Example
- Typed variables are either declared explicitly or inferred
- Assignment is
= - Both multiple declaration and assignment
- Numeric initialize default to zero
:=→ declaration of, inference and assignment to
// var declares 1 or more variables. var a string = "initial" fmt.Println(a) // You can declare multiple variables at once. var b, c int = 1, 2 fmt.Println(b, c) // Go will infer the type of initialized variables. var d = true fmt.Println(d) // Variables declared without a corresponding initialization are zero-valued. For example, the zero value for an int is 0. var e int fmt.Println(e) // The := syntax is shorthand for declaring and initializing a variable, e.g. for var f string = "short" in this case. f := "short" fmt.Println(f)
initial 1 2 true 0 short
