How can I create directory tree using C++ in Linux?

In this section we will see how to create a directory tree using C++ code in Linux. In Linux terminal we can put some command like “mkdir –p /dir/dir1/dir2” Here –p is used to mark as parent (recursively create inner directories).

In C++ code we can use some libraries of Linux system. Then we can use Linux terminal commands as string argument of the system() function. We can create directory tree like this.

Example

#include <bits/stdc++.h>
#include <iostream>
#include <sys/stat.h>
#include <sys/types.h>
using namespace std;
int main() {
   int status;
   status = system("mkdir -p TP/My_Folder/test"); // Creating a directory
   if (status == -1)
      cerr << "Error : " << strerror(errno) << endl;
   else
      cout << "Directories are created" << endl;
}
