Lambda expressions

A lambda expression (or lambda function) is a convenient way of defining an anonymous, small, and one-time use function to be used in the place right where it is needed. Lambda is particularly useful with Standard Template Library (STL), as we'll see.

How to do it...

In this section, we'll write some code in order to get familiar with lambda expressions. Although the mechanics are important, pay attention to the code readability with lambda, especially in conjunction with STL. Follow these steps:

1. In this program, the lambda function gets an integer and prints it to standard output. Let's open a file named lambda_01.cpp and write the following code in it:

#include <iostream...
