下个可用字符 c 是以Traits::eq(c, delim) 确定的分隔符。提取该分隔符(与 basic_istream::get() 不同)并计入 gcount(),但不存储它。 count 非正,或者已经提取了 count - 1 个字符(此时会调用 setstate(failbit))。 如果函数没有提取字符,那么在调用 setstate() 前就会在局部错误状态中设置 failbit...

所谓的确是std::basic_ios::operator void*(),而不是sentry::operator bool(),它与std::getline()返回a std::basic_istream(因此,a std::basic_ios)而不是哨兵的事实是一致的. 对于非信徒,请参阅: cppreference网站上的std :: basic_ios :: operator void*()文档, 关于artima 的The Safe Bool Idiom...
来自注释部分https://en.cppreference.com/w/cpp/string/basic_string/getline When consuming whitespace-delimited input (e.g. int n; std::cin >> n;) any whitespace that follows, including a newline character, will be left on the input stream. Then when switching to line-oriented input, the...
std::getline - cppreference.com 通过以上方法,你应该能够解决 std::getline 调用不起作用的问题。如果问题仍然存在,请检查是否有其他代码影响了输入流的状态。相关搜索: 为什么在循环中调用std::getline之后,C++ fstream需要调用clear() 为什么std::getline()的结果不符合预期 为什么`putStrLn getLine`不起作...

Edit & run on cpp.sh this getline(cin,variable); is kind of a weird notation. I assume it is some function of inputstream and variable? what other 1st argument could I use there? also I have seend the notation cin.getline(...); how does that work what are the parameters? I didnt...
