get directory from file path c++

Question

What is the simplest way to get the directory that a file is in? I\'m using this to find the working directory.

string filename = \"C:\\MyDirectory\\MyFile.b         


        

Answer 1

The quick and dirty:

Note that you must also look for / because it is allowed alternative path separator on Windows

#include 
#include 

std::string dirnameOf(const std::string& fname)
{
     size_t pos = fname.find_last_of("\\/");
     return (std::string::npos == pos)
         ? ""
         : fname.substr(0, pos);
}

int main(int argc, const char *argv[])
{
     const std::string fname = "C:\\MyDirectory\\MyFile.bat";

     std::cout << dirnameOf(fname) << std::endl;
}
