Dir path in C++

In C++, we can get the directory path of a file using the std::filesystem library. This library was introduced in C++17, so make sure your compiler supports it. The following code snippets demonstrates how to get the directory path of a file:

#include 
#include 
int main() {

    // path to the target file

    std::filesystem::path filePath("C:\\User\\Documents\\example-file.txt");
// get the directory path of the target file

    std::filesystem::path dirPath = filePath.parent_path();
// print the directory path

    std::cout << "Directory path: " << dirPath << std::endl;
return 0;

}

Output:

Directory path: C:\User\Documents

Here, parent_path() is a member function of the std::filesystem::path class, which returns the parent directory path of the target file. In the example, the target file path is "C:\User\Documents\example-file.txt", and the parent path is "C:\User\Documents".

Note that the forward slash ("/") can also be used instead of the backslash ("\").
