我的代码应该打开100个文件(并用它们做一些事情),路径中的下一个索引如: “c:\ Naprzeme \ NAPRZ100.IN”下一个是“c:\ Naprzeme \ NAPRZ101.IN”等等:

for (int as=100;as<159;as++){
    ostringstream ss;
    ss << as;
    string cherk = ss.str();
string supremeCounter = "c:\\Naprzeme\\NAPRZ"+cherk+".IN";
fstream infile(supremeCounter);
//....other code here
}

fstream infile(supremeCounter)返回错误

28 31 C:\Users\talent\Documents\File.cpp [Error] no matching
 function for call to     'std::basic_fstream<char>::basic_fstream(std::string&)' 
candidates are: //(here some libs)...
