Syntax error: unexpected <token> error in Golang
In Golang, the "syntax error: unexpected <token>" error occurs when there is a syntax error in your code, such as a missing semicolon or misplaced brace. This error indicates that the compiler has encountered a token that it was not expecting at that point in the code.
Example
package main
import "fmt"
func main() {
fmt.Println("Hello, World!"
}
In this program, we are trying to print "Hello, World!" to the console using the fmt.Println() function. However, we have missed a closing parenthesis for the Println() function call.
When we try to compile and run this program, we will encounter the following error:
Output
./main.go:7:1: syntax error: unexpected }
This error occurs because the compiler was expecting a closing parenthesis at the end of the fmt.Println() function call, but instead it encountered a closing brace for the main() function.
To fix this error, we simply need to add the missing closing parenthesis, like this:
Example
package main
import "fmt"
func main() {
fmt.Println("Hello, World!")
}
In this modified program, we have added the missing closing parenthesis for the fmt.Println() function call. This code will compile and run without any errors.
In summary, the "syntax error: unexpected <token>" error in Golang occurs when there is a syntax error in your code, such as a missing semicolon or misplaced brace. To fix this error, you need to identify and correct the syntax error in your code.
