C++0x Automates Type Deduction with auto

Tired of typing unwieldy type names in variable declarations? Why not let the compiler do that dirty job, automatically deducing the type from the variable's initializer?

nother C++0x feature is going to simplify the way you write C++ code. Instead of tediously writing the type of a variable when you declare it, a C++0x compiler will deduce the variable's type automatically simply by looking at its initializer—if you ask it to. The following sections will demonstrate how to use this feature.

Declaring the type of certain variables (for example, iterators) leads to code clutter and maintenance difficulties.

Use the revamped auto keyword to let the compiler automatically deduce a variable's type from its initializer.
