How do I create a directory in a given path in C++?

I need to make a function that creates a directory in a subdirectory of the current location. Here is what I've tried:

#include <iostream>
#include <cstring>
#include <dir.h>
#include <stdlib.h>
using namespace std;

void create(){
    char nume[50];
    int directory1,directory2;
    directory1=mkdir("folder1");
    directory2=mkdir("/folder1/ name1");
}

int main()
{
    create();
}

When I run this code, the "folder1" directory does get created, but "name1" doesn't. What am I doing wrong? I also tried doing this:

#include <iostream>
#include <cstring>
#include <dir.h>
#include <stdlib.h>
using namespace std;

void create(){
    char nume[50];
    system("mkdir folder1");
    system("mkdir /folder1/name1");
}

int main()
{
    create();
}

But I get a "The syntax of the command is incorrect" message.

I would suggest using the <filesystem> library which is available as of C++17, in this case using std::filesystem::create_directories

#include <filesystem>

void create()
{
    std::filesystem::path subfolder = "/folder1/name1";
    std::filesystem::create_directories(subfolder);
}

int main()
{
    create();
}

Note that create_directory assumes all parent directories exist, otherwise create_directories will create intermediate directories if missing.
