auto Summary Declares a variable using local-variable type inference. Syntax auto name1 = value1 [, name2 = value2 [, name3 = value3 ... [, nameN = valueN]]]; Parameters nameN The name for the variable. This can be any valid identifier. valueN Required. Initializes the variable to a value. This can be any valid expression. Description The auto keyword declares a variable with the data type of the initialized expression. 123class Foo {} auto foo = new Foo(); // Variable 'foo' has type 'Foo' auto variables must always be initialized because they retain the type of initialized expression. auto is typically used as a convenience for instantiating classes. It is not recommended to use auto for primitive types such as bool. See Also Variable Declaration var Share HTML | BBCode | Direct Link
