How Can Boost Efficiently Split a String into a Vector of Strings in C ?

Efficient String Splitting into a Vector of Strings

In the realm of string manipulation, the need to parse a string into individual segments often arises. When dealing with space- or comma-separated strings, it's essential to employ the most efficient and flexible approach. Therefore, let's delve into the best practice for splitting a string into a vector of strings.

Harnessing the Power of Boost

Boost, a comprehensive C library, offers a robust solution for string splitting: its string algorithms library. This library provides an elegant and efficient means to achieve our goal.

Code Implementation

#include <boost/algorithm/string/classification.hpp> // Include boost::for is_any_of
#include <boost/algorithm/string/split.hpp> // Include for boost::split

// ...

std::vector<std::string> words;
std::string s;
boost::split(words, s, boost::is_any_of(", "), boost::token_compress_on);

This code leverages boost::split to parse the string s into its constituent segments and store them in the vector words. The boost::is_any_of function identifies the delimiter characters (space and comma), and the boost::token_compress_on directive prevents adjacent delimiters from creating empty strings in the resulting vector. This allows for efficient and accurate string splitting.
