Boost is a set of libraries for Advanced C++ Programming. It is used by coders to perform various tasks like multithreading,
image processing, regular expressions, unit testing etc using the inbuilt source libraries. It is used for competitive
programming and meta programming.
We will study specifically about Boost.Regex here!
Regex refers to RegularExpressions. Regular Expressions can be defined as a sequence of symbols and characters expressing a string or pattern to be searched for within a longer piece of text. The <boost/regex> header provides various template classes that are very flexible to use. The use of Regex Expressions under Boost library, increases the accuracy and precision of operations. It also reduces the chances of error.
