Explain the difference between short declaration := and the var keyword in Go.
- The := operator is used for short declaration and assignment, creating a new variable with inferred type.
- The := operator is used for variable declaration, and you must specify the type explicitly.
- The var keyword is used for short declaration and assignment, inferring the type automatically.
- The var keyword is used for variable declaration, and you must specify the type explicitly.
In Go, := is used for short declaration and assignment, which creates a new variable and infers its type from the assigned value. On the other hand, the var keyword is used for variable declaration, where you must explicitly specify the type. For example, x := 10 creates a new variable x with an inferred type of int, while var y int declares a variable y of type int.
