Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.
boost::split in C++ library
This function is similar to strtok in C. Input sequence is split into tokens, separated by separators. Separators are given by means of the predicate.
Syntax:
Template: split(Result, Input, Predicate Pred); Parameters: Input: A container which will be searched. Pred: A predicate to identify separators. This predicate is supposed to return true if a given element is a separator. Result: A container that can hold copies of references to the substrings. Returns: A reference the result
Application : It is used to split a string into substrings which are separated by separators.
Example:
Input : boost::split(result, input, boost::is_any_of("\t"))
input = "geeks\tfor\tgeeks"
Output : geeks
for
geeks
Explanation: Here in input string we have "geeks\tfor\tgeeks"
and result is a container in which we want to store our result
here separator is "\t".
CPP
// C++ program to split// string into substrings// which are separated by// separator using boost::split// this header file contains boost::split function#include <bits/stdc++.h>#include <boost/algorithm/string.hpp>using namespace std;int main(){ string input("geeks\tfor\tgeeks"); vector<string> result; boost::split(result, input, boost::is_any_of("\t")); for (int i = 0; i < result.size(); i++) cout << result[i] << endl; return 0;} |
Output:
geeks for geeks
