(C++) How to get a file's path

include <string>

include <assert>


//Returns the path, ending with a backslash '\'
std::string getPath(const std::string& fileName)
{
  const int endOfPathIndex = fileName.rfind("\\",fileName.size());
  assert(endOfPathIndex < static_cast<int>(fileName.size()));
  return fileName.substr(0,endOfPathIndex+1);
}
int main()
{
  assert(getPath("test\\file.exe")=="test\\");
  std::cin.get();
}
