Interview
- When is
defercalled?It was called according the consuming sequence of stack. That is to say, the first
deferclause will be invoked as the last. deferandpanicwhich is run first?First
defer, thenpanic.- Difference between
new()andmake()?For
newfunction, it returns pointer. It is used when initiate struct.Makeis mostly used when initiate slice, map and channel. - Can
append()receive pointer as parameter?No.
- go run order,
- Can global variable declared with short declaration?
No.
- Difference between passing value and passing pointer as parameter of function?
When passing value, it will create a new copy. For pointer, it will pass the value itself.
str := "hello", str[1] = 'a'Is the string gonna modified?No. Because the string is a constant.
- Can we assign nil to
string?No. But we can assign nil to
*string - If
mapandrangeis executed by sequence?No.
- If two slice object can be compared with
==?No.
- Is there a difference between new() and “regular” allocation?
No. &Vector{} ， new(Vector) is the same, one thing to note: new() is the only way to get a pointer to an unnamed integer or other basic type. You can write "p := new(int)" but you can't write "p := &int{0}".
