Question

I want to delete a file whose path is stored in a std::string object.
I know remove() in <cstdio>, but it takes a const char * as argument.
So is there any direct method to delete the file, like a function which takes the string object as its input?

Answer 1

How about:

string fileName;
//...
remove(fileName.c_str());

Of course, you can always define

int remove(std::string const& fileName)
{
    return remove(fileName.c_str());
}
