stringstream strm;
sstream strm(s)
strm.str() return a copy of a string
strm.str(s) copies the string into strm return void.

当我将变量分配给 Stringstream 时，我正在寻找更多功能。我将如何忽略标点符号？我的书上面只列出了这两个功能

struct PersonInfo{
string name;
vector<string> numbers;
}
string line, word;
vector<PersonInfo> people;
while(getline(cin, line))
{
    PersonInfo Info;
    istringstream record(line);
    record >> info.name;
    while (record >> word)
       info.numbers.push_back(word);
    people.push_back(info);
}

Answer 1

How would I ignore punctuation mark? My book only listed those two function above.

使用 std::getline，它接受一个分隔符参数：

if(! std::getline(record, line, ' ') ) // reads to first space
    throw std::runtime_error{ "bad stream format" };

您应该阅读一个分隔符，并将分隔符替换为“”或“;”。
