ofstream返回错误“没有匹配函数调用std :: basic_ofstream <char> :: close（const char [14]）”

Question

Need help fixing my code, not sure what's wrong. I'm using C++11, trying to write a vector to a file by individually writing each struct. The section of code returning an error is:

string craigSave = "craigSave.txt";
ofstream file(craigSave.c_str());
file.open("craigSave.txt");
for (int i=0; i<finalVector.size(); i++){
    file << finalVector[i]<<endl;
}
file.close("craigSave.txt");
cout<<"Thanks for shopping!"<<endl;
done = true;

The error returned is on the "file.close" line and is:

error: no matching function for call to 'std::basic_ofstream::close(const char [14])'

I research on this error seems to point to needing to use char* as an argument instead of a string, but I'm using C++11, so it should accept strings. Also it is strange that there is no error for the file.open line, as all research shows the error being there, not at file.close

Just use file.close(); , there's no need to pass the file name again.

See http://www.cplusplus.com/reference/fstream/ofstream/close/ .

Also, ofstream s are RAII objects, which means that the file will automatically be closed once the ofstream object goes out of scope (see do I need to close a std::fstream? ):

{
    ofstream out("name");
    // do something with out...
} // out.close is called automatically
