How to Split a String into a Vector of Strings in C

Splitting a string into a vector of strings is a common task in many programming tasks. Several approaches can be used to achieve this, but finding the most efficient and effective method is crucial.

One recommended approach for splitting strings in C is to utilize the Boost C Libraries. Boost provides a comprehensive string algorithms library that includes functions specifically designed for string manipulation.

To split a string using Boost, you can follow these steps:

#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);

In this code snippet:

• #include <boost/algorithm/string/classification.hpp> and #include <boost/algorithm/string/split.hpp> include the necessary Boost libraries.
• std::vector<std::string> words; declares a vector to store the split strings.
• std::string s; represents the input string you want to split.

• boost::split(words, s, boost::is_any_of(", "), boost::token_compress_on) performs the splitting operation. It takes the following parameters:

  • words: The vector to store the split strings.
  • s: The input string to be split.
  • boost::is_any_of(", "): A predicate that identifies the delimiter characters (comma and space in this example).
  • boost::token_compress_on: An optional parameter that ignores multiple consecutive delimiters.
