error: no matching function for call to 'std::basic_ifstream<char>::open(std::string&)

676 查看
string filename = "1.txt"; ifstream fin; fin.open(filename);
上述语句会产生如下错误：
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);
