c++ how to remove filename from path string
c++, filesystems, string
Solution
The easiest way is to use `find_last_of` member function of `std::string`
string s1("../somepath/somemorepath/somefile.ext");
string s2("..\\somepath\\somemorepath\\somefile.ext");
cout << s1.substr(0, s1.find_last_of("\\/")) << endl;
cout << s2.substr(0, s2.find_last_of("\\/")) << endl;
This solution works with both forward and back slashes.
Problem
I have ``` const char *pathname = "..\somepath\somemorepath\somefile.ext"; ``` how to transform that into ``` "..\somepath\somemorepath" ``` ?
