此函数类似于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。
句法：
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
应用程序：用于将字符串拆分为子字符串，这些子字符串由分隔符分隔。
例子：
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".
// C++ program to split
// string into substrings
// which are separated by
// separater using boost::split
// this header file contains boost::split function
#include
#include
using namespace std;
int main()
{
string input("geeks\tfor\tgeeks");
vector 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：
geeks
for
geeks
