boost :: split ()

#include <iostream>
#include <vector>
#include <string>
#include <boost/algorithm/string.hpp>

using namespace std;

int main()
{

    // String to split

    string str = "You're supposed to see this!|NOT THIS!!!!!!";

    // Line container

    vector<string> lines;

    // Splits string

    boost::split(lines, str, boost::is_any_of("|"), boost::token_compress_on);

    // Outputs 1 half of the split string

    cout << lines.at(0).c_str() << endl;

    // Waits for input before program exits

    cin.get();

    return 0;
}

psuedocode에 있는 프로그램은 다음과 같습니다.

문자열 str을 선언 하고 이것을 "당신은 이것을 보게된다!"라고 설정 하십시오! | NOT NOT this !!!!!! " .

문자열 유형의 벡터 선 을 선언하십시오 .

regex "|"인 경우 문자열 str 을 벡터 라인 으로 분할 합니다. 발견된다.

행의 인덱스 0에있는 객체를 인쇄 합니다.
