first sentence
The questions in the previous issue are relatively simple and the accuracy rate is relatively high. Take a look together.
What does the following code output?
package main
import "fmt"
func main() {
const c = 8
a := &c
*a = 12
fmt.Println(*a)
}
A: 8; B: cannot compile; C: 12
Correct Answer: B. The error reported is: invalid operation: cannot take address of c (untyped int constant 8).
Check out this topic. What does the following code output?
package main
import "fmt"
func main() {
a := []int{7, 8, 9}
fmt.Println(a[real(2)])
}
