new in Go programming. It’ll be wonderful if someone helps me out.
Here’s the code:
package main
import "fmt"
func main() {
x := [5]int
x[4] = 100
fmt.Println(x)
}

I copied your code into and created a link by clicking the “Share” button.
When I run your code, I get an error:
./prog.go:7:10: type [5]int is not an expression
Go build failed.
That error is telling you that “type [5]int” is not an expression: It’s a type. It’s the same as saying x := string
or x := int
.
If your goal was to define a variable of type [5]int
, then you have to write it as:
var x [5]int
You could rewrite this declaration into a “short form” like this:
x := [5]int{}
[5]int
is a type, but [5]int{}
is an expression which creates a [5]int
array with all its elements set to the int
default value: 0
.
