How to create a directory in C++
You will need admin access to create or delete a folder in C:\Users. Make sure that you are running the .exe as admin, to ensure you have these privileges. If you do not, then CreateDirectory will fail.
To get the error that is returned, use GetLastError. For a reference on the errors that may return, please take a look at the "Return value" section at

Also, the code you are looking for is
CreateDirectory ("C:\\Users\\morons", NULL);As there needs to be a "\\" before "morons"
Making a windows application cross-platform, was using CreateDirectory() c++17 standard now has std::filesystem::create_directories
#include<iostream>#include <filesystem>int main(){ std::filesystem::create_directories("C:\\newfolder\\morons");}Needs changes in makefile to -std=c++17 and updating to a GCC compiler that supports c++17.
In visual studio follow steps here to enable c++17
