C ++如何将来自stdio的输入字符串放入向量，每个容器元素一个字 [英] C++ how to put an input string from stdio into a vector, one word per container element

问题描述

我正在学习c ++，我有点新手。我已经研究了这个问题了很多。我在c ++中学习过矢量，字符串和字符串流，但我仍然找不到正确的方法来做到这一点。

基本上，我想写，在命令行中的一些文本，并且将一些放入在位置0和文本的向量容器中放置在位置1的同一容器中。

我发现了很多方法可行，但没有什么只是这样做。

感谢您的帮助。

解决方案

  #include< string> 
 #include< iostream> 
 #include< sstream> 
 #include< vector> 
 #include< algorithm> 
 #include< iterator> 
 
 int main（）{
 std :: string line; 
 std :: getline（std :: cin，line）; //从cin 
读取一行std :: stringstream buffer（line）; 
 std :: vector< std :: string>话; 
 //将每个单词从行复制到单词
 std :: copy（std :: istream_iterator< std :: string>（buffer），
 std :: istream_iterator< std :: string& （），
 std :: back_inserter（words））; 
} 
  

I'm learning c++, and I'm a bit of a newbie. I've researched this question quite a bit. I've studied vectors, strings, and stringstreams in c++ but I still can't find the 'right' way to do this.

Basically, I want to write, "some text" at the command line and have "some" put into a vector container at position '0' and "text" put into the same container in position '1'.

I've found a lot of ways that sorta work, but nothing that just does that.

Thanks for the help.

解决方案

As per your comment:

#include <string>
#include <iostream>
#include <sstream>
#include <vector>
#include <algorithm>
#include <iterator>

int main() {
    std::string line;
    std::getline(std::cin, line); // read one line from cin
    std::stringstream buffer(line);
    std::vector<std::string> words;
    // copy each word from line to words
    std::copy(std::istream_iterator<std::string>(buffer),
              std::istream_iterator<std::string>(),
              std::back_inserter(words));
}
