Types — An Introduction to Programming in Go Go Resources

WebNov 6, 2024 · In go, the basic types are not nillable. A statement like var a int = nil does not compile because an int can never be nil. The default value of an unassigned int type is 0. Running the statement var a int // default value of int, cannot be nil fmt.Println (a) // 0 will output the default value of int; “ 0 ”. WebFollowing are the default types for various constants in Golang - So, in the statement var a = 5, since no explicit type information is available, the default type for integer constants is used to determine the type of a, which is int. Typed Constants In Golang, Constants are typed when you explicitlyspecify the type in the declaration like this- You can't return nil for any type. If int is used as the type argument for T for example, returning nil makes no sense. nil is also not a valid value for structs. What you may do–and what makes sense–is return the zero value for the type argument used for T. cufflinks without french cuffs
