在C++中,遇到错误信息 "[error] cannot bind 'std::istream {aka std::basic_istream<char>}' lvalue to..." 通常意味着你试图将一个非常量的 std::istream 对象(如 std::cin)绑定到一个非常量引用上,但这是不被允许的。下面我会详细解释这个问题并提供解决方案。 1. std::istream 和lvalue 的含义...

应该是写了cin<<之类的，方向反了
std::basic_istream::ignore用于从输入字符串中提取字符并丢弃包含定界字符的字符,即,如果到达文件末尾,此函数将停止提取字符。分隔字符是换行符,即“ \ n”。如果使用文件进行输入,则如果到达文件末尾,此函数还将停止提取字符。此函数通过首先构造哨兵对象来访问输入序列。它从关联的流缓冲区对象中提取字符,并在返...
