You could use std::getline(cin, tab).
你可以使用std::getline(cin, tab).
回答by Jerry Coffin
You probably want to use std::getline, specifying whatever character you want to mark the end of the sentence (e.g., '.').
您可能想要使用std::getline, 指定要标记句子结尾的任何字符（例如，'.'）。
回答by dutt
What you want is to do a getline in some form.
你想要的是以某种形式做一个 getline 。
string str;
cin.get(str, 25);
cout <<"\"" <<str <<"\"" <<endl;
or
或者
string str;
cin.getline(str, 25);
cout <<"\"" <<str <<"\"" <<endl;
Both accept a third parameter, a char, that specifies what to consider the end of the line. For details see http://www.minich.com/education/wyo/cplusplus/cplusplusch10/getfunction.htm
两者都接受第三个参数，一个字符，它指定要考虑行尾的内容。详情见http://www.minich.com/education/wyo/cplusplus/cplusplusch10/getfunction.htm
