c++11 auto

C++11 introduced the `auto` keyword, which allows for type inference during variable declaration. Instead of explicitly specifying the type of a variable, you can use `auto` and let the compiler deduce the type based on the initializer expression.

Here's an example:

auto x = 42;  // x is deduced as int
auto str = "Hello, World!";  // str is deduced as const char*
auto result = someFunction();  // result is deduced based on the return type of someFunction()

Using `auto` can help reduce verbosity and make code more concise, especially when dealing with complex types or template metaprogramming. However, it's important to note that `auto` does not imply dynamic typing or reflection; it is still statically typed and checked at compile time.
