当你在使用C++标准库中的std::basic_ifstream类时遇到“no matching function for call to 'std::basic_ifstream<char>::basic_ifstream(...)'”这样的编译错误,通常意味着你提供的构造函数参数与std::basic_ifstream所期望的参数不匹配。以下是一些可能导致这种错误的常见原因以及相应的解决方法: 1. 确认错误信...

error: no matching function for call to 'std::basic_ifstream<char>::open(std::string&) 原因是C++的string类无法作为open的参数。 解决方案:使用C的字符串。 例: char filename[10]; strcpy(filename, "1.txt"); ifstream fin; fin.open(filename);...
