Go无法从字符串创建全局字节片

Question

I am trying to make a global byte array from a string with:

var operators = []byte {"+-*/%"}

however, I am getting the error

cannot use string("+-*/") (type untyped string) as type byte in array or slice literal

What am I doing wrong here?

Answer 1

Use a type conversion to convert a string to a slice of bytes. Note the use of () instead of {}.

 var operators = []byte("+-*/%")

The code in the question is a composite literal.
