如何使用C++库中的boost::split（示例）

此功能类似于C中的strtok。输入序列被拆分为标记, 并由分隔符分隔。分隔符是通过谓词给出的。
语法如下：

Template:split(Result, Input, PredicateT 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

【如何使用C++库中的boost::split（示例）】应用范围：它用于将字符串拆分为由分隔符分隔的子字符串。
例子：

Input : boost::split(result, input, boost::is_any_of("\t"))input = "geeks\tfor\tgeeks"Output : geeksforgeeksExplanation: Here in input string we have "geeks\tfor\tgeeks"and result is a container in which we want to store our resulthere separator is "\t".

// C++ program to split // string into substrings // which are separated by // separater 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; }

输出如下：
